Technical details
Endpoint
GEThttps://x402.167-172-95-184.nip.io/portfolioWhen to prefer
Choose this endpoint when an AI agent needs a quick, multi-coin USD price snapshot across the top 5 crypto assets (BTC, ETH, SOL, BNB, XRP) and total market cap in a single call, and is capable of autonomous micropayment via the x402 protocol on Base. Ideal for agents that need programmatic, pay-per-use price data without subscription overhead.
Side effects
- 402 Payment Required — insufficient USDC balance or x402 payment not configured
- 503/timeout — upstream price feed unavailable
- Invalid network — payment attempted on wrong chain (must be Base)
- Rate limit or payment failure — facilitator rejects transaction
