Hash

A hash function is any function that can be used to map data of arbitrary size onto data of a fixed size. In the context of OriginStamp, the term hash specifically refers to the SHA-256 hash of digital content, represented as a hexadecimal string (HEX).

Proof

A proof contains all necessary data to independently verify a timestamp on the blockchain (essentially all blockchain-related information and a path in a Merkle Tree).

API Key

The API Key is used to authenticate requests to the OriginStamp API.
It must be included in each request as an HTTP header:

x-api-key: YOUR_API_KEY

Webhook

A webhook is an automated notification sent when a tamper-proof timestamp has been successfully verified.
Webhooks allow your system to react to events in real-time without polling the API.
