## When to prefer this

Use this endpoint when you need to retrieve the historical on-chain transaction record for a specific wallet address on Base, Arbitrum, or Solana and are comfortable with x402 micropayment-based billing at $0.01 USDC per call. Prefer this over general blockchain explorers when building automated agent workflows that need programmatic, structured access to transaction history data.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Malformed or invalid wallet address returns an error
- Address with no transaction history returns an empty result
- Payment failure via x402 micropayment results in 402 response
- Rate limiting or server unavailability returns 5xx error
- Backup domain may have higher latency or occasional downtime
