**An agent can connect on its own if it already holds `api_key`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

### Tool changes

- 2026-11-13 `split_into_layers` changed (description, inputSchema)
  - before: Split a flat image (PNG, JPG or WebP) into named transparent layers, with the hidden parts behind objects filled in. Costs 1 credit per layer returned (at most 17); the account needs at least 5 credits to start. Pass the image as a public https URL or as base64. Waits up to 50 seconds; if it is still processing, call get_layers later.
  - after: Split a flat image (PNG, JPG or WebP) into named transparent layers, with the hidden parts behind objects filled in. Costs 1 credit per layer returned (up to 17 by default, or up to 100 when prompt lists or asks for more parts); the account needs at least 5 credits to start. Pass the image as a public https URL or as base64. Waits up to 50 seconds; if it is still processing, call get_layers later.

## Tools (4)

- `get_credits`: Credits available on this Unmerge account. One credit is one layer returned.
- `get_layers`: Status of a split. When ready, returns every layer with its name, position and a PNG download URL valid for one hour. Free.
- `split_into_layers`: Split a flat image (PNG, JPG or WebP) into named transparent layers, with the hidden parts behind objects filled in. Costs 1 credit per layer returned (up to 17 by default, or up to 100 when prompt lists or asks for more parts); the account needs at least 5 credits to start. Pass the image as a public https URL or as base64. Waits up to 50 seconds; if it is still processing, call get_layers later.
- `unlock_layers`: For a split with status needs_credits: pay the extra credits owed (shown as credits.owed) so the layer files become available. Charges once even if called again.
