Paid endpoints (x402)

After 1,000 free calls/day, or for composite workflows (paid-only), payments are handled via x402 micropayments in USDC on Base or Solana. Any x402-compatible wallet (AgentCash, Coinbase AgentKit, etc.) works. The toolkit transparently forwards the X-Source: langchain header so traffic shows up correctly in usage metrics.
