SDKs
Typed clients, package metadata, tests, examples, and release notes shaped around your API conventions.
Maintained OpenAPI artifacts
Developer artifacts from OpenAPI, kept current.
SDKs, docs, MCP servers, and CLIs generated with reviewable diffs, release plumbing, and portable handoff.
No black box
spec, config, output, and diffs stay visible
No platform sprawl
artifact maintenance without a broad DevEx suite
No reset tax
pricing follows the familiar generator model

Pricing starts with a simple generator model: one maintained artifact, one visible monthly price.

The artifact work your product team keeps inheriting.
ResponsibleAPI keeps generation, package release, docs drift, and runtime edge cases moving without asking your product engineers to babysit routine output.
Docs
Reference pages, usage guides, snippets, and changelog copy generated from the same source.
MCP servers
Tool surfaces derived from real operations, with names and schemas engineers can review.
CLIs
Command surfaces for customers and support teams who need repeatable workflows outside the browser.
source to release
Keep every handoff inspectable.
The point is not to hide generation. The point is to make the routine work explicit enough that your engineers can trust it, review it, and leave it alone.
V
Validate
We check the spec, auth model, pagination, and names before generation starts.
G
Generate
Artifacts are produced from OpenAPI with config and templates that remain inspectable.
R
Review
Your team sees diffs, risky changes, package impact, and release notes before publish.
M
Maintain
Regeneration, publishing, runtime fixes, and documentation drift become a managed loop.
Built for handoff, not lock-in.
Portable output
Generated code, config, docs, release notes, and diffs remain legible. Your team can inspect the pipeline instead of trusting a hosted mystery.
Maintenance that names the work
Auth quirks, pagination fixes, package publishing, docs drift, and runtime compatibility are explicit responsibilities, not bundled into vague platform claims.
A narrower promise
ResponsibleAPI focuses on the artifact pipeline. It does not ask you to replace your API design process, docs stack, or customer support flow.
Generator pricing, plainly stated.
Start with the old generator model: each maintained SDK, docs site, MCP server, or CLI has a clear price. Larger specs and heavier support move up by scope.
Starter
per generator
$79/mo
For small APIs and low-touch maintained artifacts. Includes monthly regeneration, async support, and a clear endpoint cap.
Pro
per generator
$499/mo
For public packages and active API change. Includes CI regeneration, publishing support, custom-code allowance, and priority fixes.
Enterprise
500+ endpoints or procurement
Custom
For larger specs, security review, SSO, SLAs, audit needs, and dedicated support paths.
Send the spec. Get the artifact risk list.
The audit returns what can be generated cleanly, what needs custom handling, which packages need release plumbing, and where maintenance cost will appear.
