Overview
Parsium API (2.0.0)
Section titled “Parsium API (2.0.0)”Extract structured data from webpages with custom parsers or prebuilt APIs, then run work synchronously, in batches, on schedules, or as workflows.
Authentication
API endpoints accept an API key in the X-API-Key header (recommended) or the api_key query parameter. The public API catalog does not require authentication. MCP at POST /mcp also accepts Authorization: Bearer <api-key> and may support Clerk OAuth; /v1/* remains API-key only.
Credits and limits
Credit cost depends on the operation and scrape configuration. Scrape and prebuilt responses expose X-Credits-Used and X-Credits-Remaining. Use GET /v1/status for credits, reservations, class-specific concurrency, pending jobs, and active batches.
Errors and ownership
New endpoints return JSON error envelopes with error and optional field, detail, and hint. Resources not owned by the caller return 404, not 403. Validation failures return 422.
