Oneflow

Oneflow is a contract lifecycle management and e-signature platform that turns static documents into smart, data-rich digital contracts - covering creation from templates, negotiation, e-signing, and post-sign lifecycle management. The Oneflow Public API is a REST API at https://api.oneflow.com/v1 authenticated with an account API token (x-oneflow-api-token) plus an acting-user email header (x-oneflow-user-email) for permission checks. It lets teams programmatically create contracts from templates, add parties and participants, fill data fields and products, publish contracts for signing, download signed files, and subscribe to contract lifecycle events via webhooks. API access and webhooks are available on the Business and Enterprise plans.

agent ready

Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.

Kin Score

API Evangelist profiles Oneflow the way a machine reads it — 19 machine-readable artifacts across 11 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 — Oneflow scores 40.5/100 (thin), with a separate agent-readiness read of 48/100 (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 Oneflow

Each block below is one kind of artifact we hold for Oneflow. 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 11

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.

Oneflow Comments API

Inline collaboration comments on a contract.

Oneflow Contract Files API

Download the files (PDF / signed documents) attached to a contract.

Oneflow Contracts API

Create, retrieve, update, publish, copy, and delete contracts.

Oneflow Data Fields API

Custom / merge fields on contracts and template types.

Oneflow Participants API

Signatories and viewers belonging to a party.

Oneflow Parties API

Counterparty companies or individuals on a contract.

Oneflow Ping API

Health check and token validation.

Oneflow Templates API

Templates and template types used to create contracts.

Oneflow Users API

Users in an account.

Oneflow Webhooks API

Subscriptions delivering contract lifecycle events to a callback URL.

Oneflow Workspaces API

Organizational containers that scope templates and contracts.

Open Collections 1

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).

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

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.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Cost, billing, and metering signals for API financial operations.

Security Posture 3

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.

Recommended x-agentic-access execution contracts for AI agents.
