## 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 base-token-market-and-security-snapshot-api-99c02525
```

Example prompt: Can you pull the market data and security snapshot for the Base token at address 0x4200000000000000000000000000000000000006 — I want to see the contract metadata and any third-party security flags?

## When to prefer this

Choose this endpoint when you need a combined, single-call snapshot of market data, contract metadata, and security signals specifically for tokens on the Base (Coinbase L2) network. It is ideal for due diligence workflows, DeFi trading safety checks, or token listing reviews where you need both financial and security data in one request without aggregating multiple sources yourself.

## Known failure modes

- Invalid or malformed contract address (not matching 0x[40 hex chars] pattern) returns a validation error
- Contract address does not exist on Base network returns empty or not-found response
- Payment failure or insufficient USDC balance returns a 402 Payment Required error
- Rate limiting or upstream data provider outage may return 503 or timeout
- Token exists but has no market data yet (newly deployed) may return partial results

## How this service works

A pay-per-request snapshot of Base ERC-20 market data, contract metadata, and third-party security signals.

## Output

A JSON snapshot containing Base ERC-20 market data (price, liquidity, market cap), contract metadata (name, symbol, decimals, deployer), and third-party security signals (risk scores, audit flags, honeypot detection) for the requested token address.
