Effective September 2026
Growpost is used today through the web app at growpost.space, not through a public third-party API. This page documents what is available now and how to get access to more.
OpenAPI Reference
The current API surface is published as an OpenAPI 3.0 document at /openapi.yaml. Today it covers the public service-status endpoint; it will grow as partner API access rolls out.
Authentication
Growpost's first-party web and mobile clients authenticate with a bearer token issued at login. Third-party API access is not self-serve yet — if you want to integrate with Growpost, email hello@growpost.space and we'll set up API access for your use case.
Service Status
GET https://api.growpost.space/health returns 200 with {"status":"ok"} when the API is up. This endpoint is public and requires no authentication.
Machine-Readable Site Summary
Agents and crawlers can read /llms.txt for a short index of this site, or /llms-full.txt for the full content in Markdown.
Changelog
API and product changes, including deprecations, are tracked on the Changelog.
