## 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 on-chain-credit-score-for-0x-address-4d842927
```

Example prompt: What's the on-chain credit score for wallet 0x1234abcd...? I want to know how trustworthy this address is based on its Base activity and Taskmarket history.

## When to prefer this

Choose this endpoint when you need a quick, quantified reputation signal for a specific Ethereum/Base wallet address, particularly in contexts involving Taskmarket activity. It is ideal for DeFi lending screens, access control gates, or counterparty vetting where on-chain behavioral history is more relevant than traditional credit checks.

## Known failure modes

- Missing or malformed address parameter returns an error
- Address with no on-chain history may return a very low or zero score
- Non-Base/non-Taskmarket addresses may lack sufficient data for accurate scoring
- Payment failure (x402) if USDC balance is insufficient
- Network timeout if Base RPC or Taskmarket data source is unavailable

## How this service works

Data-only 0-1000 credit score for a 0x address from Taskmarket history and Base activity. ?address=0x...

## Output

A numeric credit score between 0 and 1000 reflecting the on-chain creditworthiness and activity history of the queried wallet address, aggregated from Taskmarket participation history and Base blockchain activity signals.
