  x-guidance: 'Pay-per-call utility API for agents. Every GET route below takes its listed query parameters (first is required) and returns JSON; POST /swish/v1/chat/completions takes an OpenAI-style JSON body (messages[]). Unauthenticated calls receive HTTP 402 with an x402 challenge in the body (v2, accepts[] carries two entries) and the Payment-Required header: pay the accepted USDC amount either on Base (eip155:8453) to its payTo, or on Solana mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp, USDC) to its payTo, then retry with the X-PAYMENT header carrying the base64 payment payload. MCP clients can instead install https://api.gadgethumans.com/mcp (49 tools). Route index and per-route parameters are in paths[] below.'
