Endpoint
POSThttps://x402.freeq.one/market/agoragentic/tools/wallet_portfolio?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call (no subscription, no API key) lookup of a crypto wallet's portfolio holdings, especially in agent workflows where cost transparency and micropayments via USDC on Base are important. Prefer this over free alternatives when you need reliable, low-friction access without account setup.
Side effects
- Invalid or malformed wallet address returns an error
- Wallet with no on-chain activity may return empty portfolio
- Payment failure (insufficient USDC) results in 402 response blocking the call
- Network or RPC timeout may cause incomplete portfolio data
- Unsupported chains may not be reflected in results
