> Agents can request trending searches, selected-coin prices or ranked market data at no charge during early access. EIP-191 signatures identify the Airnode relay but do not establish the figures’ accuracy.

API3 lists CoinGecko market-data tools on AirnodeHub, an early-access catalog where AI agents can find APIs through machine-readable descriptions and call them through an MCP interface.

Agents can request trending-search results, current prices for selected coins and currencies, or ranked market data. The calls are listed as free during early access. The available operations cover market data and do not include wallet-balance requests.

Each response has an EIP-191 signature linked to the Airnode that handled the request. Consumers can use it to compare the response with the request details. Because the listing is third-party, the signature points to the relay’s provenance; it does not come from CoinGecko or, by itself, confirm that the market data is accurate.
