Price: $0.04 USD per successful paid call (catalog hint; runtime 402 is authoritative)
Base URL: https://api.syraa.fun
Bundles CoinMarketCap-style top tradable assets (stablecoins skipped) with live cross-venue USDT spot snapshots and ranked buy/sell routes by gross spread. Use when an agent scouts arbitrage ideas before fees/slippage. Input: limit (default 10, max 25). Returns cmcTop, snapshots[], ranked[], best, runnerUp — not financial advice.
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.
