## 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 tarnak-x402-toolkit-llm-chat-completions-abliterated-model-21796df0 -d '<json body>'
```

Example prompt: Generate a chat completion using an abliterated local LLM — send it the message 'Explain how smart contracts work in two sentences' with max 200 tokens and pay per token via USDC on Base, no API key needed.

## When to prefer this

Choose this endpoint when you need a keyless, no-signup LLM chat completion paid per-call in USDC on Base via x402 protocol, especially if you want an abliterated (uncensored) open-weight model and are building crypto-native or autonomous agent workflows that cannot hold traditional API keys.

## Known failure modes

- Payment not received or x402 flow fails — returns 402 Payment Required
- Messages array missing required role/content fields — returns 400 Bad Request
- max_tokens exceeds 1000 — rejected by schema validation
- Model alias ignored; server always uses its local abliterated model regardless of input
- IP rate-limited after 10 free verdicts per day — returns 429 Too Many Requests
- Server unavailable or local model not loaded — returns 503

## How this service works

Keyless pay-per-call APIs for AI agents on Base: token risk verdict, rug/honeypot report, gas estimate, URL-to-markdown and more. x402 v2, USDC, no API key or signup. 10 free verdicts per IP per day.

## Output

Returns an OpenAI-compatible chat.completion JSON object containing the assistant's message text, token usage breakdown (prompt, completion, total), billing details (USD charged, unit price, blocks), model name, and finish reason.
