Service 01
API Documentation Services
A reference a developer can build against on their own. Every endpoint, every error, every example tested before it ships.
Paperkraft's API documentation services cover the full reference: endpoints, authentication, errors, rate limits, and tested code samples -written by people, verified against your live API, and shipped in the docs tool you already use.

What we deliver
A reference developers trust on the first read
Endpoint reference
Every method with a real description, typed parameters, and complete request and response pairs. Generated from your spec, then written by a person.
Tested code samples
Four or more languages per endpoint, each one executed against your live API before publish. If it doesn’t run, it doesn’t ship.
Auth, errors & limits
The three things every integration hits and most docs skip. A full error catalog with what causes each one and what to do about it.
Built for agents too
Structured so Cursor, Copilot and ChatGPT quote your API correctly.
llms.txt shipped by default, because they read your docs before your users do.
“How do I paginate results?”
Pass cursor from the previous response until it returns null.

Works with your stack
We write into what you already run.
No migration required. If you have no setup yet, we pick one and stand it up.
What’s included
Every project ships with all three
Clear structure
We map the pages before we write them, so readers find things fast instead of hunting. This is where most docs go wrong.
Clear, accurate writing
Short sentences. One idea per page. Written by people who have shipped software, then checked against your product. So it is correct, not just readable.
Design & UX
A portal that looks like your product and works on a phone. Clean navigation, real search, nothing to fight with.
Stays current
Docs that ship with the release, not after it
We wire your reference to your spec, so an API change opens a docs change automatically. Nothing drifts quietly out of date.
01 · Spec changes
A field is added to your OpenAPI spec on merge.
02 · Diff opens
The affected pages and samples are flagged, not the whole site.
03 · We write
A human writes the description and re-runs every sample.
04 · Published
Live the same day the release goes out, versioned and dated.
Questions
Before you ask
- 01
We already generate docs from our spec. What do you add?
A generator gives you field names. We add the sentence that says what a field is for, when to use the endpoint, what happens when it fails, and an example that actually runs.
- 02
Do you need access to our API?
A sandbox key is enough. We test against it rather than describing behaviour we have not seen, and we sign an NDA before anything is shared.
- 03
How much engineering time does this take?
A kickoff, a sandbox key, and review passes on drafts. Your engineers confirm accuracy; they never have to write the pages.
- 04
What happens after launch?
We stay on the release cycle. Every change to your spec opens a docs change, and you get a monthly note on what shipped and which questions stopped coming in.
