## 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 jarvisclaw-ai-api-gateway-marketplace-endpoint-521-469cc5a6 -d '<json body>'
```

Example prompt: Send my query to the JarvisClaw marketplace endpoint 521 and pay per call in USDC — I want to ask it: 'Summarize the key benefits of using a smart-routing AI gateway.'

## When to prefer this

Choose this endpoint when you need pay-per-call AI inference with no subscription or API key management, when your agent supports x402 micropayments settled in USDC on Base or Solana, and when you want OpenAI-compatible responses via a marketplace-listed gateway. It is well-suited for sporadic or bursty AI workloads where per-call billing is more cost-effective than a flat-rate plan.

## Known failure modes

- Insufficient USDC balance causes x402 payment failure and request rejection
- Invalid or missing query parameter returns a 400 bad request
- Gateway routing failure if no suitable downstream model is available
- Network timeout on slow or complex queries
- Unsupported query format may yield malformed or empty response

## How this service works
