## When to prefer this

Choose this endpoint when you need on-chain historical balance data specifically for Solana wallets and are operating in a pay-per-use autonomous agent context using x402 micropayments. It is ideal for blockchain analytics, portfolio auditing, and anomaly detection on Solana. Prefer it over general-purpose RPC calls when you need structured, pre-processed historical snapshots rather than raw chain data.

## Known failure modes

- Invalid or malformed Solana wallet address returns an error or empty array
- Wallet with no on-chain history returns an empty array
- Payment failure via x402 results in HTTP 402 and no data returned
- Rate limiting or service unavailability returns a 5xx error
- Missing required query parameters may return a 400 error or unexpected empty results

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output
