# How to explain confusing API documentation and SDK references on screen.

Stop copy-pasting webhook payloads, rate-limit headers, and OAuth flows into a separate chat tab. Highlight any API spec in Chrome or Firefox and get an on-screen explanation with page context attached.

> **Best fit:** Best for software engineers and technical integrators reading unfamiliar REST, GraphQL, or SDK documentation.

## Live Webpage Walkthrough

- **Source:** Stripe API Reference — Idempotent Requests (`docs.stripe.com/api/idempotent_requests`)
- **Recommended Context Mode:** Detailed

**Highlighted Passage:**
> Results are only saved if an API endpoint started executing. If incoming parameters fail validation, or the request conflicts with another request that is executing concurrently, no idempotent result is saved.

**User Question (Shortcut):** "What does this mean for my retry logic if two webhook workers send the same key at the exact same millisecond?"

**Vezz me On-Screen Answer:**
1. Concurrent collision: One request will proceed and the second will immediately return a `409 Conflict` (or lock error) WITHOUT caching a saved response.
2. Validation failure (`400`): Not cached—you can fix the payload and reuse or rotate the key.
3. Action for your retry worker: Treat `409`/concurrent lock errors as retryable with exponential backoff + jitter using the SAME idempotency key, because the first request is still in flight.

**Suggested Follow-Ups:**
- "Show a TypeScript fetch retry wrapper that handles this exact 409 case safely."
- "How long does Stripe retain idempotency keys before expiring them?"
- "What happens if I send the same idempotency key with different body parameters?"

```text
You are a staff software engineer helping me read technical documentation. Explain the selected spec or code in plain, concrete terms: 1) What it actually does at runtime, 2) Hidden edge cases, failure modes, or concurrency gotchas, and 3) A minimal, production-safe usage pattern. Avoid generic boilerplate.
```

**Why it works:** Forces the AI to translate abstract specification prose into concrete runtime behavior and failure modes.

## Step-by-step workflow

1. **Highlight the exact spec or parameter table**: Select the paragraph, rate-limit note, or SDK method signature that is ambiguous.
2. **Trigger with Detailed page context**: Press Ctrl+Shift+X. Vezz me attaches the page title, URL, and section headings so it knows which API version and SDK language you are viewing.
3. **Ask about edge cases and retry behavior**: Use follow-up questions in the on-screen panel to ask what happens on timeouts, null values, or version upgrades.

## Why API docs are hard to read in a separate chat tab

When you copy a method signature into an external chatbot, you lose the surrounding page headings, authentication assumptions, and SDK version.

- Vezz me automatically includes the documentation page's title, URL, and headings
- The floating panel sits right beside the parameter table so you can cross-check field names
- No tab-switching means you don't lose your scroll position inside long single-page API references

## High-leverage questions to ask on documentation pages

Move past basic definitions and ask questions that prevent production bugs.

- 'What is the difference between this field and [related field] in the same payload?'
- 'Give me a minimal curl or TypeScript example using this exact endpoint.'
- 'What HTTP status codes or error shapes should my caller handle here?'

## Frequently asked questions

### Does Vezz me know which programming language or SDK tab I am looking at?

Yes—when Page Context is set to Basic or Detailed, Vezz me reads the current page title, URL, and surrounding headings alongside your highlighted snippet so answers match the framework on screen.

### Can I copy code snippets directly from the Vezz me answer panel?

Yes. You can copy the entire explanation or code example with one click and paste it straight into your IDE or PR description.
