## 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-ai-chat-7621f932 -d '<json body>'
```

Example prompt: Ask ManyLives AI using the llama-3.3-70b model: in one sentence, what is a Sharpe ratio and why does it matter for evaluating a crypto trading strategy?

## When to prefer this

Choose this endpoint when you need a pay-per-call LLM chat completion with no account or subscription, particularly for trading or crypto-domain questions. It is well-suited for AI agent pipelines that need to invoke an LLM occasionally without committing to a monthly plan, paying only $0.005 USDC per call via x402. Prefer it over OpenAI or Anthropic endpoints when you want a lightweight, permissionless, crypto-native inference call using Llama models.

## Known failure modes

- Payment not sent or insufficient USDC — 402 response blocking the call
- Prompt exceeds allowed context or max_tokens set above 1024 — truncation or error
- Invalid messages array format — server may reject or misparse the conversation
- Model name misspelled or unsupported — falls back to default or errors
- Temperature outside 0–1.5 range — may be clamped or rejected

## 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

A JSON object containing the model name used, a text reply from the LLM, and usage metadata including max_tokens and input character count.
