# fold · x402 — Qwen3-7-Max LLM Inference (Onchain Market Intelligence)

> fold · x402 — Qwen3-7-Max LLM Inference (Onchain Market Intelligence) is a paid API for AI agents from x402.fold.computer, paid per call via x402, $2/call, status down (last checked 2026-09-15).

Runs Qwen3-7-Max inference via x402 micropayment protocol, specialized for machine-readable onchain market intelligence queries from AI agents.

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 fold-x402-qwen3-7-max-llm-inference-onchain-market-intelligence-b465625b -d '<json body>'
```

Example prompt: Using fold's onchain market intelligence endpoint, ask: 'What are the current top performing DeFi protocols by TVL this week and what does the sentiment look like?' — pay $2 USDC per call, send it as an OpenAI-format user message.

## When to prefer this

Choose this endpoint when you need a Qwen3-7-Max LLM inference that natively accepts x402 micropayments in USDC, especially for onchain market intelligence tasks where you want machine-readable output suited for autonomous agent pipelines. Prefer this over generic LLM APIs when operating in a crypto-native or DeFi context where per-call stablecoin billing is required.

## Known failure modes

- Payment not included or insufficient — returns 402 Payment Required before inference runs
- Invalid messages array format — returns schema validation error
- Model timeout on very long context — may return incomplete completion
- Temperature or max_tokens out of acceptable range — parameter validation error
- Network or facilitator settlement failure — transaction may not complete

## How this service works

Machine-readable market intelligence for onchain agents, served over x402.

## Output

An OpenAI-format chat completion response containing the model's generated answer, along with x402 cost metadata including the USDC amount charged for the call and a status field confirming success.
