Introduction - Seltz

The Seltz REST API gives AI agents and applications programmatic access to the Seltz platform over HTTPS and JSON. It covers five surfaces:

POST /v1/search — context retrieval over the web.
POST /v1/answer — RAG answers grounded in search results.
/v1/monitors — saved searches, re-run on a cadence, delivering only what is new. See Monitor for the guides.
POST /v1/fetch — URLs in, LLM-ready content out. See Fetch for the guides.
/v1/agent/runs — a multi-step research loop over the web, returning a cited answer. See Agent for the guides.

Streaming records is server-streaming gRPC and has no REST form. Use the interactive Endpoints pages in this section to explore each request and response and to send live requests with the built-in playground.

Authentication

Every request is authenticated with an API key passed in the x-api-key header. Create a key in the Seltz Console.

curl -X POST https://api.seltz.ai/v1/search \
  -H "x-api-key: $SELTZ_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "your search query"}'

OpenAPI specification

The full machine-readable spec is available at openapi.json — point your tooling or coding agent at it to generate clients or discover the surface.
