## 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 santyvv-data-token-info-on-chain-token-data-via-x402-f1d4cf1b
```

Example prompt: Look up the on-chain token info for the contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Base — I need the token name, symbol, and decimals.

## When to prefer this

Choose this endpoint when you need keyless, pay-per-call access to normalized on-chain token metadata without setting up API accounts or managing API keys. It is particularly suited for AI agents that need occasional token lookups billed directly in USDC via x402 on Base, and benefit from edge caching and multi-source fallback for reliability.

## Known failure modes

- Payment not received or invalid x402 USDC payment → 402 Payment Required
- Unknown or unsupported token contract address → empty or error response
- Network/chain not supported → error or null data
- Rate limit or upstream provider outage → 5xx or degraded response
- Malformed query parameters → 400 Bad Request

## How this service works

Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.

## Output

A normalized JSON object containing on-chain token metadata such as token name, symbol, decimals, contract address, and available market data fields sourced from public providers with edge caching and multi-source fallback.
