# Sleuth AI Funding Chain Trace

> Sleuth AI Funding Chain Trace is a paid API for AI agents from x402.sleuthagent.ai, paid per call via x402, $0.099/call, status unknown (last checked 2026-09-13).

Traces the on-chain funding history of a wallet address across multiple blockchains, identifying hops, sources, and funding patterns.

## 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 sleuth-ai-funding-chain-trace-4c7159a4 -d '<json body>'
```

Example prompt: Can you trace the funding chain for the wallet 0xAbCd1234... on Ethereum and tell me where its funds originally came from — how many hops back and what the original source is?

## When to prefer this

Choose this endpoint when you need deep on-chain funding provenance for a wallet — specifically tracing backward through multiple hops to identify original funding sources. It is purpose-built for blockchain forensic investigation across Base, Ethereum, Arbitrum, Polygon, BSC, Solana, and Robinhood Chain. Prefer it over generic blockchain explorers when you need AI-synthesized narrative summaries alongside structured hop data, or when investigating suspicious wallets for compliance, fraud, or due diligence purposes.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported chain value not in the enum causes a validation error
- Wallet with no on-chain history may return an empty node set
- Deeply nested or heavily mixed funding paths may be truncated (truncated=true in nodes)
- Payment failure via x402/USDC results in 402 response before investigation runs
- Network timeout on complex multi-hop traces across chains

## How this service works

Pay-per-call on-chain investigation API (x402, USDC on Base).

## Output

Returns a structured investigation result including: a natural-language narrative summarizing the funding trace (e.g. 'funds trace back through 4 hops to a Coinbase withdrawal'), a set of data nodes containing tabular rows of hops with addresses and amounts, row counts, column headers, and a summary per node, plus a request_id and optional conversation_id for follow-up queries.
