Perp
Perp (Perpetual Protocol) is a decentralized derivatives protocol backed by Multicoin Capital. Its Curie (v2) generation ran on-chain perpetual futures on Optimism via audited smart contracts, a public GraphQL subgraph on The Graph, and an official TypeScript SDK (@perp/sdk-curie). The team has since pivoted to perp.com, a leveraged on-chain prediction-market platform ("perpetual futures for your predictions") offering up to 5x leverage on elections, macro, sports, and cultural outcomes with orderbook-driven, no-expiry positions and funding-rate rebalancing. The perp.com V1 Market Maker API is now documented in detail (a signed WebSocket + REST interface with HMAC-SHA256 auth, bulk order commands, a dead-man switch, private/public WebSocket streams, per-key rate limits, and a full MM_* error registry) though the api.perp.com host is not yet publicly reachable (V1 testnet). The other concrete developer surface is the Curie (v2) GraphQL subgraph, the TypeScript SDK, and the on-chain contract packages published to npm under the @perp scope.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Perp the way a machine reads it — 6 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 — Perp scores 30.4/100 (thin), with a separate agent-readiness read of 39/100 (agent aware). 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 Perp
Each block below is one kind of artifact we hold for Perp. 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.

Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

ASYNCAPISecurity Posture 2
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.
