> Sleuth AI Dev Sell Check is a paid API for AI agents from x402.sleuthagent.ai, paid per call via x402, $0.099/call, status unknown (last checked 2026-09-15).

## 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-dev-sell-check-e9f8bb2c -d '<json body>'
```

Example prompt: Can you check if the dev wallet for this token dumped their holdings after launch? The contract address is 0xABC123... on Base — I want to know if the deployer sold and how much.

## When to prefer this

Use this endpoint when you need to quickly determine whether a token's deployer or dev wallet has sold holdings after launch — a key indicator of rug pulls or insider exits. Prefer this over generic blockchain explorers when you want a plain-language, AI-interpreted answer rather than raw transaction data. Ideal for pre-investment due diligence on new or unfamiliar tokens on Base.

## Known failure modes

- Invalid or unrecognized contract/wallet address returns an error or empty investigation
- Insufficient USDC balance or failed x402 payment prevents the call from completing
- Contract address not found on Base network results in a no-data response
- Rate limiting or network congestion may delay or fail the response
- Token too new or with no on-chain activity may yield inconclusive results

## How this service works

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

## Output

Returns a natural-language summary describing whether and how much the deployer wallet sold after launch (e.g. '80% of holdings sold 3 days after launch'), along with a unique request_id for tracking the query.
