Callable agent services search across protocols

Price and access

• $0.002 per call. Bad input is refused before any charge.
• No account needed: the unpaid call answers HTTP 402 with the exact price, your x402 or MPP client pays, the paid call returns the data with a receipt.
• Cannot sign payments? A prepaid access key works on this route and on MCP. Other ways to pay: /pay.
