# Publishing headroom left > Markdown version of https://docs.postlake.dev/api/get-social-accounts-by-id-allowance . The canonical page for humans. > PostLake is the social media API for AI agents: https://postlake.dev/llms.txt `GET /v1/social-accounts/{id}/allowance` How many posts this channel has left in the network's own rolling window, read from the network rather than counted locally. Check it before planning a batch: the alternative is discovering the ceiling by being refused partway through one, with some posts already live and some not. ## Request Authenticate with a bearer API key. Agents calling over MCP authorise with OAuth instead and never handle the key. ```bash curl -X GET https://api.postlake.dev/v1/social-accounts/{id}/allowance \ -H "Authorization: Bearer $POSTLAKE_API_KEY" ``` ### Parameters | Field | Type | Required | What it is | | --- | --- | --- | --- | | `id` | string | Yes | In the URL. | ## Response Allowance (`200`). | Field | Type | Required | What it is | | --- | --- | --- | --- | | `used` | integer | Yes | | | `limit` | integer | Yes | | | `remaining` | integer | Yes | | | `windowHours` | integer | Yes | The window the count covers, so "5 left" means something. | | `platform` | object | Yes | | ### Example ```json { "used": 0, "limit": 0, "remaining": 0, "windowHours": 0, "platform": "…" } ``` ## Calling this from an agent Agents do not call REST. They call tools. Over the hosted MCP server this operation is `list_social_accounts`, and the agent authorises with OAuth so your API key is never pasted into a chat or seen by the model. You control what any one agent may do: which brands it may act for, which networks it may reach, how much a day, and whether it may spend credits bought up front. ## Errors Every failure uses one shape: a stable `type`, a granular `code`, the field at fault in `param`, and a plain-language `fix`. See https://docs.postlake.dev/errors.md . Retries are safe: send the same `Idempotency-Key` and a call that already succeeded returns its original result rather than repeating it. ## Common questions **Can an AI agent do this without the REST API?** Yes. Over MCP the same job is the list_social_accounts tool. The agent authorises with OAuth, so no API key is pasted into a chat or seen by the model, and the answer comes back in the same normalised shape. **How often can I call this?** Reads are rate limited per account and every response carries X-RateLimit-Remaining and X-RateLimit-Reset. On a 429 the Retry-After header tells you how long to wait. **What happens when it fails?** You get one error shape: a stable type, a granular code you can branch on, the offending field in param, and a fix written so an agent can correct itself rather than stop.
