# API Request Signing ⎊ Area ⎊ Resource 1 --- ## What is the Authentication of API Request Signing? API Request Signing establishes cryptographic verification of requests directed to exchange infrastructure, mitigating the risk of unauthorized access and malicious manipulation of trading parameters. This process typically involves generating a digital signature using a private key associated with the API user, confirming the request’s origin and integrity. Securely validating these signatures is paramount for maintaining market stability and protecting user funds, particularly within high-frequency trading systems and automated strategies. Consequently, robust implementation of API Request Signing is a fundamental component of exchange security protocols and regulatory compliance. ## What is the Calculation of API Request Signing? The process of generating a signature for an API request involves hashing the request parameters alongside a secret key, creating a unique identifier representing the request’s content and originator. This hash is then digitally signed using the private key, producing a signature that can be verified by the exchange using the corresponding public key. Variations in hashing algorithms and signature schemes exist, impacting both security strength and computational overhead, requiring careful consideration based on the specific application and risk profile. Efficient signature generation and verification are critical for minimizing latency in trading systems. ## What is the Consequence of API Request Signing? Failure to properly implement or validate API Request Signing can lead to severe consequences, including unauthorized trades, account compromise, and potential market manipulation. Exchanges bear significant responsibility for ensuring the integrity of their API interfaces, and regulatory scrutiny in this area is increasing. A compromised API key necessitates immediate revocation and re-keying to prevent further unauthorized activity, demanding robust key management practices and incident response protocols. --- ## [Request for Quote](https://term.greeks.live/term/request-for-quote/) Meaning ⎊ Request for Quote systems enable institutional-grade price discovery for large-volume or complex derivatives trades by aggregating competitive quotes from market makers to minimize slippage. ⎊ Term ##
