Terms

Fair use, plainly stated.

The APIs are provided free of charge for lawful use, without a guarantee of uninterrupted availability or fitness for a particular purpose.

Acceptable use

Do not disrupt the service, evade controls, submit unlawful material, or use endpoints in ways that create risk for others.

Validate critical information independently. Reference data can change and utility outputs are not professional advice.

Endpoints, limits, and response formats may evolve. Breaking API changes will use a new major route version where practical.
