Pyth Network API overhaul risks freezing 300 DeFi protocols

Pyth Network missed its 16:00 UTC cutover deadline on Aug. 26, introducing a new requirement for developers using its Hermes price-delivery service: an API key is now necessary for requests. Users of protocols already integrated with the oracle do not need to take direct action. The existing hermes.pyth.network address will redirect to the upgraded backend, requiring authentication post-deadline. Developers can also use https://pyth.dourolabs.app/hermes, passing the key as a bearer token or SDK access token. The routes and response shapes remain unchanged. The cutover mandates that direct Hermes callers and Sui integrators update their authentication or configuration, while end users of protocols are unaffected. The upgraded Hermes endpoint is designed for the new Pyth Core contract, and the migration guide warns that incorrect endpoint or contract settings can prevent applications from verifying price updates. Applications lacking the required key may fail to complete authenticated requests, while mismatched settings can lead to unverified data. Sui integrations require developers to update both the client fetching price data and the on-chain Move package dependency. A live DefiLlama oracle table indicates Pyth is linked to 316 protocols with approximately 2700000000 dollars in total value secured. As of the deadline check, there were no confirmed outages or loss of funds.
