API Documentation

Let developers ask
your documentation.

Like having a senior dev who read every page. Natural language questions, verified answers with source links.

Like having a senior dev who read all your docs

Developers ask questions in plain English. They get precise answers with links to the source.

Dev

"How do I handle rate limiting in the payments API?"

"The payments API returns HTTP 429 when rate limited. Implement exponential backoff starting at 1 second, with a maximum of 3 retries. The Retry-After header contains the wait time in seconds."

Confidence: 96% Source: payments/rate-limiting.md

Dev

"What's the maximum payload size for webhooks?"

"Webhook payloads are limited to 64KB. Events exceeding this limit are truncated. Use the GET /events/{id} endpoint to retrieve the full event data."

Confidence: 91% Source: webhooks/limits.md

Why not just use ChatGPT?

ChatGPT is great for general questions. For your specific documentation, you need something grounded.

ChatGPT / generic AI

✗ Trained on old versions of your docs
✗ Confidently invents API methods that don't exist
✗ No source links — developers can't verify
✗ Generic — doesn't know your specific setup

Wauldo

✓ Always current — answers from your latest docs
✓ Never invents — refuses when unsure
✓ Source links on every answer
✓ Your docs only — no external data
