What it does

Teardrop get_wallet_portfolio: Get aggregated token holdings with USD values for a wallet address. Tracks 19 major assets on Ethereum and 12 on Base, including spot, lending, liquid-staking, restaking, and stablecoin assets. Sorted by USD value. Returns up to 20 holdings. Includes native ETH balance in the holdings list - calling get_eth_balance separately after this is redundant.

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/37918.json for the price and payment options.
Pay. Call GET https://api.teardrop.dev/tools/mcp#get_wallet_portfolio. 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.
