Higher RPC rate limits with API keys

June 20, 2026DEVNETTESTNETRPCSDK

API keys are now available to raise RPC rate limits — supported by devnet and testnet RPC and all seven Phantasma SDKs.

Devnet and testnet RPC now support API keys that grant higher rate-limit tiers: node operators can issue keys for higher-volume access, and can optionally run a node in keys-only mode.
All seven Phantasma SDKs can now attach an API key to the RPC client, so requests use the matching rate-limit tier on nodes that issue keys.
The same RPC build returns NFT lookups that find nothing as a clean not-found result instead of surfacing as an error.
Controlled API errors now propagate with their intended status and message instead of being flattened by a catch-all handler.
Updated SDK packages: phantasma-sdk-ts 0.11.0 (TypeScript), phantasma-sdk-py 2.2.0 (Python), phantasma-sdk 1.2.0 (Rust), phantasma-sdk-go v0.11.0 (Go), and PhantasmaPhoenix.RPC 0.8.0 (.NET), plus updated C++ and Unity SDKs.
