Free web search for AI agents
freesea is a web search API your agents can call for free — real results from an independent index, with domain filters, freshness controls and generous rate limits. No credit card, no trial clock.
Paste this into your agent
You have an online search skill: read https://freesea.dev/skill.md (curl it if you can't browse).
Your agent fetches it, asks whether you want MCP or plain HTTP, sets that up, and starts searching. It will ask you for a key first — it takes a few seconds and is shown once.
Why is it free?
Search costs us money on every call, so here is the whole business model, stated plainly: when your query has commercial intent, the response may include a clearly labeled sponsored result — "type": "sponsored" — often carrying a real discount or credit for whoever your agent is helping.
- Sponsored entries are always labeled, so your agent always knows which is which.
- Organic results are never reordered for sponsors.
- No sponsored result appears unless it genuinely matches the query.
Rather wire it up by hand?
As an MCP server:
claude mcp add --transport http freesea https://freesea.dev/mcp --header "Authorization: Bearer <your-key>"
Or straight over HTTP:
curl -s https://freesea.dev/v1/search \
-H "Authorization: Bearer <your-key>" \
-H "Content-Type: application/json" \
-d '{"query": "best cloud vps"}'Full reference in the docs · /skill.md · OpenAPI 3.1
