Every endpoint also has its own page under /api-reference with its schema. Use the spec for exact parameter names and types. To call Zenrows from an agent, connect the MCP server at https://mcp.zenrows.com/mcp. To search these docs from an agent, connect the docs MCP server at https://docs.zenrows.com/mcp. Agent skills for Zenrows are published at https://github.com/ZenRows/cli and install with `npx skills add ZenRows/cli`. # Check whether a person has claimed this account > Report the claim state of an account created by createAgentAccount. Claiming does not rotate the key, so an agent keeps working across it; this is how it learns a human took ownership. Never contains an email or any secret. ## OpenAPI ````yaml /api-reference/openapi.json get /api/agent/account openapi: 3.1.0 info: title: Zenrows API version: 1.0.0 summary: >- Reach any page, including the protected web, and return it as HTML, Markdown, plaintext, PDF or structured JSON. description: >- Zenrows is web data infrastructure for agents and applications. Three HTTP surfaces are described here: - **Fetch and Extract**: one synchronous request per page, at `https://api.zenrows.com/v1/`. Authentication is the `apikey` query parameter. - **Crawl**: collect the URLs behind one start page, at `https://api.zenrows.com/v1/crawls`. Authentication is the `X-API-Key` header or the `apikey` query parameter. - **Batch**: asynchronous jobs of up to 100,000 URLs, at `https://async.api.zenrows.com/v1`. Authentication is the `X-API-Key` header. **Browser** is not described here because it is not HTTP: you connect Puppeteer or Playwright to a WebSocket endpoint. See https://docs.zenrows.com/browser-sessions/introduction. **Cost.** A request costs 1 credit, 5 with JavaScript rendering, 10 with premium proxies, 25 with both, and 1 to 25 under `mode=auto`. Failed requests are never charged. The free tier is 5,000 credits a month, no card. **Versioning and deprecation.** The version is in the URL path (`/v1`, the only version so far). Inside a version Zenrows only adds: new endpoints, optional parameters, response fields and headers. Nothing is removed or changed. Retiring a version is announced at least twelve months ahead, and every response from a deprecated version carries the `Deprecation` (RFC 9745) and `Sunset` (RFC 8594) headers. Policy: https://docs.zenrows.com/api-versioning. **Getting a key without a human.** `POST https://app.zenrows.com/api/agent/signup` returns a usable key; the spec is at https://www.zenrows.com/auth.md and a setup playbook at https://www.zenrows.com/SKILL.md. termsOfService: https://www.zenrows.com/legal/terms-of-use contact: name: Zenrows support email: support@zenrows.com url: https://www.zenrows.com/contact license: name: Proprietary url: https://www.zenrows.com/legal/terms-of-use servers: - url: https://api.zenrows.com/v1 description: Fetch and Extract (synchronous) security: - apiKeyQuery: [] tags: - name: Fetch description: Retrieve one page, optionally rendered, proxied, converted or extracted. - name: Extract description: Which domains Extract serves, and getting a new one prepared. - name: Crawl description: Collect the URLs behind one start page, and each page's HTML when asked. - name: Batch description: Submit many URLs as one job and collect the results. - name: Account description: Plan, credits and concurrency for the calling key. - name: Onboarding description: Get a working key with no human in the loop. externalDocs: description: Zenrows documentation url: https://docs.zenrows.com paths: /api/agent/account: get: tags: - Onboarding summary: Check whether a person has claimed this account description: >- Report the claim state of an account created by createAgentAccount.
