Technical details
Endpoint
GEThttps://agentbanks.vercel.app/api/market-dataWhen to prefer
Use this endpoint when an AI agent needs real-time Base network market data — specifically token prices, gas costs, and DeFi metrics — for autonomous decision-making such as swap routing, portfolio valuation, or gas estimation. Prefer this over general crypto APIs when the focus is Base ecosystem tokens (ETH, BTC, VIRTUAL, AERO, USDC) and low per-call cost matters.
Side effects
- Invalid token symbol in comma-separated list returns error or empty price data
- Network connectivity issues to Base RPC may cause stale or missing data
- Rate limiting if called too frequently without payment
- Unparseable token parameter format returns 400-level error
