# How to choose an API provider

> A practical checklist for choosing an API provider based on reliability, documentation, pricing, support, and production fit.

# 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

1. What happens when the API returns a temporary error?
2. Are failed requests charged?
3. Can you set spending limits or usage alerts?
4. Can you create separate keys for development and production?
5. Is there a clear path to contact support?

## Use Rock API during evaluation

Rock API helps you centralize API keys, review usage, and track billing from one dashboard. Start with the [Quickstart](/quickstart), then review [Authentication](/authentication) and [Pricing and billing](/pricing-and-billing) before production use.
