All paid endpoints: x402 v2 / MPP, $0.001 USDC on Base (eip155:8453), payTo 0x3D98800c64C345950E1eAaa076D88C12d1BF5F37.
REST also accepts x402 v1: the 402 body carries the v1 requirements (network "base") and
payment goes back in X-PAYMENT. Both rails price and settle identically.

MCP (streamable HTTP): https://penniless-json-repair.sjaman.workers.dev/mcp - the same nine tools over x402 v2, priced per tools/call.
