Definition Workflow Stripe API-First
stripe
Stripe API-first methodology. Documentation as product, precise contracts, developer-centric specs where writing IS the product.
Inspired by Stripe API-First.
The methodology is its originators’ own published work, drawn from their public
writing and talks. ProductBuildersHQ has implemented it as a machine-readable workflow
in
VisionSpec
so it can be automated — spec synthesis
and LLM-as-a-Judge evaluation, built in.
This encoding is an independent interpretation, not affiliated with or endorsed by its originators.
Specs in This Workflow
Methodology Principles
Contract First API design precedes implementation; the spec IS the source of truth
Docs As Product Documentation is a first-class product, not an afterthought
Developer Empathy Every spec is written from the API consumer's perspective
Precision No ambiguity; every input, output, and error is explicitly defined
Consistency Patterns are predictable across the entire API surface
Versioning Discipline Breaking changes are managed with care and clear migration paths
Externally Legible Specs should be readable by external developers, not just internal teams
Code As Documentation Examples and SDKs are integral to the spec, not supplementary
Included Assets
10 document templates · 10 LLM-as-a-Judge rubrics — embedded in visionspec.
