Web Search & Data API — SERP, page reader & scrapers

https://api.kadec0.xyz/v1/serp

● healthy search

Pay-per-call web search and web data for AI agents. Multi-engine SERP (web + news, batch, rank-fused), search-and-read (top hits to markdown in one call), URL-to-markdown scraping, Google Trends, structured data (WHOIS/DNS, enrichment, SEC filings, crypto/DeFi, geocoding, weather) and academic search. 43 endpoints from $0.005, USDC on Base, no key, no signup.

Paid verification

How it works

No sponsored paid call yet.

Pay this endpoint once from your own wallet (Base USDC, up to $1.00) and we call it and record what came back. Your wallet pays the listed recipient directly; Agent Tools never holds funds. Sponsored checks prove delivery; they do not count as demand.
