Purchaser

Purchaser is an AI-powered RFQ (Request for Quotation) intelligence platform for capital-intensive industries such as EPC, LNG, transmission & distribution, and specialty-equipment manufacturing. It ingests unstructured vendor quotes from PDFs, emails, and spreadsheets and normalizes them into structured, defensible sourcing data so procurement teams can level bids apples-to-apples, surface deviations and gaps, and produce audit-ready award traceability. Purchaser exposes a REST API (OpenAPI 3.1) covering the full sourcing lifecycle — RFQs, vendors, conversations, quotes, files, and webhooks — with API-key auth, idempotency keys, versioned /api/v1/ endpoints, sliding-window rate limiting, and connectors for SAP S/4HANA, Oracle ERP Cloud, Microsoft Dynamics 365, Infor, and more. Based in Lexington, KY and backed by Homebrew.

agent aware

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 Purchaser the way a machine reads it — 6 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 — Purchaser scores 30.5/100 (thin), with a separate agent-readiness read of 36/100 (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.

How we profile Purchaser

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

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

AsyncAPI definitions for this provider's event-driven and streaming APIs.

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.
