Look up supported blockchain network metadata and chain IDs for $0.001 USDC

What it does

Look up supported blockchain network metadata and chain IDs for $0.001 USDC. Static first-party registry only—no live RPC, balances, blocks, receipts, gas, or contract reads. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

Use with an agent

1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
2. Inspect. Fetch /resources/31164.json for the price and payment options.
3. Pay. Call GET https://api.delx.ai/api/v1/x402/chain-network-info. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
4. 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, Solana, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
