## 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 agnic-ai-9ffbda7e -d '<json body>'
```

Example prompt: Process an x402 payment for my AI agent using Agnic so it can access a paid service — the agent identity is 'agent-7f2a' and the payment should be authorized in USDC.

## When to prefer this

Choose this endpoint when you need to combine AI agent identity management with x402-protocol micropayments in a single call, especially when building monetized agent pipelines or agent-to-agent payment flows on Coinbase-ecosystem infrastructure.

## Known failure modes

- Insufficient USDC balance — payment rejected
- Invalid agent identity credentials — authentication failure
- Malformed x402 payment request — 400 bad request
- Payment already processed (duplicate) — idempotency conflict
- Network or blockchain congestion — timeout or delay

## How this service works

Identity, x402 powered payments, and monetization for AI agents.

## Output

Returns a payment confirmation or authorization token indicating whether the x402 payment was successfully processed, along with any identity or monetization metadata for the agent.
