## 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 clawy-pay-per-call-ai-inference-x402-usdc-on-base-77b5686c -d '<json body>'
```

Example prompt: Send this message to an AI model and get a response right now — pay the micro USDC fee automatically: 'Summarize the key risks of investing in early-stage startups in three bullet points.'

## When to prefer this

Choose Clawy when you need one-off or low-volume LLM inference without committing to a subscription or storing API keys — particularly in autonomous agent pipelines that already handle x402 USDC micropayments on Base. It is ideal when you want cost-per-call billing at $0.02–$0.05 USDC and access to both OpenAI and Anthropic models behind a single endpoint with automatic routing.

## Known failure modes

- HTTP 402 returned if the x402 payment header is missing or the USDC balance is insufficient
- Payment settlement timeout on Base can cause delayed or failed responses
- Model routing ('auto') may select a provider that is temporarily unavailable, causing a 503
- Malformed messages array will result in a 400 bad request
- Rate limiting may apply if too many concurrent calls are made from the same wallet

## How this service works

HTTP-402 gated ChatGPT and Claude Opus inference. $0.02–$0.05 USDC per call, settled in &lt;2s on Base via the x402 protocol. No API keys, no signup, no subscriptions.

## Output

A JSON chat completion object mirroring the OpenAI ChatCompletion schema, including the assistant's message content, finish reason, model name ('auto'), and an extra `x_clawy` field indicating which provider (e.g. 'anthropic') and delivery method (e.g. 'claude-cli') was used. Payment is settled on Base in under 2 seconds via the x402 protocol before the response is returned.
