## 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-6dc1591e -d '<json body>'
```

Example prompt: Check whether this token on Solana is a honeypot or rug pull, and give me its current price and liquidity — here's the raw HTML from the token page.

## When to prefer this

Choose this endpoint when you need pay-per-call, no-subscription on-chain and trading intelligence without API key management, especially for multichain token safety checks, Solana memecoin sniping, perp/options analytics, or Robinhood Chain tokenized stock analysis. Prefer it over centralized data providers when you need OFAC screening, honeypot detection, and funding arbitrage data in a single call settled in stablecoins on Base, Polygon, Arbitrum, or Solana.

## Known failure modes

- Missing or empty 'html' field returns a 400 validation error
- Malformed or non-trading HTML yields empty or low-confidence extractions
- Payment failure via x402 protocol blocks the call with a 402 response
- Rate limits or Railway infrastructure downtime returns 5xx errors
- HTML from unsupported chains or protocols may return partial or null fields

## How this service works

Extract structured data (title, links, meta, headings, text) from HTML as JSON.

## Output

A structured extraction of on-chain or trading intelligence from the submitted HTML, which may include token price, liquidity depth, honeypot/rug detection verdict, OFAC sanctions flag, wallet risk score, PnL data, perp funding rates, open interest, options greeks, DeFi lending health metrics, MEV risk signals, or Robinhood Chain tokenized-stock analytics — depending on the HTML content provided.
