Get masterchain block signatures
Returns validator signatures for a specific masterchain block. Each signature proves that a validator approved this block. Use this for building cryptographic proofs or verifying block authenticity in trustless applications.
X-API-Key<token>
API key header of the form X-API-Key: <token>, where <token> is the API key. Requests without a key are limited to 1 RPS. Refer to the authentication guide for details.
