# STELQ
> Grounded web search, content extraction, answers, deep research, and standing monitors — as an API. Add STELQ to your product so your users get fresh, cited answers at runtime, and get told when things change.

Base URL: https://api.stelq.com
Auth: every request carries `Authorization: Bearer $STELQ_KEY`. Create a key in the STELQ console under API Keys.

## Services
- [Search](https://stelq.com/api/docs/search): Live web search on every request — never cached, never stale. Send a query, get back ranked results with titles, URLs and snippets. Synchronous: one request, one response. `POST https://api.stelq.com/v1/search/query`, $0.001/query.
- [Content](https://stelq.com/api/docs/content): Clean, structured extraction from any URL — Markdown and/or JSON, not HTML soup. Synchronous: one request, one response. `POST https://api.stelq.com/v1/content/extract`, $0.002/page.
- [Research](https://stelq.com/api/docs/research): Deep multi-source research jobs with resolving citations. Asynchronous: submit a job, get a handle back instantly, then poll (or take a webhook) until it's done. Most jobs finish in 5–15 minutes and read up to ~40 sources, returning a synthesized report plus the sources it stands on; a deep or source-heavy job can run longer. `POST https://api.stelq.com/v1/research/run`, from $0.08 (by depth)/job, asynchronous (submit → poll).
- [Answers](https://stelq.com/api/docs/answers): Grounded answers with citations, tuned for the agent loop. Ask a question, get a synthesized answer plus the sources it stands on. Synchronous: one request, one response. `POST https://api.stelq.com/v1/answers/ask`, $0.002/answer.
- [Monitors](https://stelq.com/api/docs/monitors): Standing watches on any topic. Describe what to watch in natural language; STELQ compiles it into diverse search queries, authoritative domains, a per-topic significance rubric and direct sources (feeds, JSON endpoints, high-signal pages — each confirmed by a live fetch). The first check establishes a baseline; every later check on the cadence you chose is recorded and badged minor / notable / major against it, with a summary and the new items. Price follows size: $0.05 to create per block of 12 queries, $0.01 per check per block — preview both with a free plan call before you pay. `POST https://api.stelq.com/v1/monitors/create`, $0.05/monitor per block of 12 queries, then $0.01 per check per block, standing — create once, checks run on a cadence; read events back or take a webhook.
