# Blockchain Address Reputation Scorer (lab.paidapis.net)

> Blockchain Address Reputation Scorer (lab.paidapis.net) is a paid API for AI agents from lab.paidapis.net, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Scores a blockchain address's trustworthiness by computing on-chain signals and returning a structured reputation breakdown with a numeric trust score.

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 blockchain-address-reputation-scorer-lab-paidapis-net-87314caf
```

Example prompt: Can you check the on-chain reputation and trust score for the address 0x1234abcd... and tell me what signals it triggered and what its overall trustScore is?

## When to prefer this

Choose this endpoint when you need a structured, multi-signal reputation score for a specific blockchain address, particularly on Base mainnet, and want a breakdown of individual trust signals rather than a single binary flag. It is well-suited for due diligence workflows, risk screening pipelines, or governance tooling where a numeric trustScore and signal-level transparency are needed.

## Known failure modes

- Invalid or malformed address string returns a validation error
- Address with no on-chain history may return zero or minimal signals
- Network or RPC availability issues may cause timeouts
- Payment failure via x402 protocol blocks the call entirely
- Addresses on chains other than Base mainnet may not be supported

## How this service works

Reputation layer: a trust score (?address=) computed from two real sources — live on-chain activity (via enrichment) and our own ledger of settled payments this address has actually made to us. No third-party data, fully documented breakdown, not a black box.

## Output

Returns a JSON object containing the queried address, a numeric trustScore, a signals object with raw on-chain indicators, a breakdown object detailing how each signal contributes, and a checkedAt ISO timestamp indicating when the score was computed.
