An idempotency key is a globally unique key generated by the client for each operation (usually a UUID) and sent to the external service with the request; the server checks whether the key already exists before processing, and if it does, returns the previous result without executing the actual action again.

VerifiedA common technique for achieving idempotency is for the client to generate a unique idempotency key sent with the request, while the server records the result associated with that key and returns the cached result upon receiving a duplicate request.78% similarUnverifiedWhen using Idempotency-Key, the client is responsible for generating the key (typically using UUID v4), while the server is responsible for checking and storing it.73% similarUnverifiedSome platforms detect the source of simulated keyboard input, and a simple send_keys may be identified as abnormal behavior.66% similarUnverifiedThe non-determinism in tool call ordering causes cache keys based on request body hashes to identify functionally identical requests as different requests, resulting in cache misses.66% similarUnverifiedCommon approaches to achieving idempotency include assigning a unique request ID (Idempotency Key) to each operation, which the server uses for deduplication.65% similar
