What it does

Honeypot check for a Base token: can you sell it after you buy? Simulates a buy and a sell on its Uniswap v2, v3 or v4 or Aerodrome pool and returns sellable, high_tax, honeypot or unknown, both taxes and the pool, plus the owner powers in its code, proxies included (mint, blacklist, pause, fee changes, upgrade), and whether one key holds them. A simulation at one block, not an audit; unknown, never a guess, and no charge if our node fails. Free: GET /v1/token. Trial: /v1/trial.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/27663.json for the price and payment options.
Pay. Call GET https://trust-agent.io/v1/token/honeypot. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
