# SpendTheBits DeFi Contract Reputation Lookup

> SpendTheBits DeFi Contract Reputation Lookup is a paid API for AI agents from x402.spendthebits.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-12).

Returns an 8-field reputation summary for a DeFi smart contract, covering exit amount, yield split, audit links, incident notes, admin, age, holder concentration, and governance — without producing a numeric score.

## 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 spendthebits-defi-contract-reputation-lookup-767835c1
```

Example prompt: Before I put money into this yield protocol, can you pull up the reputation summary for contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum (chain ID 1) — specifically the audit links, any incident notes, and who the admin is?

## When to prefer this

Choose this endpoint when you need raw, structured due-diligence fields on a specific DeFi contract without a single risk score — particularly when you want audit links, governance details, and incident notes surfaced separately. Prefer it over the sibling 0-100 safety score endpoint when you want transparency into individual signal components rather than an aggregated verdict, or when the contract is obscure and may not score reliably.

## Known failure modes

- Missing required chain_id or address returns a validation error
- Unrecognized or unsupported contract address returns unknown for all fields rather than an error
- Invalid EVM chain ID may result in no data found
- Network issues or x402 payment failure prevent the call from completing
- Contract with no on-chain history may return mostly unknown fields

## How this service works

Eight lines on one contract before money moves: exit amount, yield split, audit links, incident note, admin, age, holder concentration, and governance. Unknown stays unknown. No score.

## Output

A structured JSON object with eight reputation fields: exit amount, yield split, audit links, incident note, admin address/details, contract age, holder concentration, and governance info. Unknown fields are returned as unknown rather than omitted or scored; no aggregate numeric score is produced.
