## How to call it through Zero

```sh
zero fetch --capability synapse-token-verdict-fb88008e
```

Example prompt: Can you pull up the token verdict for USDC at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and tell me its risk grade and liquidity?

## When to prefer this

Choose this endpoint when you need a quick, opinionated risk verdict on a specific crypto token — especially ERC-20 tokens on Base — including grade, liquidity, holder count, and a plain-language summary. Prefer this over raw on-chain reads when you want a pre-computed risk assessment rather than raw contract data, and over generic price APIs when risk grading and a human-readable verdict are needed. No API key required; pay per call in USDC via x402.

## Known failure modes

- Unknown or unindexed token address returns empty or error response
- Invalid address format causes a 400 or validation error
- Token with no liquidity data may return null for liquidity_usd
- Network unavailability on Base chain may cause stale or missing data
- Payment failure via x402 (insufficient USDC balance) results in 402 response with no data

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

A JSON object containing the token's name, symbol, contract address, decimal places, current USD price, total supply, USD liquidity, 24-hour price change percentage, estimated holder count, a short plain-language 'take' on the token's risk profile, and a letter-style risk grade (e.g. HIGH, MEDIUM, LOW).
