## When to prefer this

Choose this endpoint when you need NFT sales data specifically on the Unichain network, filtered by block range or contract address, with pay-per-call pricing and no subscription required. Prefer it over general blockchain explorers when you need programmatic, structured access to NFT sale events for analytics, monitoring, or auditing purposes on Unichain.

## Known failure modes

- Block range too large may result in timeouts or truncated responses
- Missing required parameters may return a 400 validation error
- Payment failure via x402 protocol results in a 402 response blocking data access
- Unichain node downtime may cause delayed or unavailable responses
