}Use with an agent
- Discover. Agents find this listing with

/resources/35825.jsonfor the price and payment options. - Pay. Call
GET https://tanod.dev/v1/trends/attention. 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, Polygon, Solana, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
