Axelar Amplifier GMP API
The Amplifier GMP API is the HTTP REST integration layer exposed by the Axelar Amplifier relayer service. External chain integrators and relayer operators use it to publish on-chain events (CALL, MESSAGE_EXECUTED, SIGNERS_ROTATED, ITS transfer events, etc.) and to poll pending transaction tasks (EXECUTE, APPROVE_MESSAGES, ROTATE_SIGNERS) that must be submitted to destination chains. Also supports CosmWasm contract broadcast and query, and large payload pre-storage.
