Price: $0.08 USD per successful paid call (catalog hint; runtime 402 is authoritative)
Base URL: https://api.syraa.fun
Answers one natural-language crypto question by selecting and running Syra tools (news, signals, on-chain reads) server-side. Use when an agent needs a grounded synthesis instead of calling many APIs manually. Input: question (required). Returns success, markdown/plain response, and toolUsages[] showing which tools ran. Treasury-paid tool calls included; not trade execution.
This is a pay-per-call route: unpaid requests return HTTP 402 until you settle USDC and retry with PAYMENT-SIGNATURE or X-PAYMENT. See x402 wire format.
