How this service works
Obol: Description → OpenAPI spec + Hono server → GitHub PR — $5 USDC
Output
Returns the URL of the opened pull request on a fork of the target repo, the fork URL, the branch name, and a list of file paths written — including the generated OpenAPI spec and Hono server files.
Example use cases
Scaffold new microservice from description
“I need to build a microservice for handling user notifications — it should support creating, reading, updating, and deleting notification preferences, plus an endpoint to send notifications via email or SMS. Can you generate an OpenAPI spec and Hono server for it and open a pull request on my repo acme-org/notifications-service?”
Auto-generate e-commerce API boilerplate
“We're starting a new e-commerce backend and I need a REST API that handles products, inventory, orders, and payments. Can you take that description, generate a full OpenAPI spec and Hono TypeScript server scaffold, and submit it as a pull request to our GitHub repo acme-org/shop-api so the team can review it?”
Generate API spec for internal analytics
“I want to expose an internal analytics API that lets teams query event counts, funnel metrics, and retention data filtered by date range and user segment. Please generate an OpenAPI spec and a Hono server implementation from that description and open a PR on acme-org/analytics-api for me to review.”
Technical details
Endpoint
POSThttps://api.obol.sh/api?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to go from a plain-English API description to a working OpenAPI spec plus a Hono TypeScript server scaffold, delivered directly as a GitHub PR. Prefer this over generic code generation tools when you want the result committed to a specific repository automatically rather than returned as raw text.
Side effects
- Invalid or inaccessible GitHub repo (owner/repo not found or no permissions) — PR creation fails
- Insufficient payment or payment not sent via x402 protocol — 402 response returned
- Malformed or too-vague description causing generation to fail — partial or empty file output
- Invalid email format causing notification delivery failure
- GitHub API rate limiting or downtime preventing fork or PR creation
