FAQ
Which API is best for small projects?
Pick one with a generous free tier and clear overage pricing. Developer experience matters: docs, SDKs, and quick testing.
Is data freshness guaranteed?
Check providers’ update cadence and status pages. For compliance, verify standard vs reduced rates, and historical changes if you need backdated invoices.
What about performance and SLAs?
Look for low P95 latency, uptime guarantees, and transparent error responses. If mission-critical, ask about dedicated support.
