How to choose an API provider
Choosing an API provider is an operational decision, not only a feature comparison. Before you subscribe, check whether the provider can support your use case in production.What to review first
- Documentation quality: clear authentication, request examples, error codes, and limits.
- Pricing shape: recurring fees, usage charges, overage rules, and refund policy.
- Reliability signals: status history, support response time, and rate limit behavior.
- Access control: key management, project isolation, and permission boundaries.
- Migration effort: how much application code changes if you switch later.
Questions to ask before subscribing
- What happens when the API returns a temporary error?
- Are failed requests charged?
- Can you set spending limits or usage alerts?
- Can you create separate keys for development and production?
- Is there a clear path to contact support?
