What is an API?
An API lets one program request information or actions from another. Many API providers ask you to create an API key, a secret code that identifies your account. Keep keys private: anyone who has your key can use your account and may run up charges.
Company names and labeled buttons open official provider pages. Get an API key opens key management on the provider’s website; it does not generate a key inside this app. Some tools need installation, a partner agreement or access approval rather than an API key. Document-sourced entries are labeled by access type; a listing does not guarantee current eligibility or pricing.
