What it does
Use when an agent must confirm a Base transaction or payment landed: did it succeed, who paid whom, how much of which token. Input: hash. Output: JSON status (success/reverted), block+time, confirmations, from, to, ETH value, fee (L2 gas + L1 data fee), decoded ERC-20 transfers with symbol and decimal amount (first 25). Unknown or unmined hash: 404, not charged. Example: ?hash=0x284f8abed91b5631ee28bdb1ccfe78374e18c480cb2ab25f28e3bfac5210fe0b

}Use with an agent
- Discover. Agents find this listing with
GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP toolsearch_resources, or/discovery/resources. - Inspect. Fetch
/resources/34842.jsonfor the price and payment options. - Pay. Call
GET https://1gateway.dev/v1/onchain/base/tx. The provider answers402with its payment requirements. An x402 client signs one of the options below and retries withPAYMENT-SIGNATURE. - Execute. The provider returns
200with 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.
