## 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 bitcoin-benji-ai-agent-inference-be66a5ae -d '<json body>'
```

Example prompt: Run an AI inference query for me using Bitcoin Benji's Lightning-gated API — I want to ask it 'What is the current sentiment in the Bitcoin market?' and pay the per-call fee automatically via Lightning.

## When to prefer this

Choose this endpoint when you need AI inference without API key registration or subscription overhead, want to pay strictly per call using Bitcoin Lightning micropayments, require privacy-preserving AI access with no account linkage, or are building Bitcoin-native agent workflows where x402/L402 payment is already supported in your stack.

## Known failure modes

- Invalid or malformed prompt body — returns 400 Bad Request
- Inference timeout on the model backend — returns 504 or timeout error
- Insufficient payment amount — L402 challenge returned without fulfilling request
- Network unavailability of Lightning payment endpoint — connection failure
