Isometric
Isometric is a London- and New York-based carbon removal registry and AI-native certification platform for the industrial economy, founded in 2022 by Eamon Jubbawy (founder of Onfido). It operates the Isometric Registry — a public registry of high-durability carbon dioxide removal (CDR) credits — and Isometric Certify, the supplier-facing platform for project design, lifecycle assessment, measurement reporting and verification (MRV), and GHG statement submission. Isometric publishes scientific protocols across 14 CDR pathways including direct air capture, enhanced rock weathering, biochar, biomass carbon removal and storage (BiCRS), reforestation, mangrove restoration, wastewater alkalinity enhancement, and subsurface biomass storage, with modular sub-components for capture, feedstocks, LCA, and storage. Two public REST APIs are documented and versioned at /v0 — the Certify Data Ingestion API (53 paths, 170 schemas) for supplier MRV workflows, and the Registry API (38 paths, 79 schemas) for credit balances, issuances, transfers, retirements, deliveries, orders, and Stripe checkout. Both speak OpenAPI 3.1.0, share bearer + x-client-secret authentication, run separate sandbox and production environments, and use Relay-style cursor pagination. No official SDKs are published; clients are expected to generate from the OpenAPI specs. An MCP server is available for AI assistant integration. Data providers including CDR.fyi, MSCI, Sylvera, and CEEZER consume the Registry API for real-time CDR market data.
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 Isometric the way a machine reads it — 41 machine-readable artifacts across 35 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 — Isometric scores 39.5/100 (thin), with a separate agent-readiness read of 53/100 (agent ready). 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 Isometric
Each block below is one kind of artifact we hold for Isometric. 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 35
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.

MCP SERVERSecurity 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.

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.
