How this service works
Factual directory of x402 pay-per-call services run by MoneyTools for AI agents, plus referral/affiliate links we hold. Contains referral links.
Output
A ranked JSON array of up to 3 x402 endpoint results, each containing the endpoint URL, a relevance score, liveness probe data (live boolean, latency in ms, uptime ratio), a precheck verdict (e.g. 'ok' or failure reason), and the price in USD.
Example use cases
Cheapest live x402 endpoint for web scraping
“Find me the best x402 endpoints for fetching and parsing web pages, filtered to under $0.01 each and running on Base — show me only ones that are live and have passed their 402 pre-check.”
Routing agent to right x402 API
“I'm building an agent that needs to translate text. Search the x402 catalogs and recommend the top 3 relevant endpoints, ranked by relevance score, that are live and OFAC-screened, with a max price of $0.05.”
Discovering x402 endpoints before committing payment
“Before I pay anything, can you find and pre-check x402 endpoints that can validate email addresses — I want to see their liveness, latency, and whether their payment terms are legitimate, all on the Base network.”
Technical details
Endpoint
GEThttps://api.moneytools.dev/v1/recommend?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to discover and vet x402-protocol paid API endpoints before committing to a payment. It is the right choice when you want relevance ranking plus live health checks and payment-term validation in a single call, rather than manually querying PayAI, Ultravioleta, or Dexter separately. Prefer it over static catalog lookups when endpoint liveness and OFAC compliance matter to your workflow.
Side effects
- No matching endpoints found for the given task description
- All candidate endpoints fail liveness probe — results returned with live:false
- maxPrice filter too restrictive — no endpoints under the specified price
- OFAC screen flags a payTo address — precheck verdict returns a non-ok status
- Invalid or missing task parameter — 400 error
- x402 payment not settled before request — 402 response returned
- Network filter yields no results for specified chain
