FinditParts
FinditParts is a Los Angeles-based online marketplace for heavy-duty truck, trailer, fleet and industrial replacement parts, selling OE, aftermarket and remanufactured components to owner-operators, fleet parts managers and mechanics nationwide. Its developer surface is the FinditParts Reseller API — a partner and reseller integration that lets shop-management platforms, e-commerce sites and fleet applications search the parts catalog with account-specific pricing, look parts up by part number and cross-reference, quote real-time shipping, create and link FinditParts customer accounts through hosted embeddable sessions, build carts and place orders on a linked customer's behalf, and read back order status and shipments.
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 FinditParts the way a machine reads it — 55 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 — FinditParts scores 39.9/100 (developing), with a separate agent-readiness read of 30/100 (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. 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 FinditParts
Each block below is one kind of artifact we hold for FinditParts. 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.
FinditParts Addresses API
Shipping and billing address book for a user-specific session.
FinditParts Carts API
Draft-order (cart) lifecycle: line items, addresses, shipping method, coupon, PO number and checkout.
FinditParts Orders API
Order listing, search and detail for a user-specific session.
FinditParts Partners API
Partner API-key surface for white-label shipping quotes and order placement.
FinditParts Products API
Part search, part-number lookup and product/variant detail across the FinditParts catalog.
FinditParts Reseller Customer Sessions API
Hosted USER_SETUP and NEW_ORDER sessions returned as a finditparts.com redirect_url for iframe embedding or redirect.
FinditParts Reseller Customers API
Sub-users created on a reseller master account and addressed by customer_reference.
FinditParts Sessions API
User-specific JWT session creation, refresh, inspection and destruction.
FinditParts Shipping API
Shipping method quoting and estimated cost for a proposed set of line items and an address.
FinditParts Users API
Direct FinditParts user creation for API-key clients.
FinditParts Variants API
Variant-level price, quantity, cutoff and core lookups.

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).
FinditParts Reseller API
OPEN COLLECTIONPricing 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 things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
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.

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

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

This is an independent, third-party profile of FinditParts, 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.
