Ledger Investing
Ledger Investing is a New York-based specialist broking and advisory firm for casualty insurance-linked securities (ILS), connecting insurers, reinsurers and fronting carriers to institutional capital markets investors. The firm originates casualty risk, structures off-balance-sheet solutions, brokes and distributes the resulting securities, and supports secondary trading, having securitized more than $2.5 billion of casualty premium across 170+ transactions since graduating Y Combinator in 2017. Its wholly owned SaaS subsidiary Korra Tech, LLC operates the Korra open data and analytics platform for the reinsurance and ILS market, whose Ledger Analytics API gives actuaries programmatic remote-compute access to Bayesian loss development, tail and forecasting models over insurance loss triangles, alongside the open-source Bermuda (loss triangle manipulation) and BayesBlend (Bayesian model stacking) Python libraries. Other subsidiaries include Ledger Capital Markets, LLC (SEC-registered broker-dealer, FINRA/SIPC member) and Ledger Risk Markets, LLC (licensed reinsurance intermediary).
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Ledger Investing the way a machine reads it — 18 machine-readable artifacts across 1 API, 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 — Ledger Investing scores 53.6/100 (developing), with a separate agent-readiness read of 21/100 (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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Ledger Investing
Each block below is one kind of artifact we hold for Ledger Investing. 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 6
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.
Ledger Investing Cashflow Models API
Cashflow models composed from a fitted development model and tail model.
Ledger Investing Development Models API
Bayesian loss development models (ChainLadder, TraditionalChainLadder, ManualATA, MeyersCRC, GMCL).
Ledger Investing Forecast Models API
Forecasting models (AR1, SSM, TraditionalGCC).
Ledger Investing Tail Models API
Tail development models (GeneralizedBondy, Sherman, ClassicalPowerTransformTail).
Ledger Investing Tasks API
Poll the status of asynchronous fit and predict tasks.
Ledger Investing Triangles API
Upload, list, retrieve and delete insurance loss triangles.
Open Collections 7
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.
Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

Security Posture 4
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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.

This is an independent, third-party profile of Ledger Investing, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
