Fifteen endpoints reach end of support on 15 September
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.
Deprecations and end-of-support
Networks removed entirely, from 15 September 2026
| Network | Endpoints that stop answering |
|---|---|
| Fuel | mainnet and Sepolia testnet |
| Xai | mainnet and testnet |
| Syscoin | mainnet |
| Rollux | mainnet |
| Kusama | mainnet |
| Litecoin | mainnet |
| Tenet | the EVM endpoint, the last Tenet surface after the August end of support |
We remove their API reference pages on the same date, and inbound links resolve to the chain list instead of returning a 404. The branded domains for these networks retire with them: xai-rpc.com, syscoin.public-rpc.com, rollux.public-rpc.com, tenet-evm.public-rpc.com and fuel-rpc.com.
Testnets and variants removed, the network stays
| Network | Removed | Stays |
|---|---|---|
| IoTeX | testnet | mainnet |
| zkSync Era | Sepolia testnet | mainnet |
| Gnosis | testnet Beacon | Gnosis, Gnosis Beacon, Gnosis testnet JSON-RPC |
| 0G | Galileo testnet EVM | 0G mainnet EVM, mainnet BeaconKit, Galileo testnet BeaconKit |
| vFlow | testnet | mainnet, Volta testnet |
| Dogecoin | testnet | mainnet |
Everything in the "stays" column keeps the same URL, the same plan, the same rate limits and the same method list.
Fuel: where to move
Fuel operates public GraphQL endpoints for both networks, and they speak the same API as ours:
| Network | Fuel endpoint |
|---|---|
| Mainnet | https://mainnet.fuel.network/v1/graphql |
| Sepolia testnet | https://testnet.fuel.network/v1/graphql |
Every query and mutation on our Fuel pages works there unchanged, so the switch is the URL and nothing else. Their documentation covers the limits that apply.
Worth checking on your side
- Search your configuration for the endpoint path, not the network name. These are the fifteen strings:
fuel,fuel_sepolia,xai,xai_testnet,syscoin,rollux,kusama,litecoin,tenet_evm,iotex_testnet,zksync_era_sepolia,gnosis_testnet_beacon,0g_galileo_testnet_evm,vflow_testnet,dogecoin_testnet. They appear onrpc.ankr.comafter/premium-http/or on their own, and the older keyless form is/http/<name>. - A call to any of these without a Premium key already fails. Since the 31 August tier change they answer HTTP 403 with
-32052, and a few answer HTTP 200 carrying-32000 Unauthorized. An HTTP 200 that holds an error is the one worth grepping for, because a client that only checks the status code reads it as success. - Nothing else changes. Every other network keeps its endpoints, its plan, its rate limits and its method list, and no method moved between plans.
If one of these networks is part of how your product works, write to our Sales team at sales@ankr.com before the date and we will look at the options with you.
