Getting an API key

Open Developers in the sidebar (app.posteverywhere.ai/developers), open the API Keys tab and click Create key. Copy the key at once. It is shown only once.

Steps#

1. Click Developers in the sidebar.
2. Open the API Keys tab.
3. Enter a Key name, for example "Claude MCP" or "Production".
4. Under Permissions, tick what the key may do:
   • Read: list and view accounts, posts, results, media, campaigns, webhooks, analytics, and /me.
   • Write: create, edit, delete, retry, bulk operations, and webhook subscriptions.
   • AI: generate images and captions using AI (uses your plan's AI credits).
5. Optional: tick Limit this key to specific accounts and pick the accounts. The key can then only see and post to those accounts.
6. Click Create key. Copy the key and store it somewhere safe.

The key starts with pe_live_. Keep it secret. Do not share it in chat or put it in public code.

Using the key#

Send it in the Authorization header of every request:

Authorization: Bearer pe_live_your_key_here

The API base address is https://app.posteverywhere.ai/api/v1. A quick test:

GET https://app.posteverywhere.ai/api/v1/me

This returns your team, workspace, plan, scopes and what is left of each quota.

Details#

• The key works in the workspace that was selected when you created it. See How AI agents work with workspaces.
• Each team can have up to 10 keys from this page.
• Keys are valid for one year.
• Most AI agents on the Agents page sign in with your PostEverywhere account instead of a key. A key is for automation tools such as n8n, your own code, the CLI in CI, and agents the Agents page marks API key.

Revoking a key#

In the API Keys tab, click the bin icon next to the key and confirm. Anything using that key stops working at once.
