Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 desk-lead-x402-memecoin-score-51e1340f
```

Example prompt: Can you score the memecoin at contract address 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed and tell me its risk flags and overall score?

## When to prefer this

Use this endpoint when you need a fast, quantified risk score for a specific memecoin token contract and want structured flag data alongside the score. Prefer this over general blockchain explorers when you need a single actionable score rather than raw on-chain data, and when you are willing to pay $1 USDC per lookup via x402 micropayment on Base.

## Known failure modes

- Invalid or malformed token address (not a valid 0x EVM address) returns an error
- Token address not found or not recognized as a token contract
- Payment not provided or invalid — endpoint requires $1 USDC via x402 v2 on Base (eip155:8453)
- Network mismatch — primary v2 only accepts Base; using wrong chain may fail
- Rate limiting or worker timeout on the Cloudflare Workers backend

## How this service works

Micropay research APIs (x402 v2 + bazaar). Free catalog at /.well-known/x402.json. Primary v2 accepts: Base eip155:8453 only. Legacy X-PAYMENT-TX still supports bsc|base via acceptsV1. Headers: X-PAYMENT-TX, X-PAYMENT-NETWORK, PAYMENT-SIGNATURE. No financial advice.

## Output

Returns a JSON object with an 'ok' boolean, a 'product' field ('memecoin_score'), and a 'report' object containing a numeric 'score' (e.g. 42) and an array of 'flags' listing any identified risk signals for the token.
