Endpoint
POSThttps://api.relai.fi/relay/1782567677091/api/x402/wallet-activity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, affordable ($0.01) lookup of recent on-chain activity for a specific Base (eip155:8453) wallet address and want structured transaction data (hash, time, from/to, value, success) powered by Covalent. Ideal for agents monitoring wallet behavior, auditing addresses, or surfacing transaction history without building a direct Covalent integration.
Side effects
- 402 Payment Required returned first — agent must pay $0.01 USDC on Base to 0x973a31858f4d2125f48c880542da11a2796f12d6 and retry
- Invalid or malformed Base address returns an error
- Address with no transaction history returns empty result set
- Covalent data lag may mean very recent transactions are not yet indexed
- Network congestion on Base may delay data freshness
