That post was a snapshot of what a strong profile looks like. This week I went back into Stripe with a different intent. I did not want to profile it again; I wanted to use it to interrogate my own process. Stripe is the model API — if I comb through it operation by operation, where does my profiling still fall short, and can whatever I fix on Stripe become the blueprint for fixing it on everyone else? That reframing is the whole point. A single deep profile is useful. A deep profile that upgrades the process behind every other profile in the network is worth far more. ## The gap I found hiding in plain sight When I read the Stripe profile closely, the omission was almost embarrassing. My profiling captured the *contract* (OpenAPI, schemas, specs) and the *business* (plans, rate limits, FinOps) really well. But an entire tier of the API — the part a developer actually wrestles with on day one — existed in the profile only as bare hyperlinks. Stripe's `apis.yml` had link-style properties for idempotency, pagination, field expansion, metadata, and testing. It pointed *at* those doc pages and captured none of what they said. That is a strange thing to notice on the API that basically *invented* idempotency keys, cursor pagination, and field expansion as industry conventions. The runtime semantics — the how-it-actually-behaves layer — were the least-captured part of the profile for the provider most famous for getting them right. So that became the work: turn that tier into real, structured, forkable artifacts, with Stripe as the reference implementation. ## The new artifacts, drawn from Stripe Going through Stripe's surface with a fine-tooth comb produced seven new artifact types, each one now a first-class part of the profile instead of a link: - **Sandbox / test data.** The single biggest blind spot across the whole network. Nobody's profile captured the test cards, test bank accounts, test-mode key prefixes, test clocks, and trigger fixtures a developer needs to exercise an API without moving real money. Stripe's `4242 4242 4242 4242` and its whole decline-simulation surface are now data in the repo. - **API conventions.** One structured document for the cross-cutting semantics — idempotency, pagination, field expansion, metadata, request IDs, the version header, the error envelope — that OpenAPI does not fully express. - **A structured changelog** of Stripe's dated, release-train versions, as data rather than a link. - **A CLI command catalog** — the actual command surface of the Stripe CLI, not just the fact that it exists. - **An embedded-components catalog** — Elements, Checkout, Payment Element, the Connect embedded dashboards — the client-side UI layer that is distinct from the server SDKs. - **A data model** — a machine-readable entity-relationship graph of the core objects (Customer, PaymentIntent, Charge, Refund, Invoice, Subscription) and how they reference each other. - **A decline-codes catalog** — the issuer-level `decline_code` taxonomy that sits underneath a card error, which is a payments-specific thing but exactly the kind of domain knowledge a profile should carry. While I was in there I also closed two gaps I had left open: a **trust center** artifact capturing Stripe's PCI DSS Level 1 and SOC 1/2 posture, and the **Connect OAuth scopes** that the core key-auth API never exposed in its OpenAPI. ## Making the integrations honest Yesterday's post described "55 forkable integrations." I need to be straight about that: they were forkable in ambition, but they sat in a capability format I had since retired. This week I actually made them what I had claimed. Every integration that had a real partner — one that also publishes OpenAPI in the network — was rebuilt as a **two-source Arazzo workflow** whose every step calls a verified `operationId` in the real spec on *both* ends. Stripe to HubSpot, Stripe to Salesforce, Stripe to Avalara, Stripe to Twilio: 44 of them, forkable and executable, not screenshots of a marketplace. The dozen partners with no spec to point at became honest listing-only entries — I would rather record "we cannot build this faithfully yet" than fabricate an integration. Then I filled the obvious holes in Stripe's own workflows. The existing set covered payments and billing but skipped Stripe's other marquee products, so I added native Arazzo workflows for **Connect onboarding, Issuing, Identity, Financial Connections, saving a card for future payment, Tax, and Quotes** — each one grounded in real operations. And every one of these workflows now has an index, so the collection is browseable instead of being a folder you have to spelunk. ## The part that makes it a blueprint None of this would matter much if it stopped at Stripe. The reason to use the best provider as a template is so the template travels. So the new artifact types went straight into the enrichment contract that drives the whole network, and then I ran the new tier against Stripe's direct peers — the payments cohort: **PayPal, Square, Adyen, Braintree, Plaid, Checkout.com, Razorpay, Wise, GoCardless, and Authorize.Net.** What came back is the best evidence that the blueprint works, because it did *not* come back uniform. PayPal has a 150-plus code processor-response taxonomy; Square's test tokens and Adyen's numbered refusal reasons look nothing like Stripe's; Plaid and Authorize.Net ship real CLIs; Wise, which is not a card acquirer, correctly has no decline taxonomy at all and said so instead of inventing one. A good process meets each provider where it actually is. The rule I held every one of them to was the same rule I hold myself to on Stripe: capture what the provider really publishes, and skip — never fabricate — what they don't. That is what "use Stripe as a blueprint" means in practice. Not copying Stripe's answers onto other providers, but copying the *questions* — does it have a sandbox, what are its conventions, where is its changelog, can its integrations be forked — and letting each provider's real surface fill in the answers. The Stripe profile got deeper this week, but the more durable outcome is that every profile after it starts from a better set of questions. You can browse the readable version at [apis.io/stripe](https://apis.io/stripe) and fork the raw artifacts from [github.com/api-evangelist/stripe](https://github.com/api-evangelist/stripe) — and then ask how many of these your own API could answer today.
