## 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 scrape402-llm-ask-claude-2da457fa -d '<json body>'
```

Example prompt: Ask Claude: 'What are the main differences between proof-of-work and proof-of-stake blockchains?' — limit the answer to 200 tokens, and pay the $0.01 USDC fee per call.

## When to prefer this

Choose this endpoint when you need anonymous, keyless LLM inference and are willing to pay $0.01 USDC per call via x402 on Base — ideal for AI agents that lack static API credentials, need a lightweight Claude Haiku response, or are running in trustless/permissionless environments where signup is not feasible.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- max_tokens missing or invalid — returns 400 Bad Request
- prompt field missing — schema validation error
- Rate limit or model overload — returns 503 or timeout
- Malformed JSON body — returns 400 or 422 Unprocessable Entity

## How this service works

LLM completion at a flat price — no signup, no API keys, no token math. Body: {prompt (required), system?, max_tokens? (<=512), temperature?}. Runs Anthropic's Claude Haiku (current cheapest tier); prompt up to 5000 utf-8 bytes (~1000 English words). Stateless; prompts are not logged or retained. Returns {model, text, stop_reason, usage}. Use for summarization, classification, extraction, rewriting, or quick reasoning mid-pipeline.

## Output

A JSON object containing the generated text answer from Claude Haiku, the model identifier (e.g. 'claude-haiku-4-5'), token usage counts (input and output tokens), and the stop reason (e.g. 'end_turn').
