Approve.com
Approve.com is a cloud-based procurement platform founded in 2019 in Israel that lets businesses stand up a proper purchase-order process quickly, streamlining purchase requisitions, multi-step approvals, real-time budgets, and vendor onboarding with real-time spend controls and insights. Tipalti acquired Approve.com in April 2021 and now operates it as Tipalti Procurement (Tipalti Approve). Its Procurement REST API is still served from the approve.com domain (production https://triggers.approve.com, sandbox https://triggers.sandbox.approve.com), authenticating with an x-api-key header and exchanging JSON with ISO 8601 dates; the purchase-orders API exposes GET and Update purchase-order operations so an external system can stay in sync with Tipalti.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Approve.com the way a machine reads it — 3 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 — Approve.com scores 17.5/100 (emerging), with a separate agent-readiness read of 10/100 (human only). 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 Approve.com
Each block below is one kind of artifact we hold for Approve.com. 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 1
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.

Security 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.
