Ancient8
Ancient8 is a gaming-focused Ethereum Layer 2 blockchain built on the Optimism OP Stack with Celestia for data availability, designed to power Web3 gaming experiences at scale. The network is EVM-equivalent, so developers deploy Solidity smart contracts and dApps using standard tooling (Hardhat, Remix, thirdweb) against a public Ethereum JSON-RPC interface. Ancient8 Mainnet uses chain ID 888888888 with ETH as its gas currency, complemented by a Celestia-backed testnet, native and third-party bridges (Meson, Relay), block explorers (Routescan, Blockscout/A8Scan), a faucet, staking, and a vault. The programmable surface exposed to integrators is the JSON-RPC endpoint over HTTPS and WebSocket. Backed by Pantera Capital and surfaced into the API Evangelist network from its venture portfolio.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Ancient8 the way a machine reads it — 3 machine-readable artifacts across 2 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Ancient8 scores 18.1/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Ancient8
Each block below is one kind of artifact we hold for Ancient8. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 2
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
