The same pipeline that runs financial analysis across 5,800 US equities every trading day. Uptime isn't optional for us either.

Your agent hits a search API, gets 10 blue links, scrapes each one, strips the HTML, stuffs it into a prompt, runs the LLM, parses the output... and you pay for every token of that chain. For every single user query. That's not an integration — it's a full-time job.

The Difference

We do the research. You get the answer.

FlatSearch is a managed research sub-agent. Send a question, and we scrape live sources, strip the noise, cross-reference findings, and return a structured JSON answer with cited sources — ready to inject into your agent's context window or return directly to your user.

Real Example

What your agent gets back. 2.1 seconds. $0.001.

Request
curl https://flatsearchapi.com/v1/search/fast \
  -H "X-API-Key: sp_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "Next.js 15 iron-session ERR_TOO_MANY_REDIRECTS on Vercel with subdomains"}'
Response
{
  "answer": "The ERR_TOO_MANY_REDIRECTS error occurs because cookie storage defaults to the parent domain. Fix: set cookieOptions.domain = '.yourdomain.com' in your session config...",
  "sources": [{ "title": "iron-session #521", "url": "https://github.com/vvo/iron-session/issues/521", "snippet": "Adding domain resolved redirect loops across subdomains..." }],
  "response_time_seconds": 2.12,
  "tier": "fast"
}
Not a list of blue links. A finished answer your agent can use immediately — or pass directly to the end user.
