Every caller gets 25 free calls; then pay per call in USDC via x402 (Base, Polygon, Arbitrum, Solana) or by card with prepaid credits from /credits. No account needed; failed calls are never charged; per-tool reliability is public at /status. Crypto: token prices and wallet portfolios from Uniswap v3, chain reads on Base, Ethereum, Arbitrum, Optimism and Polygon, OFAC sanctions screening.
