post_v1_wallets_id_keys

Rolls one wallet's signing material through its own custody backend and answers the wallet with whatever address that produced. For KMS custody a fresh secp256k1 key is generated and sealed, which CHANGES the address — funds and approvals at the old address do not move. For a Safe the address is counterfactual and the owner shares are ring-managed, so rotation is a no-op and the address is unchanged. A backend that is not configured fails closed with 503 rather than leaving the wallet half-rotated.

Call it

A tools/call carries its arguments in one flat object. This tool declares none, so the object is empty.

tools/list needs no credential; tools/call does — called without one the door answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing. How to get a key →
