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
Returns a structured profile including: the seller's Bazaar record (number of endpoints, 30-day call and unique payer counts, estimated revenue, price range, timestamp of last call), a list of other hosts sharing the same payTo wallet, and flags for temporary-tunnel detection and price anomalies. Data is public and informational — signals to inform a payment decision, not a definitive verdict.
Example use cases
Pre-payment due diligence on unknown API
“I found an x402 API at https://api.someservice.dev/v1/data that wants $0.01 per call — can you pull its Bazaar record and tell me how many unique payers it has had in the last 30 days and whether there are any tunnel or price warnings before I let my agent pay?”
Wallet co-usage investigation
“This x402 seller wallet 0xABCD1234... seems to be used by multiple different endpoints — can you look it up and show me all the other hosts that are paying to the same wallet address?”
Automated seller screening before agent deployment
“I'm about to deploy an agent that will automatically pay x402 APIs — can you check the seller at https://data-provider.workers.dev/endpoint and give me its revenue estimate, call volume, and any red flags like temporary tunnels or unusual pricing?”
Technical details
Endpoint
GEThttps://agent-data.centorprat.workers.dev/agent/seller-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent is about to make an x402 micropayment and needs a quick trust signal about the seller before committing funds. It is the right choice when you have an endpoint URL, host, or payTo wallet address and want Bazaar-sourced statistics (call volume, payer count, revenue) plus co-wallet and tunnel warnings. Prefer this over generic blockchain lookups when the seller operates in the x402 ecosystem and you want marketplace-specific social proof and pricing context.
Side effects
- URL or wallet address not found in Bazaar — returns empty or null record
- Invalid input format (non-URL, non-address string) — may return error or empty result
- Seller is new with no Bazaar history — all stats will be zero or missing
- Temporary tunnel domain not resolvable at time of check — warning flag set but data may be incomplete
- Rate limiting or upstream Bazaar API unavailability — may return stale or partial data
