## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-verified-directory-search-dd4119f5 -d '<json body>'
```

Example prompt: Search the Delx verified directory for APIs that can handle DNS lookups and show me what comes back.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
