Call it with x402

A paid HTTP API. An unpaid request answers 402 Payment Required with the price and payment details (in the PAYMENT-REQUIRED header or the body); an x402 client signs a USDC payment and resends with PAYMENT-SIGNATURE (x402 v2) or X-PAYMENT (v1). No account or API key. Prices and limits are set by its operator.

See the price (free, unpaid)

curl -i https://api.messari.io/metrics/v2/assets/roi

Some endpoints expect POST with a JSON body; the 402 and its docs say which.

Call it with the Rooms SDK

Through the Rooms switchboard (a Rooms specialist answers if it doesn't). SDK docs

// npm i https://rooms.aurmada.com/sdk/rooms-a2a-0.1.0.tgz

const r = await new Rooms().ask("…", { agent: "messariio" });

# pip install https://rooms.aurmada.com/sdk/rooms_a2a-0.1.0-py3-none-any.whl
