Fifteen endpoints reach end of support on Ankr RPC on 15 September 2026. Seven networks go entirely, testnets included, and six testnets and variants go while their network stays. All fifteen already require a Premium key, so nothing changes for a keyless or Freemium integration. No method limits, error codes or rate limits changed on any network that stays.
From 15 September Kaia runs on full nodes, and how far back a call can reach changes. Tracing keeps working for recent history, roughly a day of blocks, and a state read at an explicit older block needs archive state that a full node does not hold. Everything else on Kaia stays as it is: the same endpoints on mainnet and testnet over HTTPS and WSS, the same rate limits, the same error codes, and the same method list apart from the five listed below.
Sixteen networks stopped answering keyless and Freemium calls on 31 August, 29 endpoints across mainnets and testnets. They need a Premium key from now on. Sui JSON-RPC moved off the keyless endpoint and stays free on Freemium. Swell reached end of support. No method limits, error codes or rate limits changed anywhere else.
Allora, Botanix, Corn, Horizen EON, Moonbeam and Tenet reach end of support on Ankr RPC and are gone from the chain list and the docs. Mantle Sepolia testnet is delisted too, while Mantle mainnet is unaffected. No method limits, error codes or rate limits changed anywhere else.
Two deprecations need your attention: Sui is retiring JSON-RPC network-wide, with the hard cutoff in mid-October, and Bahamut is no longer served. Alongside that, we rebuilt the Advanced API reference, split the per-chain RPC pages, and rolled node clients forward on roughly 25 chains. Eight of those tracked a network upgrade with a hard activation, where a node left on the old version stops following the chain.
