# Read uploaded-media retention policy > Markdown version of https://docs.postlake.dev/api/get-media-policy . The canonical page for humans. > PostLake is the social media API for AI agents: https://postlake.dev/llms.txt `GET /v1/media/policy` Applies to PostLake uploads on every plan while the account remains open, not external URLs. Minimum dates are not expiry dates. Source URLs are public; cancelling a post does not delete media. This is publishing storage, not a backup service. See https://postlake.dev/terms#media-retention. ## 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/media/policy \ -H "Authorization: Bearer $POSTLAKE_API_KEY" ``` ## Response Versioned minimum retention, scheduled protection and exceptions (`200`). | Field | Type | Required | What it is | | --- | --- | --- | --- | | `version` | string | Yes | | | `minimumDays` | integer | Yes | | | `scheduledProtection` | string | Yes | | | `automaticExpiry` | boolean | Yes | | | `exceptions` | array of string | Yes | | | `scope` | string | No | | | `accountRequirement` | string | No | | | `publicUrls` | boolean | No | | | `postRemovalDeletesMedia` | boolean | No | | | `backupService` | boolean | No | | ### Example ```json { "version": "…", "minimumDays": 0, "scheduledProtection": "…", "automaticExpiry": false, "exceptions": [ "…" ], "scope": "…", "accountRequirement": "…", "publicUrls": false } ``` ## Calling this from an agent Agents do not call REST. They call tools. Over the hosted MCP server this operation is `upload_media`, 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 . Check the result before retrying a write. Only operations that explicitly support idempotency can safely replay an `Idempotency-Key`. ## Common questions **Can an AI agent do this without the REST API?** Yes. Over MCP the same job is the upload_media 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.
