How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a count of matching results, an array of result entries matching the capability query (based on Delx-owned probe receipts), the echoed capability query string, and a disclaimer noting that results are observations rather than endorsements.
Example use cases
Agent capability discovery at runtime
“Search the Delx verified directory for any APIs that can do email sending — I need to find a verified, pay-per-result option my agent can call right now.”
Exploring verified web scraping tools
“Look up 'web scraping' in the Delx verified directory and tell me what probed services show up.”
Finding verified payment-capable APIs
“Query the Delx verified directory for APIs with payment processing capability and list the results with their details.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/verified-directory?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically discover verified, Delx-probed APIs by capability keyword at runtime, especially when operating in a pay-per-result, no-signup environment using x402/USDC payments. Prefer this over broader API marketplaces when you need verifiable delivery guarantees and on-chain payment provenance.
Side effects
- Empty results array if no Delx-probed APIs match the capability query
- Payment failure or 402 response if USDC payment via x402 is not properly submitted
- Capability string exceeding 120 characters rejected by schema validation
- Malformed request body returns validation error
- Network or blockchain payment settlement delay causing timeout
