## 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 onchain-trading-intelligence-130-multichain-tools-x402-pay-per-call-ab7485e3 -d '<json body>'
```

Example prompt: Check whether the token at contract 0xABC...123 on Ethereum is a honeypot or rug pull, and give me its current price, liquidity, and any OFAC sanctions flags — I need this before I consider buying.

## When to prefer this

Choose this endpoint when your AI agent needs real-time, pay-per-call onchain and trading intelligence without committing to API keys or subscriptions — especially for multichain token safety screening, DeFi risk assessment, perpetuals/options analytics, or Robinhood Chain tokenized-equity intelligence. Prefer it over general blockchain explorers when you need composited risk signals (honeypot + OFAC + wallet reputation) or cross-venue derivatives data in a single call settled in stablecoins.

## Known failure modes

- Invalid or unreachable URL returns an error response
- Insufficient stablecoin payment results in 402 Payment Required
- Chain or contract not supported returns empty or error payload
- Rate limiting or upstream data source outage causes delayed or missing data
- Malformed URL input fails schema validation

## How this service works

Fetch any public web page and return clean, LLM-ready markdown (plus title and final URL). Send { url }. We handle fetching, redirects, and noise-stripping.

## Output

Returns structured JSON containing the requested intelligence for the queried URL endpoint — which may include token prices, risk scores, sanctions flags, funding rates, options greeks, wallet reputation metrics, PnL figures, or tokenized-stock dislocation data depending on which of the 130 tool URLs was called.
