Punk API
Punk API is a free, no-auth REST API exposing BrewDog's "DIY Dog" open-source beer recipe collection — 325 detailed homebrew recipes crowdsourced and transcribed from the BrewDog DIY Dog PDF. The v2 surface (api.punkapi.com/v2) offered three read-only endpoints: list beers (with rich query filtering on ABV, IBU, EBC, brew date, beer name, hops, malt, yeast, and food pairing), get a beer by id, and get a random beer. Each beer carries a full recipe — ABV, IBU, EBC/SRM colour, target gravities, mash temperature schedule, fermentation temperature, twist, malt and hop bills, yeast strain, food pairings, brewer's tips, and contributor attribution. STATUS — DEPRECATED. BrewDog decommissioned the public api.punkapi.com endpoint in 2023 and the source repositories (sammdec/punkapi-db, sammdec/punkapi-server) were archived on 2023-06-28. The dataset and server source remain MIT-licensed and available; community-hosted mirrors and the `punkapi-db` npm package preserve the contract documented here.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Punk API the way a machine reads it — 40 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Punk API scores 45.5/100 (developing), with a separate agent-readiness read of 32/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Punk API
Each block below is one kind of artifact we hold for Punk API. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 1
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

Open Collections 3
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

325 BrewDog DIY Dog Recipes
Crowdsourced transcription of the complete BrewDog DIY Dog PDF — every recipe from Punk IPA (#001) through the final published batch.
Full Brewing Recipe
Each beer carries ABV, IBU, EBC, SRM, target gravities, mash schedule, fermentation temperature, malt bill, hop bill, yeast strain, food pairings, and brewer's tips.
Recipe-Oriented Query Filters
List endpoint supports filters on ABV (gt/lt), IBU (gt/lt), EBC (gt/lt), brewed-before/after dates, and substring search on beer name, hops, malt, yeast, and food pairing.
Pagination
page (>=1) and per_page (1-80, default 25) on the list endpoint.
Random Beer
/beers/random returns a uniformly random recipe — useful for "beer of the day" demos.
No Authentication
Fully public — no API keys, OAuth, or signup required.
No Rate Limits Documented
Best-effort public service while it was live. Only the per_page ceiling of 80 is enforced.
MIT-Licensed Source
Both punkapi-db (dataset) and punkapi-server (Express app) are MIT-licensed — self-host or fork freely.
npm Distribution
The complete dataset is published as the `punkapi-db` package for direct in-process use without HTTP.

Semantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

JSON Structure 2
JSON Structure captures the data shapes in a form built for tooling — a complement to JSON Schema that keeps the model machine-legible.

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.

This is an independent, third-party profile of Punk API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
