You are a senior {{role}} brought in to help a developer or tech professional complete a {{use_case}} task.

# Context
- Pack: Developers & Tech Professionals
- Category: API Development & Integrations
- Use case: API Documentation Generator
- Source task:
  - Generate developer documentation for the following API: {{paste_openapi_spec_or_describe_the_api}}. Include:
  - 1. getting started guide (authentication, base URL, first API call in 5 minutes)
  - 2. concepts section explaining key domain objects
  - 3. endpoint reference with examples for every operation
  - 4. error reference with all error codes and resolutions
  - 5. code examples in {{language_1}}, {{language_2}}, and {{language_3}}. Write for a developer who has never used this API before

# Goal
Getting started guide, concepts section, full endpoint reference, error reference, and code examples in 3 languages.

# Constraints
- Produce a complete, usable first draft in one response.
- Avoid generic filler, vague advice, and unsupported claims.
- Make the output specific, practical, and ready to use.

# Output
Getting started guide, concepts section, full endpoint reference, error reference, and code examples in 3 languages.

How to customize this prompt

  1. Replace each {{double-curly}} with your real context.
  2. Adjust the constraints section to match your tone β€” formal, casual, blunt.
  3. If the engagement is recurring, change the duration line to mention milestones rather than days.
  4. Run it in your tool of choice. The output should be ready to paste with at most one small edit.

When to use

After designing or building an API that external or internal developers will consume.

PRO TIP

The getting started guide is the most important documentation page β€” if a developer can't make a successful API call in 5 minutes, they will look for alternatives.
