Send a URL and get back clean Markdown, the page's own structured data, schema-shaped JSON, links, or a summary, with the navigation, banners and boilerplate stripped out. Scrape one page, crawl a whole site, run a search, or extract to a schema, all through one API with one response shape. Every call costs one credit a page whatever it took to fetch, and failures are never billed. Point us at a whole site and get every page. Ask a question and get answers with per-field confidence and the passage each value came from. You describe the outcome you want — the pipeline decides how to get it. ## Authentication Every request is authenticated with your API key in the `X-API-Key` header. Keys are scoped to a workspace and carry its credit balance. ## Credits Calls are billed in credits and charged only on success. A standard scrape is one credit; richer formats and the extraction tier cost more. Each response reports what it consumed. ## Conventions All timestamps are UTC ISO 8601. Long-running jobs (crawl, batch) return a job id you poll, or a webhook you register. ## Errors Every failure returns the same shape, whatever the status: ```json { "success": false, "error": { "code": "INSUFFICIENT_CREDITS", "message": "Insufficient credits" }, "meta": { "requestId": "019e8a3c-9f0b-7c12-88ab-1d2e3f4a5b6c" } } ``` Branch on `error.code`, which is stable. `error.message` is written for a person and may be reworded without notice. Validation failures add `error.details`. Quote `meta.requestId` when asking us about a specific failure. Every operation documents the codes it can return. ## Rate limits Limits are per workspace, not per key, over a 60 second window, and the ceiling comes from your plan. Every response carries the IETF RateLimit header fields so you can self-throttle rather than discovering the limit by hitting it: ```http RateLimit-Policy: "workspace";q=600;w=60 RateLimit: "workspace";r=599;t=42 ``` `q` is the quota, `w` the window in seconds, `r` the requests remaining and `t` the seconds until the window resets. A 429 also carries `Retry-After` in seconds; wait that long rather than retrying immediately. The older `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset` headers are still sent and mean the same thing. ## Versioning and deprecation The version is in the path: every endpoint on this API lives under `/v1/`. Within a version we only make additive changes — new endpoints, new optional parameters, new fields in a response. Adding a field to a response is not a breaking change, so parse defensively and ignore what you do not recognise. Anything that would break an existing integration ships under a new version path instead. When an endpoint or a version is retired, the responses say so before it stops working: ```http Deprecation: @1780272000 Sunset: Sat, 01 May 2027 00:00:00 GMT Link: ; rel="deprecation" ``` `Deprecation` (RFC 9745) marks when the endpoint became deprecated, `Sunset` (RFC 8594) when it stops responding, and the `deprecation` link relation points at what to move to. Nothing on this API is deprecated today, so you will not see these headers yet. Watch for them rather than for an announcement: the headers are the notice, and the linked changelog carries what to move to. version: '1.0' contact: name: Hydrafetch url: https://hydrafetch.com email: support@hydrafetch.com servers: - url: https://api.hydrafetch.com description: Production security: - apiKey: [] tags: - name: Scrape description: >- Turn one URL into clean, LLM-ready content.
