## 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 mistral-ai-via-locus-x402-list-models-59598f7d -d '<json body>'
```

Example prompt: Show me all the Mistral AI models available through the Locus x402 gateway so I can pick the right one for my task.

## When to prefer this

Use this endpoint when you need to programmatically discover which Mistral AI models are available through the Locus x402 micropayment gateway before making a generation or embedding call. Prefer this over calling Mistral's native API directly when you want pay-per-call USDC billing without managing API keys, or when operating inside an x402-compatible agent framework.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment header missing/malformed
- Network timeout reaching the Locus gateway
- Upstream Mistral API unavailability causing empty or error response
- Invalid body type enum value causing schema validation error
- Non-POST method returns method-not-allowed error

## How this service works

Locus public pay-per-use API
