8 crypto and currency tools starting at 1 credit per call — real-time prices, candlesticks, market rankings, social sentiment, and news. Fittingly, your agent can pay for them in USDC via x402.
Credits are charged per call; x402 is the per-call USDC price for keyless agent payments. Advertised price = charged price, always.
