Call credits.balance
Read how many credits this account has left. Say the figure back exactly as given — never work one out or recall one. Topping up is done by a person on Settings → Billing; you cannot do it here.
Authorizations
An API key minted at Settings › API & MCP. Send it as Authorization: Bearer <key>. A key carries its holder's own permissions, resolved on every call — revoking a membership closes the key's reach immediately. Keep it in an environment variable (GOOSY_API_KEY), never in a committed file.
Body
The body is of type object.
Response
The call was admitted and dispatched. ok says whether the tool succeeded — a refusal the tool itself produced is still a 200, exactly as it is a successful JSON-RPC result over MCP.
