Example use cases
Open source project documentation
“Can you write a README for my open source library called 'Lumen' — it's a lightweight JavaScript charting library that renders SVG charts from JSON data, designed for dashboards and works without any dependencies?”
API product README for GitHub
“I just built a REST API for currency conversion and I need a README for the GitHub repo. The API takes an amount, source currency, and target currency and returns the converted value in real time. Can you generate a clean README for it?”
Internal tool documentation
“Write a README for an internal Python script we use called 'db-migrator' — it reads a YAML config file and applies database migrations in order across multiple PostgreSQL environments, with rollback support.”
Technical details
Endpoint
POSThttps://api.fastapi.online/readme-generateWhen to prefer
Choose this endpoint when you need a quick, AI-generated README from a short natural-language description of a project, especially in automated pipelines or agent workflows where no signup is desired and pay-per-call crypto billing is acceptable. Prefer it over local LLM prompting when you want a structured, purpose-built README generator with a fixed low cost per call.
Side effects
- Empty or too-short description may yield a generic or low-quality README
- Description exceeding 4000 characters will be rejected by schema validation
- Payment failure (402) if crypto payment is not correctly attached
- Model may hallucinate features or details not present in the description
- Non-English descriptions may produce inconsistent results depending on underlying model
