API reference · Media
Read uploaded-media retention policy
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.

}Limits
Reads are limited to 600 requests a minute per account. Every response carries X-RateLimit-Remaining and X-RateLimit-Reset, and a 429 includes Retry-After so a client can back off without guessing. Reads of network data (comments, followers, conversations) are metered in credits; reads of your own PostLake state are not.
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. The reply comes back in the same normalised shape you see above, which is what lets an agent reason about it without a per-network branch.
You control what any one agent may do with it: which brands it may act for, which networks it may reach, how much it may do in a day, and whether it may spend credits you bought up front. See the MCP server.
Errors
Every failure uses one shape: a stable type, a granular code, the field at fault in param, and a plain-language fix. An agent can act on it without a person reading the message. See Errors and retries.
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. Full list on Errors and retries.
