Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 manylives-llm-chat-completions-trading-aware-34f36174 -d '<json body>'
```

Example prompt: Ask the ManyLives trading AI to explain what a Sharpe ratio above 2.0 means for a crypto strategy's risk-adjusted performance — use the 70b model and keep the answer under 100 tokens.

## When to prefer this

Choose this endpoint when you need a pay-per-call, no-account LLM that is purpose-built for trading agent workflows and integrates with ManyLives' ecosystem of backtests, track records, and on-chain tools via the x402 micropayment protocol — ideal for AI agents that need to reason about financial strategies without a subscription.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 requiring x402 payment
- Invalid or missing messages array — returns 400 bad request
- max_tokens exceeds 1024 — may be clamped or rejected
- Temperature outside 0–1.5 range — may be rejected or clamped
- Model name not recognized — defaults to llama-3.3-70b or errors
- Network timeout if prompt is very long

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

Returns an OpenAI-compatible chat completion JSON object containing the assistant's reply text, the model used, token counts (prompt, completion, total), finish reason, and a completion ID — identical in structure to standard OpenAI chat completions responses.
