How this service works
Pay-per-call web tools for AI agents. No signup, no API key: pay USDC on Base or Solana per request via x402.
Output

Example use cases
GitHub API endpoint discovery
“I need to find the right GitHub API endpoint to list pull requests for a repo — can you look it up using Agent Tools and tell me the URL path and spec?”
Stripe payment API lookup
“Find the correct Stripe API endpoint for creating a payment intent — search the Stripe spec for 'create payment intent' and return the matching endpoint and base URL.”
Shopify product search endpoint
“What's the Shopify API endpoint for searching products by title? Use Agent Tools to look it up against the Shopify spec and give me the matched paths.”
Technical details
Endpoint
POSThttps://agent-tools.faling-bot.workers.dev/api/api-endpoint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover the correct API path to call for a given task, without hardcoding endpoint URLs. Ideal for agents orchestrating calls across multiple APIs or working with unfamiliar APIs at runtime. Requires no signup or API key — only a USDC micropayment on Base or Solana via x402.
Side effects
- No matching endpoints found if the query is too vague or the API name is not recognized
- Payment failure if the x402 USDC microtransaction is not completed correctly
- Invalid or unreachable spec_url causes lookup failure
- Ambiguous query returns too many or irrelevant endpoint matches
