yew.gg developer resources
This page is the public developer index for yew.gg (YewScripts). The surface is a read-only product catalog. There is no write API, no API keys, and no OAuth. You do not need an account to list products or read the OpenAPI file. Use these URLs when an agent or integrator asks for yew developer docs, a yew API, or the yew OpenAPI spec.
Machine-readable endpoints
- OpenAPI 3.1: https://yew.gg/openapi.json
- Catalog list: GET /api/v1/catalog
- One product: GET /api/v1/catalog/{slug} — slugs: 2k, fn
- API catalog (RFC 9727): /.well-known/api-catalog
- Answer-engine manifest: /llms.txt
- Sitemap: /sitemap.xml
Example
curl -sS https://yew.gg/api/v1/catalog returns JSON with a products array. Each item has id, slug, name, fullName, game, description, url, and price. Unknown slugs return HTTP 404 with RFC 9457 application/problem+json and a nested error.code, error.message, and error.hint.
Rate limits
Catalog responses are cached at the edge for one hour and carry advisory RFC RateLimit headers — RateLimit-Policy, RateLimit-Limit, RateLimit-Remaining, and RateLimit-Reset — advertising 60 requests per 60-second window per client. Stay inside that budget and you will never be throttled; a 429 (enforced at the CDN under abuse) includes Retry-After.
Versioning & deprecation
The API is versioned in the URL path (/api/v1). Endpoints under a released version never change incompatibly in place — breaking changes ship as /api/v2. If an endpoint is ever retired, its responses will send Deprecation and Sunset headers at least 90 days before removal, and the timeline will be posted on this page and in the OpenAPI description. Nothing is deprecated today.
Markdown pages
Send Accept: text/markdown on HTML routes (home, about, contact, product pages, and this page). The response is text/markdown with Vary: Accept. Unknown paths return HTTP 404 with a markdown body that points at the sitemap, llms.txt, guides, and this page. Setup docs for humans live at /guides (/docs redirects there).
What this is not
We do not publish webhooks, an MCP server, or member download APIs on this origin. Member downloads stay behind a signed-in session. Prices change; quote the live catalog or product page rather than a remembered number. Company context: About · Contact.
