AWS API Changeloghigh

• AWS publishes API changes through What's New feed and service-specific changelogs; Quake AI uses a unified api-changelog page

DigitalOcean APIhigh

• Uses REST API over HTTPS with Bearer token authentication via personal access tokens, not OpenStack's Keystone token-based auth.
• Base URL https://api.digitalocean.com/v2, incompatible with OpenStack APIs like Nova/Neutron.
• Scoped permissions tied to granular API scopes based on team roles, unlike OpenStack role/project assignments.
• Rate limits: 5000/hour, 250/minute.

Cloud APIhigh

• Proprietary REST API over HTTPS with Bearer token auth, not OpenStack Identity API (keystone) endpoints or mechanisms.
• Base URL https://api.hetzner.cloud/v1/ with resource-specific endpoints (e.g., /servers) vs OpenStack service endpoints (nova, cinder).
• No multi-project handling in single auth; separate per-project tokens vs keystone scopes/projects.
• Missing identity/catalog endpoints; no service discovery via API.
