Postproxy
A REST API (with SDKs and an MCP server) that publishes posts to 11 social networks such as Instagram, LinkedIn, X, TikTok and YouTube from one request, and reads and answers comments, DMs and Google Business reviews.
You skip building and maintaining a separate OAuth flow, media rules and retry logic for every social network; one payload goes out and you get a per-platform status back.

For your agent
A request your code or agent can make (add your key):
https://api.postproxy.dev/api/calendar?country=US- Send `Authorization: Bearer <key>` to https://api.postproxy.dev/api/...; for agents use the hosted MCP server https://mcp.postproxy.dev/mcp with the key in the `X-Postproxy-API-Key` header, or the npm package `postproxy-mcp` (stdio); use sandbox mode while testing.
- Do not resell raw API access or present Postproxy as your own API
- Respect per-profile hourly soft limits and the 20 posts/day cap on X
- Prefer the key in a header over the `?api_key=` query string so it does not end up in logs
