Horizon Pulse
GET https://horizonpulse.dev/api/search
Web search with page contents. Use when you need current information from the web with sources to cite. GET with required q (max 300 chars) and optional n (1-5 pages, default 3). Searches Google results via Serper, then fetches each top result as clean markdown. Returns JSON: results with rank, url, title, snippet, per-page ok/status and content (up to 12K chars each), plus resultCount and fetchedOk. Billed when at least one result returns; zero results or provider errors are not charged.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
