This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
Not from the company, and here with a question? You are welcome here — we would rather be the front line and point you the right way than have a good report go nowhere. What this repository can answer is narrow, though, so it is worth knowing who you are actually looking for:
- A question about how the API works, an account, billing, or a bug in the service — that is the company's own support, not us. We profile this API; we do not operate it and cannot see your account.
- A bug in an open-source project we only catalog — file it on that project's own repository. This has happened with a real and correct bug report that reached us instead of the people who could fix it, which helped nobody.
- Anything about this listing itself — the description, the tags, the rating, a missing or wrong artifact — is ours. Open an issue here.
- Not sure, or something general about API Evangelist or APIs.io — open an issue on the APIs.io Inbox and we will route it.
This repository contains no software, and we will never ask you to download anything. There is no build, release, installer, or binary here — only text and machine-readable API descriptions, so there is nothing here that can be "corrupt" or need "repairing". Any issue, comment, or email claiming otherwise and offering a download link is not from us and is hostile. Do not follow the link; it is a lure. Report it to GitHub and, if you like, tell us at info@apievangelist.com so we can take it down.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
ProcessOut is a payments technical layer and orchestration platform that standardizes how merchants connect to 100+ payment providers (PSPs and alternative payment methods). It provides a PCI DSS card vault, tokenization for recurring and one-click payments, dynamic no-code checkout, ML-based smart routing to lift authorization rates and cut cost, plus analytics and transaction reconciliation. The REST API (https://api.processout.com) authenticates with HTTP Basic project keys, supports idempotency keys and webhooks, and ships first-party SDKs for Node.js, Python, Ruby, PHP and Go plus client-side ProcessOut.js and iOS/Android. A hosted MCP server exposes the API and docs to AI agents. Originally a Techstars company, ProcessOut is now part of Checkout.com.

The rubric is published at github.com/api-evangelist/kin-score. The per-check breakdown behind these numbers — which checks were earned, partial or missed — along with score history and how this provider compares to its peers, is available at apis.io/providers/processout/.
API Evangelist profiles a company's public API surface the way a developer would find it: the website, developer portal and documentation, the specifications it publishes, its public repositories, and its pricing, status and changelog pages. From that it derives the properties above — contracts split per API, workflows, schemas, collections, governance rules, plans and rate limits — and scores them against the published Kin Score rubric.
The artifacts are published on APIs.io, not in this repository. This repository is the public record for ProcessOut: the place to say something is wrong, missing or out of date, and to ask for a re-score or a removal.
- Something about this listing — a wrong description, a missing API, a stale artifact or a question about the rating: open an issue on this repository.
- A new API, or one that is not in the catalog yet — submit it on APIs.io.
- Anything else — the APIs.io inbox or info@apievangelist.com.
