## 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 iamrich402-wallet-999-99-flex-checker-af54824f
```

Example prompt: Has the wallet 0x1234abcd...5678 ever sent exactly $999.99 in USDC? I want to know if it qualifies as 'rich' with on-chain proof.

## When to prefer this

Use this endpoint when you specifically need to verify whether a single wallet has ever made a $999.99 USDC on-chain transfer and want a simple rich/not-rich verdict with a transaction proof link. It is a novelty/gated flex-checker, not a general-purpose blockchain explorer or balance checker.

## Known failure modes

- Wallet address not found or never made a $999.99 USDC transfer — returns rich=false with condolences
- Invalid or malformed wallet address in path param — likely 4xx error
- On-chain data unavailable or RPC timeout — service error
- Payment of $0.03 USDC not completed — x402 payment required error before data is returned

## How this service works

Has a given wallet ever paid $999.99 for nothing? Checks the on-chain USDC transfer history. Returns rich=true with proof tx, or rich=false with condolences.

## Output

Returns a JSON object with a 'rich' boolean flag. If true, includes the proof transaction hash, the wallet address, and the timestamp when the flex occurred. If false, includes a condolences note. Always includes the queried wallet address.
