## 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 pyfile-toolkit-counterparty-reputation-lookup-02052f2d
```

Example prompt: Check the Taskmarket reputation for the address 0x1234abcd... — I want to know their completion rate, how many tasks they've posted, any awards, and whether there are any risk flags before I work with them.

## When to prefer this

Use this endpoint when you need to assess the trustworthiness of an Ethereum address specifically within the Taskmarket ecosystem — it provides Taskmarket-native reputation signals (completion rate, awards, risk flags) rather than generic on-chain activity. Prefer this over generic blockchain explorers when the task context is a Taskmarket engagement.

## Known failure modes

- Invalid or malformed 0x address returns an error or empty result
- Address not found on Taskmarket returns no reputation data
- Network timeout or service unavailability returns HTTP 5xx
- Payment failure (x402) if USDC payment is not properly attached

## How this service works

## Output

Returns structured reputation data for the queried 0x address on Taskmarket, including number of tasks posted, task completion rate, any awards earned, and risk flags indicating suspicious or problematic behavior.
