## 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-approval-route-api-144565c5 -d '<json body>'
```

Example prompt: I need to make a $250 payment that's been flagged as high risk — can you tell me which approval route I should use and whether a human needs to sign off on it?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically determine the correct approval workflow for a transaction or action based on risk and amount, especially in agentic pipelines where spend governance and human-in-the-loop decisions must be automated. Prefer this over hardcoded routing logic when risk levels and amounts vary dynamically and you want a verifiable, pay-per-result determination with no signup overhead. Best suited for agents managing financial actions that must comply with authorization policies.

## Known failure modes

- Missing required fields (risk or amount) — likely returns a 4xx validation error
- Invalid risk value not matching expected enum — may return an error or fallback route
- Payment failure via x402 — 402 response if USDC payment not included or insufficient
- Service unavailable — 5xx response if backend is down
- Ambiguous or borderline risk/amount combinations may produce unexpected routing recommendations

## 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 containing the original risk level and amount, the recommended approval_route string (e.g., 'security_and_finance'), a boolean human_required flag indicating whether human review is needed, an advisory message reminding the caller they remain responsible for their own authorization policy, and a schema identifier (e.g., 'delx/util-approval-route/v1').
