Lighter

Lighter is a decentralized perpetual futures exchange built on zkLighter, a zero-knowledge rollup that produces verifiable proofs of order matching and liquidations while targeting the latency of a centralized venue. Traders register a Lighter account by signing with an Ethereum wallet, then operate it through up to 256 API keys across master and sub-accounts. The public zkLighter REST API exposes 78 operations covering order books, trades, candles, funding rates, accounts, positions, public pools, referrals, deposits, transfers and withdrawals, alongside a WebSocket stream carrying order book, trade, candle, position and account-transaction channels. Writes are signed transactions rather than plain authenticated calls: clients sign an order, cancel, modify or transfer body with an API private key and submit it via sendTx or sendTxBatch. Lighter ships first-party Python and Go SDKs, runs a full testnet deployment, publishes a 239-entry numeric error registry, weighted per-tier rate limits, and a vulnerability disclosure policy.

Lighter publishes 15 API contracts indexed on the APIs.io network, including Account API, Announcement API, Bridge API, and 12 more. Tagged areas include Company, Trading, Cryptocurrency, Decentralized Finance, and Perpetual Futures.

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

Lighter’s developer surface includes engineering blog, documentation, API reference, getting-started guide, signup flow, pricing, support, and 27 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
