## 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-openapi-summary-fetcher-c8fc833c -d '<json body>'
```

Example prompt: Can you fetch and summarize the OpenAPI spec at https://commerce.delx.ai/openapi.json and tell me the title, version, how many paths it has, and what auth methods it uses? Use a 10-second timeout.

## When to prefer this

Use this endpoint when an AI agent needs a quick, structured summary of an OpenAPI specification from a URL without downloading and parsing the full document itself — especially useful for discovering x402-payment-gated paths. Prefer it over manual OpenAPI parsing when you want a lightweight, pay-per-use tool with no signup or API key required.

## Known failure modes

- Timeout exceeded if the target URL does not respond within the specified timeout window
- Invalid or unreachable URL returns an error
- Non-OpenAPI URL may return malformed or empty result
- Payment failure if USDC balance is insufficient for the $0.001 fee
- Rate limiting or access restrictions on the target OpenAPI URL
