Dataset contract

The product is structured data. The site is the distribution channel. Everything below is served as immutable static JSON at https://errors.standardbeagle.com/data/… — CORS-enabled, so browsers and third-party tools can fetch it directly.

Search API

A thin edge function wraps the same tiered matching the MCP server uses (exact code → derived pattern → fuzzy). All responses are JSON with Access-Control-Allow-Origin: *.

Endpoint	Purpose
`GET /api/search?q=<message>`	Scored matches for a raw error message. Optional `repo=owner/name`, `limit` (max 25).
`GET /api/errors/{id}`	Full ErrorEntry record by id.
`GET /api/repos`	Analyzed repositories with error counts.

curl "https://errors.standardbeagle.com/api/search?q=Request+failed+with+status+code+404"

Prefer bulk or offline consumption? Skip the API — download the dataset files below and query locally; that is exactly what the MCP server does.

Files

Path	Purpose
`/data/manifest.json`	Freshness poll target. Tiny. MCP checks this first.
`/data/index.json`	Compact search index — one record per error, all repos.
`/data/repos.json`	RepoEntry[] — the list of analyzed repos.
`/data/repos/{owner}/{name}.json`	Full ErrorEntry[] for one repo.
`/data/errors/{id}.json`	A single full ErrorEntry record.

Schema

JSON Schema (Draft-07): /schema.json. TypeScript types: @errlookup/schema. Every record validates on write, on read (build), and on download (MCP). Fail fast; never silently coerce.
