# ChainK9 Deployer Report API

> ChainK9 Deployer Report API is a paid API for AI agents from api.chaink9.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-28).

Looks up the verified deployer address and known deployment history for a token contract on BNB Smart Chain, Ethereum, or Base.

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 chaink9-deployer-report-api-be55d39c
```

Example prompt: Can you look up the deployer and creation history for token 0x0E09FaBB73Bd3Ade0a17ECC321fD13a19e81cE82 on BNB Smart Chain — the creation transaction is 0xabc123...def456?

## When to prefer this

Use this endpoint when you need to identify the deployer wallet of a specific token and look up their deployment history — particularly for pre-trade due diligence on BNB Smart Chain, Ethereum, or Base tokens. It complements honeypot/risk-check endpoints by providing on-chain provenance context. Prefer this when you already have both the token address and the original contract creation transaction hash, and need structured deployer attribution rather than a full risk score.

## Known failure modes

- Token address not found in previously submitted verified creations — returns empty known_deployments and null latest_scan
- Invalid token address format (not a 0x + 40 hex char address) — validation error
- Invalid creation_tx format (not a 0x + 64 hex char hash) — validation error
- Unsupported chain value — enum validation error
- Token/creation_tx mismatch — may return no verified_creation data
- Payment failure via x402 — request not processed

## How this service works

Token risk checks for BNB Smart Chain, Ethereum and Base, for AI agents and trading bots. ChainK9 forks the chain and really buys and sells a token in a sandbox before you do, so a honeypot is caught by what it does, not by what its code looks like.

## Output

Returns a JSON object containing the verified creation details (token address, deployer wallet, creation block number, creation transaction hash), a list of known prior deployments by the same deployer with any available scan data, a coverage note indicating data scope, and a truncated flag if results are partial.
