## 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 losbeto-llm-inference-gateway-x402-14b5bec4
```

Example prompt: Ask Losbeto's LLM gateway to summarize the following paragraph in 3 bullet points, limiting the response to 200 tokens: 'Central banks globally are tightening monetary policy in response to persistent inflation, raising concerns about a synchronized global recession.'

## When to prefer this

Choose this endpoint when an AI agent needs one-off or high-frequency LLM inference without managing provider API keys or subscriptions — especially useful for autonomous agents that pay micropayments in USDC on Base, Solana, or Algorand. Prefer this over hosted OpenAI/Groq directly when you want keyless, account-free access with flat per-call pricing and automatic provider failover.

## Known failure modes

- Payment not sent or insufficient USDC — returns HTTP 402 Payment Required
- max_tokens parameter missing or invalid — returns 400 Bad Request
- q (query) parameter missing — returns 400 Bad Request
- All upstream LLM providers unavailable — returns 503 or provider timeout
- USDC payment on unsupported chain — transaction not recognized, request rejected

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana and Algorand via x402.

## Output

A JSON response containing the LLM-generated text answer to the submitted query, produced by the first available provider in a Groq/Gemini failover chain, truncated to the requested max_tokens.
