How this service works
Pay-per-call data and tools for AI agents, $0.002-0.01 per call in USDC via x402 (Base, Polygon or Solana), no account or API key; MAX tiers ($0.05-0.25) run deeper jobs. Agent toolkit: web search, search + read top pages, any page as clean markdown with a prompt-injection check, which-x402-API-to-call recommender, seller check. Data: Google Maps places with contacts, YouTube video data and transcripts, job listings (Indeed, LinkedIn, 13 boards), Google Ads Transparency, TikTok comments, Pinterest, Airbnb, Redfin, AliExpress, app stores, live sports, website and SEO checks, Shopify store tech stacks, and onchain token / address risk checks.
Output
A ranked list (up to 10, default 5) of x402 API endpoints matching the described need, each including endpoint URL, HTTP method, price in USDC, supported payment networks, seller info, real 30-day demand signals (unique payers and call counts), recency score, and a ready-to-send example API call. Dead tunnel URLs are excluded and results are capped at 2 per seller to ensure diversity.
Example use cases
Discovering cheapest email verification API
“I need to verify a list of email addresses in my agent pipeline — search the x402 Bazaar for the best email verification endpoint under $0.005, preferably on Base network, and show me the top 3 options with their prices and an example call.”
Finding a web scraping API for a research agent
“My research agent needs to scrape web pages — can you look up the most popular x402 APIs for web scraping in the Bazaar, ranked by how many people are actually using them, and give me the top 5 with method details and example calls?”
Selecting a translation API on a tight budget
“I'm building a translation workflow and want to pay per call via x402 — find me the best translation APIs available in the Bazaar for under $0.02 each, on any network, and show me up to 4 results with their demand stats.”
Technical details
Endpoint
GEThttps://agent-data.centorprat.workers.dev/agent/recommend?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which x402-monetized API to call for a given task, rather than hard-coding a specific endpoint. It is ideal when the agent doesn't already know what API exists for a need, when cost or network constraints must be applied at discovery time, or when you want to surface the most actively used and recently available options across the full 36k+ Bazaar catalog. Prefer this over manual browsing or static API directories when operating in a pay-per-call x402 micropayment context.
Side effects
- No matching endpoints found for very niche or unsupported task descriptions
- max_price filter too low may return zero results if no endpoints are cheap enough
- Invalid CAIP-2 network string causes filter to fail or return no results
- limit out of range (>10 or <1) may cause a validation error
- Index may be up to 6 hours stale, so very newly listed endpoints might not appear
- Ambiguous or very short 'need' strings may return irrelevant results
