## 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-574f71be
```

Example prompt: What's the on-chain credit score for the wallet 0x1234abcd...5678? I want to see their 0–1000 score based on Base activity and Taskmarket history before I consider lending to them.

## When to prefer this

Choose this endpoint when you need a quick, data-only numeric credit score for an Ethereum/Base wallet address, specifically derived from Taskmarket history and Base on-chain activity. Prefer it over generic blockchain explorers when you want a single aggregated reputation score rather than raw transaction data. Ideal for DeFi lending, DAO gating, or freelancer screening workflows that need a machine-readable creditworthiness signal.

## Known failure modes

- Invalid or malformed 0x address returns an error response
- Address with no on-chain history may return a score of 0 or a sparse-data warning
- Rate limiting or payment failure (402) if the $0.003 USDC x402 payment is not processed
- Network timeouts if Base RPC or Taskmarket data sources are temporarily 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 for the queried wallet address, computed from the address's Taskmarket transaction history and activity on the Base blockchain. Higher scores indicate stronger on-chain reputation and creditworthiness.
