# Overcast service reference > Per-service reference for Overcast, a local emulator for AWS APIs: what each emulated service implements, where it stops, and how to drive it. Every link below ends in `.md` and returns that page as markdown. The same page renders as HTML at the path without the extension. A service's own page comes first, followed by its sub-pages. Coverage is per operation, not per service — the support matrix at https://overcast.sh/support/ has the implementation status of each one. ## Service Reference - [ACM — AWS Certificate Manager](https://overcast.sh/docs/services/acm/index.md): Quick start, the certificate and tag operations that work, and what a request skips: no validation round trip… - [ACM — AWS Certificate Manager — ACM operations](https://overcast.sh/docs/services/acm/operations/index.md): Every ACM operation Overcast declares — 11 of 11 implemented — with status… - [API Gateway — Amazon API Gateway](https://overcast.sh/docs/services/apigateway/index.md): Quick start, invoke URLs for REST v1 and HTTP v2, the integrations and authorizers that execute… - [API Gateway — Amazon API Gateway — API Gateway operations](https://overcast.sh/docs/services/apigateway/operations/index.md): Every API Gateway operation Overcast declares — 104 of 106 implemented — with status… - [AppConfig — AWS AppConfig](https://overcast.sh/docs/services/appconfig/index.md): Quick start, the application/environment/profile/hosted-version hierarchy… - [AppConfig — AWS AppConfig — AppConfig operations](https://overcast.sh/docs/services/appconfig/operations/index.md): Every AppConfig operation Overcast declares — 20 of 20 implemented — with status… - [AppConfigData — AWS AppConfig Data Plane](https://overcast.sh/docs/services/appconfigdata/index.md): Quick start, the two AWS bindings, single-use token rotation and the poll interval… - [AppConfigData — AWS AppConfig Data Plane — AppConfigData operations](https://overcast.sh/docs/services/appconfigdata/operations/index.md): Every AppConfigData operation Overcast declares — 2 of 2 implemented — with status… - [AppRegistry — Service Catalog AppRegistry](https://overcast.sh/docs/services/appregistry/index.md): Quick start, the resource and CloudFormation coverage, how CDK awsApplication tags become associations… - [AppRegistry — Service Catalog AppRegistry — AppRegistry operations](https://overcast.sh/docs/services/appregistry/operations/index.md): Every AppRegistry operation Overcast declares — 22 of 22 implemented — with status… - [AppSync — AWS AppSync](https://overcast.sh/docs/services/appsync/index.md): Quick start, the GraphQL and realtime endpoint URLs, the data sources and authorization modes that execute for… - [AppSync — AWS AppSync — AppSync limitations](https://overcast.sh/docs/services/appsync/limitations/index.md): Where Overcast's AppSync diverges from AWS: which authorization modes are verified… - [AppSync — AWS AppSync — AppSync operations](https://overcast.sh/docs/services/appsync/operations/index.md): Every AppSync operation Overcast declares — 82 of 82 implemented — with status… - [Athena — Amazon Athena](https://overcast.sh/docs/services/athena/index.md): Athena's control plane — workgroups, query executions and tags.
