Partner API and Developer Documentation for Your SaaS
I get your API ready for outside developers: API keys, rate limits, versioning, signed webhooks, and a docs site partners can build against without emailing you. It is for SaaS teams opening their product to partners, marketplaces or customers. Prices start from $780 ($600 founding), and the work takes about 2–5 weeks.

Who this is for.
A good fit if
- SaaS products with a partner, reseller or marketplace integration on the way.
- Teams whose API works but whose docs are a wiki page and a Postman export.
- Founders who get the same integration questions every week.
Common triggers
- A marketplace or partner requires a documented, versioned API.
- A breaking change broke a customer’s integration.
- Support time spent explaining the API.
Not a fit if
- You don’t have a working API yet. Start with Technical Spec & API Design or Backend APIs.
- You need a large developer portal suite with SSO, billing and analytics.
What I do, and what you get.
What I do
- Audit the existing API for consistency, errors and auth.
- Write the OpenAPI 3.1 file for the public surface.
- Write guides: quick start, authentication, errors, pagination, webhooks, changelog.
- Publish a docs site with an interactive reference.
- Standard/Plus: add API keys with scopes, rate limits, versioning and deprecation rules, and signed webhooks.
- Test every docs example against a real environment.
What you get
- An OpenAPI 3.1 contract in your repo.
- A docs site (static, hosted with your app or on your hosting) with a quick start and guides.
- Verified code examples (curl plus one language).
- A versioning and deprecation policy, and a changelog.
- Standard/Plus: key management, rate limits and webhooks in your code, with tests.
- Handover notes.
Your part
- Repo access and a staging environment with test data.
- A decision maker for what’s public and what stays private.
- Hosting for the docs site (or use your app’s).

Founding price: 3 of 7 spots left, until Mar 31, 2027 — one-off work, in return for a testimonial. How it works
Prices are in USD, paid by bank transfer against an invoice. Work under $1,000 is paid upfront; larger work is 50% to start and 50% before handover, or monthly milestones. How working together works
Variations

How it runs.
- 01
Email the template
Email the template below, and I reply within 1 US business day.
- 02
Audit and proposal
I audit the API and send a proposal.
- 03
Contract and guides
I write the contract and guides, then you review them.
- 04
Code and testing
I make the code changes (Standard/Plus) with tests, and test the docs on staging.
- 05
Publish and hand over
I publish the docs site and hand everything over.
Where I have done this before.
Questions buyers ask.
Which docs tool?
Usually Scalar or Redoc for the reference, with Markdown guides. It’s static and cheap to host.
Will you support our partners?
Not on call. A care plan or hours block covers questions and updates.
How do you handle breaking changes?
With a versioning rule, deprecation headers, a changelog and a notice period.
Do you generate SDKs?
One in the Plus plan, generated from the spec and tested.
Do examples really work?
Yes. Every example is run against staging before publishing.
Ask about Partner API & Developer Docs.
Tell me what you have and where it hurts. I reply within one US business day with either a fixed quote or the entry step that makes a fixed quote possible.

More in Product & API Design
Technical Spec & API Design
I write the build-ready specification for your app or API: endpoints, request and response shapes, errors, auth, webhooks, workflows and admin screens, as an OpenAPI 3.1 contract plus plain-English docs. It is for founders and teams handing work to developers. Prices start from $650 ($500 founding), and a spec takes about 1–3 weeks.
AI Agent Interface (MCP Server)
This is a new service. I build a Model Context Protocol (MCP) server so AI assistants such as Claude or ChatGPT can use your product through your existing API. It starts read-only, and writes need the user’s confirmation. It is for SaaS teams with a working API. Prices start from $960 ($720 founding), taking about 2–5 weeks.
