Gunzilla Games

Gunzilla Games is a AAA game developer founded in 2020 with studios in Frankfurt, Kyiv and London, best known for the cyberpunk battle-royale shooter Off The Grid. Alongside the game the studio operates GUNZ, a permissioned Avalanche L1 (subnet) blockchain purpose-built for game developers, with GUN as its native gas coin. The public technical surface is EVM-shaped: a public Ethereum/Subnet-EVM JSON-RPC node at rpc.gunzchain.io (chain ID 43419), a mirrored Avalanche-hosted RPC, and the GUNZScan block explorer at gunzscan.io, which exposes a Blockscout REST v2 API, an Etherscan-compatible module/action API, an open GraphQL endpoint and a WebSocket subscription surface. A gated marketplace/minting API sits behind api.gunztoken.io.

Gunzilla Games publishes 2 APIs on the APIs.io network. Tagged areas include Company, Gaming, Blockchain, Web3, and EVM.

The Gunzilla Games catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Gunzilla Games’ developer surface includes documentation, API reference, engineering blog, support, authentication, sandbox, and 23 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/gunzilla-games: open an issue to ask a question, or submit a pull request to add artifacts.

  description: The public Ethereum-compatible JSON-RPC endpoint for the GUNZ L1 chain, an Avalanche subnet running Subnet-EVM.
    It inherits the full EVM API surface of an Ethereum node (eth_*, net_*, web3_*), plus the Avalanche subnet-evm extensions.
    Chain ID 43419, native gas coin GUN (18 decimals), Snowman++ consensus, ~1-2 second blocks with finality in 2-3 blocks.
    The chain is permissioned for contract deployment and validation; the RPC itself answers anonymous reads, with IP allow-listing
    offered to partners to avoid rate limits.
