## 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 saylor-innovations-watchdog-api-coin-dossier-3e362ca7
```

Example prompt: Pull a full Watchdog dossier on the Solana token at mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v — I want to see the risk verdict, who can mint or freeze it, any sanctions hits, top holders, and the 30-day price history.

## When to prefer this

Choose this endpoint when you need a single, comprehensive risk and due-diligence report on a specific token — especially when you need on-chain control information (mint/freeze/clawback authorities), sanctions screening, creator provenance, and price history in one call across 70+ chains. Prefer it over generic block explorer APIs when you want a pre-scored risk verdict and checklist rather than raw chain data. Also preferable when evaluating tokens for DeFi protocol listing, exchange onboarding, or personal investment decisions.

## Known failure modes

- Unknown or unsupported token address returns an error or empty result
- Ambiguous address existing on multiple chains requires the optional `chain` parameter — omitting it may return wrong-chain data
- Algorand asset IDs and Cosmos denoms require the `chain` query param or the call will fail
- Payment failure (x402) if USDC balance is insufficient — returns 402 Payment Required
- Rate limiting or upstream data gaps may result in partial data (e.g. missing price history for very new tokens)
- Malformed mint address format returns a validation error

## How this service works

Complete coin dossier on 70+ chains - verdict, who can mint, freeze or claw back, creator history, sanctions, holders, 30-day price history and a checklist.

## Output

A structured JSON object containing: token name, symbol, and address; chain identifier; risk verdict with ranked evidence-bearing flags, critical/high counts, copycat check, price impact estimates, and score reasons; on-chain controls (who can mint, freeze, or claw back); creator history; sanctions screening results; top holder distribution; 30-day price history; market data (price, 24h change, liquidity, volume, market cap, FDV, buy/sell counts, pool info, age); block explorer and social links; and a safety checklist with contextual notes.
