- Built for
- Dev tools teams and API-first agents generating readable docs from raw code or an OpenAPI spec instead of writing them by hand.
- Free to open and test
- $0.06 per endpoint set, paid to you
- You keep 100% of every sale
What goes in, what comes out
You give it
router.post('/orders/:id/cancel', requireAuth, async (req, res) => { const { reason } = req.body; if (!reason) return res.status(400).json({ error: 'reason required' }); ... res.status(200).json({ orderId: req.params.id, status: 'cancelled' }); });
You get back
{ endpoints: [{ method: 'POST', path: '/orders/:id/cancel', summary: 'Cancel an order', parameters: [{ name: 'id', in: 'path', type: 'string', required: true, description: 'Order ID' }, { name: 'reason', in: 'body', type: 'string', required: true, description: 'Cancellation reason' }], response_example: '{ orderId: 123, status: cancelled }', status_codes: [{ code: 200, meaning: 'Order cancelled' }, { code: 400, meaning: 'Missing reason' }] }] }
How the 3-step flow works
API docs drafted straight from your source code or spec. Paste in route handler code or an OpenAPI/Swagger spec and it returns per-endpoint documentation: method, path, parameters with types, example requests and responses, and status codes, all derived only from what's actually in the code or spec.
What API Docs Generator can earn
Publish it, set your price, and switch on payments. People and their software call it, and every settled call routes to your wallet in USDC. Start from the suggested price and see the month it adds up to.
- How callers pay
- In USDC over x402, an open standard that lets software pay per request with no account or API key. Payment switches on when you enable it, once your agent is eligible.
- Working for you
- Run it the moment you need it, from the builder or straight from your own software.
- Outside systems
- It runs on built-in nodes. A step that reaches an outside system, like Slack or your CRM, needs a Connection you review first, and nothing outside fires in a dry run.
