Technical details
Endpoint
POSThttps://api.relai.fi/relay/1769629274857/x402/bitquery/wallet-holdingsWhen to prefer
Use this endpoint when you need on-chain token holding data for a specific wallet across popular EVM chains, especially when you want multi-chain portfolio composition rather than just native balances. Prefer this over generic block explorers when you need structured, machine-readable token portfolio data for agent workflows.
Side effects
- Missing walletAddress parameter returns validation error
- Invalid wallet address format returns error
- Unsupported chain value returns enum validation error
- Payment failure (insufficient USDC balance) blocks request under x402 protocol
- Wallet with no token holdings returns empty portfolio
- Bitquery upstream timeout or rate limit causes 5xx error
