Job Change returns results synchronously from the launcher. Use this endpoint to **re-fetch or audit** a previous job — not to poll for completion. ## Job change status values | Value | Meaning | | ----------- | -------------------------------------------------------------------- | | `moved` | Contact has started a new role at a different company. | | `left` | Contact appears to have left the company with no current role found. | | `no_change` | Contact is still at the input company. | | `unknown` | Profile could not be verified or no reliable update was found. | When `job_change_status` is `moved` or `left`, `output.person` contains the contact's current profile with their new role and employer. When `no_change` or `unknown`, `output.person` is an empty object `{}`. ## OpenAPI ````yaml api_specs.yaml GET /v1/job/change openapi: 3.1.0 info: title: Waterfall version: 1.6.0 description: >- Waterfall API provides a broad set of capabilities in V1. Most endpoints are asynchronous: you start a job (POST) and then retrieve results (GET). Some endpoints return immediate responses. Webhooks are also available to simplify asynchronous integrations. Below is an overview of the available endpoints: #### 1\. Prospector Find contacts at target accounts using filters like job titles and location. Get contact details such as titles, real-time verified emails, social profiles, and phone numbers. - **Prospector Launcher:** Start a contact search using a domain name, LinkedIn profile, or company name. Returns a `job_id`. - **Prospector Finder:** Retrieve results using the `job_id` from the Prospector Launcher. #### 2\. Contact Enrichment Enrich contact information by inputting professional/personal emails, LinkedIn URL/slug, or name + domain. Get enriched data like verified emails, job titles, and locations. - **Contact Enrichment Launcher**: Start a contact enrichment process. Returns a `job_id`. - **Contact Enrichment Finder**: Retrieve results using the `job_id` from the Contact Enrichment Launcher. #### 3\. Company Enrichment Enrich company data by inputting a domain, LinkedIn URL/slug, or company name. Receive details like headcount, industry, and headquarters. - **Company Enrichment Launcher**: Start a company search using a domain name, LinkedIn URL/slug, or company name. Returns a `job_id`. - **Company Enrichment Finder**: Retrieve results using the `job_id` from the Company Enrichment Launcher. #### 4\. Phone Number Enrichment Get mobile numbers by inputting an email, LinkedIn URL/slug, or name + domain. - **Phone Enrichment Launcher**: Start a phone number enrichment process. Returns a `job_id`. - **Phone Enrichment Finder**: Retrieve results using the `job_id` from the Phone Enrichment Launcher. #### 5\. Search Contact Search contacts using either a specific contact LinkedIn, a specific company, or company-set filters, with optional title, seniority, department, location, and hiring-date constraints. - **Search Contact Launcher**: Start a search contact job and get the result payload. - **Search Contact Finder**: Retrieve search contact job state and output by `job_id`. #### 6\. Search Company Search companies by industry, country, and company size filters with pagination support. - **Search Company Launcher**: Start a search company job and get the result payload. - **Search Company Finder**: Retrieve search company job state and output by `job_id`. #### 7\. Job Change Detect whether a contact has changed jobs using company and/or contact identifiers. - **Job Change Launcher**: Start a job change check and get the result payload. - **Job Change Finder**: Retrieve job change job state and output by `job_id`. #### 8\. Company Reveal Reveal company information from an IPv4 address and retrieve persisted reveal jobs by `job_id`. - **Company Reveal Launcher**: Submit an IPv4 and get the reveal job envelope immediately. - **Company Reveal Finder**: Retrieve a persisted company reveal job state and output by `job_id`. #### 9\. Email Verification Verify emails with high accuracy, reducing bounce rates. This endpoint works asynchronously, providing results in a single API call. You can start an email verification process and get the verification status of a given email. #### 10\. Account Reporter Provides information about your account's usage. #### 11\. API Keys Management Use a single master key to manage all your API keys: create new keys, activate/deactivate them, and view all your keys in one place. See [API Keys Management](https://docs.waterfall.io/v1/api-keys-overview). --- # Versioning Waterfall API versioning follows Semantic Versioning (`MAJOR.MINOR.PATCH`): - **Patch** (`1.1.x`): Non-breaking revisions and fixes only. No existing contract changes. - **Minor** (`1.x.0`, for example `1.2.0`): Backward-compatible additions. Adding new services/endpoints uses a minor version increase when existing services are unchanged. - **Major** (`x.0.0`, for example `2.0.0`): Breaking changes to existing contracts/behavior and major platform overhauls. ## Endpoint Lifecycle Stages Waterfall uses modern launch stages aligned with Google Cloud terminology: - **Preview** - Meaning: Early public version available for testing and feedback (equivalent to older Alpha/Beta phases). - Production use: Not recommended for critical production workloads. - SLA: No. - Stability: API behavior may change. - **GA (General Availability)** - Meaning: Fully released and production-ready service or API. - Production use: Yes. - SLA: Yes. - Stability: Backward compatibility is guaranteed within the version. - **Deprecated** - Meaning: Feature or API is scheduled for retirement and a newer alternative exists. - Production use: Should migrate away. - SLA: Limited. - Stability: No new features; removal date announced. - **Decommissioned / End of Life** - Meaning: Feature or API has been shut down and is no longer available. - Production use: No. - SLA: No. - Stability: Endpoint disabled or removed. Current mapping in this API spec: all endpoints are `GA` except `/v1/company-reveal`, `/v1/search/company`, `/v1/job/change`, and `/v1/company-titles`, which are `Preview`. --- # Authentication To access the API, you need the API key provided in your contract. You can ask for multiple API keys for different teams' usage. All API request URLs start with [https://api.waterfall.io/v1/](https://api.waterfall.io/v1/). Provide your API key in the `x-api-key` header. --- # Rate limit The Prospector, Search, Enrichment, Job Change and Verify Email APIs allow a maximum of 50 requests per minute (60 seconds). Should you encounter rate limit errors or anticipate a need for increased capacity, please reach out to your account manager for assistance. There are no rate limits for the Account Reporter API. ##### X-RateLimit-Limit The maximum number of requests you can make per interval. Only sent when the rate limit is reached. ##### X-RateLimit-Interval The length of the interval in seconds. Only sent when the rate limit is reached. ##### Retry-After The number of seconds to wait until the rate limit window resets. Only sent when the rate limit is reached. --- # Filters Waterfall offers three filtering options for prospect requests: ## 1. Title Filter The `title_filter` parameter allows requesting specific titles with each request. - If `title_filter` is present, it must not be empty. - If `title_filter` is present and not empty (for example `"title_filter": "((accountant) OR (accounting)) AND NOT (intern)"`), Waterfall will use that filter. - If `title_filter` is not present, Waterfall will try [title_filters](https://docs.waterfall.io/v1/prospector-multiple-title-filters). - At least one of `title_filter` or `title_filters` must be provided. The filter can be any Boolean expression. Accepted operators are `AND`, `OR`, and `NOT`. Operators must be uppercase and separated by spaces. There is no need to enclose multi-word titles in parentheses. Matching for each title is inclusive. For example: - `manager` will match `program manager`, `senior manager` and `account manager sales` - `vp data` will match `vp innovation, data science, co-founder`, `vp information and data` and `vp data science` - `head product` will match `global head of product` and `head of product management office` - `data lead` will match `lead data scientist`, `data lead engineer`, `data lead` and `data engineering lead` A few valid filter examples: - manager - manager AND NOT project manager - manager AND NOT (project manager OR sales manager) - ( (manager OR director) AND (sales OR marketing) ) AND NOT ( project manager OR sales manager) - (accountant OR accounting) AND NOT intern - ( (ceo) OR (c.e.o) OR (co-ceo) OR (coceo) OR (chief executive officer) OR (founder) OR (co-founder) OR (cofounder) OR (owner) OR (co-owner) OR (coowner) OR (cmo) OR (c.m.o) OR (chief marketing officer) OR (cco) OR (c.c.o) OR (chief commercial officer) OR (chief e-commerce officer) OR (chief ecommerce officer) ) OR ( ( (chief) OR (cheffe) OR (director) OR (vp) OR (svp) OR (vice) OR (president) OR (vicepresident) OR (executive) OR (head) ) AND ( (marketing) OR (growth) OR (e-commerce) OR (ecommerce) ) AND NOT ( (assistant) OR (analyst) OR (intern) OR (apprenticeship) OR (sales) OR (finance) OR (recruitment) OR (project manager) OR (hr) OR (human resources) OR (talent) OR (design) OR (logistic) OR (warehouse) OR (engineer) OR (developer) OR (student) OR (merchandising) OR (digital) OR (brand) OR (trade) OR (influencer) OR (export) OR (wholesale) OR (whole sale) OR (information) OR (specialist) ) ) A few invalid filter examples: - `mangerANDdirector`: spaces must be used around operators - `manager NOT (project manager)`: invalid boolean expression - `(accountant OR accounting AND NOT intern`: missing closing parenthesis before AND We recommend using parentheses to make sure operator precedence is what you intend. For example filter `(CFO) OR (Cofounder) AND NOT ((Vice) OR (Assistant) OR (Executive Assistant))` will match title `Assistant CFO.` The Boolean expression is `True OR False AND NOT True` and is evaluated as `True OR False AND NOT True = True OR False AND False = True OR False = True` In this case, the intended filter is `((CFO) OR (Cofounder)) AND NOT ((Vice) OR (Assistant) OR (Executive Assistant))`. Note the extra parenthesis around the first part. If you need help with writing title filters, contact your account manager to schedule a call with the support team. --- ## 2. Multiple Title Filters The `title_filters` parameter allows requesting multiple title filters in a specific order. It is used when [title_filter](https://docs.waterfall.io/v1/prospector-title-filter) is not present. Example: ``` json "title_filters": [ { "name": "ceo level", "filter": "ceo OR founder OR owner" }, { "name": "sales", "filter": "revenue OR growth OR sales" }, { "name": "marketing or operations", "filter": "marketing OR operations" } ] ``` Waterfall will try each filter in the order provided up to the requested `limit`. You can provide up to 5 `title_filters` entries per request. --- ## 3. Location Filter The location-based search is performed with `location_name`, `location_country`, and `location_countries`. #### location_country The `location_country` parameter represents the country of the contact's current address. Use full country names such as `United States` or `France`. Partial values such as `United` or `Saudi` should be avoided. The country list is available [here](https://waterfall-io-public.s3.amazonaws.com/waterfall_location_country.txt). Empty values are ignored. #### location_countries The `location_countries` parameter is a list of countries where the contact's current address can be. If it is present and non-empty, it is used instead of `location_country`. - \["France"\] - \["France", "Germany"\] You can provide up to 50 countries. The full list is available [here](https://waterfall-io-public.s3.us-east-1.amazonaws.com/waterfall_location_country.txt). #### location_name The `location_name` parameter represents the location of the contact's current address. Typical locations are: - `San Francisco, California, United States` - `Paris, Ile-De-France, France` A location can include city, region/state, and country. Partial matches are possible. Common partial formats are: - city, region: `San Francisco, California`, `Paris, Ile-De-France` - region, country: `California, United States`, `Ile-De-France, France` - city: `San Francisco`, `Paris` - region: `California`, `Ile-De-France` - country:`United States`, `France` In many cases, the best results are obtained using only the region. Empty values are ignored. --- # Errors The waterfall API uses conventional HTTP response codes to indicate the success or failure of a request, with detailed information in case of error. Error payload structure: - `category` is the high-level classification (`AUTH`, `VALIDATION`, `NOT_FOUND`, etc.). - `code` is the stable machine-readable identifier for a specific failure case. - Every `code` is namespaced by category using the format `CATEGORY_DETAIL` (for example `VALIDATION_BAD_REQUEST`). - The `category` field must always match the prefix of the `code` field. - Use `category` for broad handling (retry/auth/permissions) and `code` for precise logic and analytics. | Status Code | Description | | --- | --- | | 200 OK | The request was successful. | | 400 Bad Request | Your request was not valid. | | 401 Unauthorized | Missing API key. | | 403 Forbidden | Bad API key. | | 404 Not Found | The requested endpoint does not exist. | | 500 Internal Server Error | Something went wrong on our end. | --- # Contact Support Contact Support: Email: [felix@waterfall.io](https://mailto:felix@waterfall.io) termsOfService: https://www.waterfall.io/#FAQs contact: email: felix@waterfall.io servers: - url: https://api.waterfall.io description: The production API server security: [] tags: - name: prospector description: Prospector externalDocs: description: Prospector endpoint docs url: https://docs.waterfall.io/v1/prospector-launcher - name: enrichment-contact description: Enrichment Contact externalDocs: description: Contact enrichment endpoint docs url: https://docs.waterfall.io/v1/contact-enrichment-launcher - name: search-contact description: Search Contact externalDocs: description: Search Contact endpoint docs url: https://docs.waterfall.io/v1/search-contact-launcher - name: search-company description: Search Company externalDocs: description: Search Company endpoint docs url: https://docs.waterfall.io/v1/search-company-launcher - name: company-reveal description: Company Reveal - name: company-titles description: Company Titles - name: job-change description: Job Change externalDocs: description: Job Change endpoint docs url: https://docs.waterfall.io/v1/job-change-launcher - name: enrichment-phone description: Enrichment Phone externalDocs: description: Phone enrichment endpoint docs url: https://docs.waterfall.io/v1/phone-enrichment-launcher - name: enrichment-company description: Enrichment Company externalDocs: description: Company enrichment endpoint docs url: https://docs.waterfall.io/v1/company-enrichment-launcher - name: verify-email description: Verify Email externalDocs: description: Verify Email endpoint docs url: https://docs.waterfall.io/v1/email-verifier - name: account description: Account externalDocs: description: Account Reporter endpoint docs url: https://docs.waterfall.io/v1/account-reporter-v2 - name: api-keys description: Api Keys Management **Enterprise Feature** externalDocs: description: API key management endpoint docs url: https://docs.waterfall.io/v1/api-keys-overview - name: webhook-authentication description: Webhook Authentication externalDocs: description: Find out more about Waterfall API url: https://docs.waterfall.io/v1/introduction paths: /v1/job/change: get: tags: - job-change summary: Job Change Finder description: | Launch stage: Preview.
