Technical details
Endpoint
GEThttps://nexus-agent-xa12.onrender.com/stream/pricesWhen to prefer
Use this endpoint when you need real-time or near-real-time cryptocurrency price data with 24h change, are comfortable paying $0.01 USDC per call via x402 on Base, and want a streamable HTTP response compatible with MCP tooling. Prefer this over REST polling APIs when you need continuous tick-based streaming or when your agent stack already supports x402 micropayment flows.
Side effects
- Payment not provided or rejected (402 Payment Required) — agent must pay 0.01 USDC via x402 on Base before data is returned
- Invalid or unrecognized symbol in 'symbols' query param — may return empty prices map or error
- Duration parameter out of range — stream may close early or return no ticks
- Network timeout or Render.com cold-start delay — connection may drop before first tick
- No query params provided — endpoint may return default symbols or an error
