## 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 x402-agent-escrow-0fd9fc41 -d '<json body>'
```

Example prompt: Check whether my agent is allowed to make a GET request through the x402 escrow system and give me the approval result after payment settles.

## When to prefer this

Use this endpoint when an AI agent needs to gate a read-only or destructive HTTP action (GET, HEAD, DELETE) behind an escrow and payment-authorization layer using the x402 protocol. It is most appropriate for agent fleet infrastructure scenarios where spending limits and action approval must be enforced before a request proceeds, rather than just checking limits passively.

## Known failure modes

- Payment not settled — returns 402 with payment-required details
- Invalid HTTP method supplied (only GET, HEAD, DELETE accepted) — validation error
- Missing required 'type' or 'method' fields — schema validation failure
- Escrow condition not met — allowed returns false with summary explanation
- Network or Railway deployment downtime — connection error

## How this service works

24 paid x402 infrastructure APIs for AI agent fleets: buy advisor, audition coach, guard, proxy, MPP, attestations, and pipeline orchestration.

## Output

Returns a JSON object with 'ok' (boolean indicating request success), 'allowed' (boolean indicating whether the action is permitted), and 'summary' (a plain-text explanation of the escrow decision after x402 payment settlement).
