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.
Redbelly mainnet has been answering on rpc.ankr.com/redbelly_mainnet since late August, and it was missing from the chain list, so the only way to find the endpoint was to be told about it. It is documented now, with its own API reference, and the reference is explicit about the standard EVM methods this node does not implement.
Monad's MONAD_TEN activates on mainnet on 2 September at 14:30 UTC, and our nodes are already on the release that carries it. Sui moved to protocol 135 and Stellar to Protocol 28. On the docs side, the four Agentic RPC pages that moved to a top-level section now answer with a real 301 instead of a page that says 200 and redirects in the browser, and that includes the Markdown twin an agent fetches.
An agent that knows only rpc.ankr.com can now read what the deployment supports and who answers it, without a key and without a second hostname.
The agent-facing pages moved out of Node API into a top-level Agentic RPC section, and gained the two pages they were missing: a quickstart and a troubleshooting guide.
We published the TORPC specification and its reference implementation under open licenses, and the Agent RPC MCP server is now installable from npm.
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.
Nine of these upgrades tracked a hard activation, where a node left on the old version stops following the chain. Taiko's Unzen fork and Somnia's Jig fork both activated inside this window and we landed ahead of both. Monad testnet activated MONAD_TEN on 12 August, and our nodes were already on the release that carries it. Nothing changed in RPC method limits, error codes or rate limits.
Docs now cover the Ankr MCP servers: a read-only data plane that gives an AI agent chain data already decoded and compressed for a context window, and a control plane that manages your account, keys, usage, and notifications from an MCP client.
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.
Docs now cover Verifiable RPC (vRPC): cryptographically signed JSON-RPC and REST responses that prove they came from an approved, unmodified node running inside an Intel TDX hardware enclave. Your client verifies every response fail-closed, so you no longer have to take the operator's word that a reply is genuine.
