Axway API Gateway vs Google Cloud Endpoints

Axway API Gateway has no write-up on Specifiction yet; its figures are above.

Google Cloud Endpoints manages APIs with tools for securing access, monitoring activity, analyzing usage, and setting quotas. It supports API descriptions written in OpenAPI 2.0 or 3.x, as well as gRPC, and provides management through ESP or ESPv2. Documented deployment backends include Google Kubernetes Engine, Compute Engine, Kubernetes, App Engine, Cloud Run, Cloud Run functions, and Knative serving; proxy availability varies by backend. Endpoints is optimized for Docker and can host an API wherever Docker runs, provided it has internet access to Google Cloud. API keys can be required and validated to identify a Google Cloud project for quotas, billing, and monitoring. Documented user authentication options include Firebase Authentication and Auth0, using JWT validation by ESP. Logs and metrics are viewable in the Google Cloud console. Pricing depends on API calls and Service Control calls: the Free usage tier is free for 1,999,999 calls; Standard is $3 a month for 2,000,000 to 1,000,000,000; and High-volume is $1.50 a month for 1,000,000,000 and above. Listed rates are per million API calls.
