Choosing well
Check how you will access it
Platforms in this category include web, API, iOS, macOS, Android and self-hosted options. Confirm that the service fits your workflow before signing up.
Android access may mean a dedicated app, a mobile web interface or an API used by another app, so check the product details rather than assuming phone support.
Compare free and paid plans
A free plan can help you evaluate an API before paying. Review what the free tier permits and whether it has a monthly request limit.
Paid starting prices differ by service. Examples in this category include Open Exchange Rates from $12 per month, IPinfo from $26 per month on annual billing, and Intrinio from $150 per month.
Match limits to your workload
Look at both the monthly request limit and the rate limit. A plan may allow a set number of requests over a billing period while also restricting bursts or requests per time interval.
Estimate how often your app will call the API and leave room for retries, background jobs and growth.
Check coverage and history
Data coverage varies by service. Compare the places, instruments, fields or records you need, along with the availability of historical data.
For example, services in this category address exchange rates, market data, weather, address validation, IP information and corporate records.
Review integration features
API style, webhooks and official SDKs affect how quickly your software can connect and respond to changes. Check which languages or integration methods the maker documents.
If you need to receive updates instead of polling, verify that webhooks cover your intended events.
