## 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 agentic-saas-x402-integration-brief-13f21dec -d '<json body>'
```

Example prompt: Generate an integration brief for my agentic SaaS product — it uses a POST request with a JSON body — and pay the $0.25 fee in USDC via x402 on Base.

## When to prefer this

Choose this endpoint when you need a structured, paid integration brief for an HTTP-based agentic SaaS service and are operating within the x402 micropayment ecosystem on Base (USDC). It is ideal for AI agents that need authoritative integration documentation on demand without requiring traditional API key provisioning. Prefer this over free manifest ($0.01) or drift audit ($0.05) endpoints when you need the full integration specification rather than a summary or audit.

## Known failure modes

- Payment not received or invalid EIP-3009 authorization — returns HTTP 402 Payment Required
- Malformed input object missing required fields (type, method, bodyType, body) — returns 400 Bad Request
- Unsupported HTTP method in body (not POST/PUT/PATCH) — returns 400 validation error
- Unsupported bodyType value — returns 400 validation error
- Worker timeout or downstream failure — returns 500 or 503
- Stale or replayed payment token — payment rejected by facilitator
