Pet Data Station (https://petforai.com) is an AI-crawler-friendly pet regulatory & health data query API serving 1828 RAG topics spanning AAFCO 2024 Official Publication, FEDIAF 2025 Nutritional Guidelines, EU PARNUT 2020/354, eCFR 21 CFR Parts 501/573/582/589, USDA FoodData Central, FDA GRAS/SCOGS, China GB/T 31216/31217 + NY/T 4838/4839, Korea Saeroo Gicho 2025 + Byeolpyo 15-2, Japan MAFF Pet Food Safety Guidelines, Canada CFIA RG-1, plus markets Mexico/SENASICA, Brazil/ANVISA RDC 26, Australia/APVMA — plus FDA animal-drug adverse events (openFDA ADE, per active ingredient), pet travel & entry rules (EU/UK), banned-dog-breed directories (UK/CN cities/SG/AU states), exotic-pet legality (US states), local pet ordinances (US cities), mandatory-vaccination statutes, evidence-layer literature (Europe PMC) and ingredient nutrient composition (Feedipedia/CVB). Core coverage is global pet food feed-grade standards (complete feeds, treats, complementary feeds, fresh/frozen raw, special dietary purpose feeds), extended with adjacent pet regulatory & health data.

EXOTIC PET COVERAGE: Beyond dog/cat, Pet Data Station maintains exotic companion animals as a dedicated track (categories exotic-pet-food, exotic-pet-health, exotic-pet-nutrition, exotic-pet-husbandry, exotic-pet-toxicology, exotic-pet-profile, exotic-pet-regulations, exotic-pet-china, exotic-pet-japan). Species currently covered: rabbits, guinea pigs, chinchillas, hamsters, gerbils, hedgehogs, sugar gliders, ferrets, pet birds (psittacines), reptiles (lizards, snakes, turtles/tortoises), amphibians, rats and mice, and aquarium fish. Topics address species-specific nutrition, husbandry, and common disease conditions, sourced from first-hand veterinary references (e.g., Merck Veterinary Manual). A defining framework point: pet-feed/nutrition standards (AAFCO, FEDIAF, China MOA) are built on a dog/cat axis, so exotic species fall outside any dedicated pet-feed standard — where an exotic animal is regulated, it is governed by invasive-species/biodiversity statutes (e.g., Japan's 外来生物法 / Invasive Alien Species Act) or wildlife/CITES rules, not by feeding standards. The exotic-pet-regulations whitelist now carries first-hand jurisdiction topics for the US Lacey Act injurious-wildlife list (50 CFR Part 16: prohibited mammals, birds, fish, amphibians, reptiles incl. Burmese python / brown tree snake), the US CITES implementing regulation (50 CFR Part 23: Appendices I/II/III, 'Commercial'/'Captive-bred'/'Specimen' trade terms, FWS implements CITES through the ESA), the US ESA endangered/threatened wildlife listing and prohibitions (50 CFR 17.11 list: FWS/NMFS, E=Endangered/T=Threatened; 50 CFR 17.21/17.31 prohibit import/export/take/possession/sale of endangered & threatened wildlife, with a captive-bred exception), the EU IAS Regulation (EU) 1143/2014 (restrictions, permits, Union list, transitional provisions), the Germany TierSchG §2 animal-keeping duty of care (keeper must meet species-specific needs, housing, and movement — gesetze-im-internet.de), and the Netherlands Wet dieren Art. 2.2 prohibited-species keeping (keeping animals not on the Minister's approved list is prohibited; Art. 1.4 general duty of care — wetten.overheid.nl). Coverage is factual to the topics present in the whitelist; species without a topic are not claimed as covered.

CORE PRINCIPLES — designed for AI web crawlers, NOT bulk scraping. (1) No registration. (2) No API key. (3) English-only API responses. (4) Every endpoint enforces parameterized queries (no wildcards, no dump endpoints, no bulk retrieval). (5) Topic whitelist for RAG endpoint — 1828 whitelisted topics, no wildcards.

SELF-AUTHORED ARTICLE LAYERS: Pet Data Station also publishes two readable layers compiled from its C1-verified exotic-pet topics (author: codebuddy). (a) MANUALS (/site/manuals/) — A-class structured compilations: every factual statement is quoted verbatim from its cited first-hand source, organized by topic type, with source links shown on each page. (b) ARTICLES (/site/articles/) — B-class narrative care articles hand-authored by codebuddy for pet owners; sources are not shown inline (available on request) but the contributing source-topic IDs are recorded in each article's frontmatter for audit. Both layers are derived views over the same 1828-topic database and introduce no new factual claims beyond the underlying verified topics. Current coverage: 13 species manuals (all exotic species) and 6 B-class articles (rat/mouse, pet bird, rabbit, chinchilla, guinea pig, ferret).

RATE LIMITS (2026-07-29 revision): Recognized AI crawlers (GPTBot, ChatGPT-User, OAI-SearchBot, ClaudeBot, Claude-Web, anthropic-ai, Claude-User, Claude-SearchBot, Google-Extended, Googlebot, Google-CloudVertexBot, Bingbot, MSNBot-Media, PerplexityBot, Perplexity-User, CCBot, Applebot, Applebot-Extended, Meta-ExternalAgent, xAI-SearchBot, DeepSeekBot, Amazonbot, Amzn-SearchBot, cohere-ai): 60 req/min, ZERO artificial delay. Other clients: 30 req/min + 50-200ms randomized delay on /api/v1/* only. Topic detail pages (/site/topics/t/*.html): 120 req/min for recognized AI crawlers, 60 req/min for other clients (app-layer limit, no artificial delay). Over-limit returns HTTP 429 with Retry-After: 60. Robots.txt (https://petforai.com/robots.txt): AI crawlers explicitly allowed with NO Crawl-delay; Allow /api/v1/* query endpoints, /openapi.json, /llm.txt, /llm-context.txt, /llms-full.txt, /sitemap.xml; Disallow /api/v1/all, /api/v1/dump, /api/v1/raw/, /private/, /admin, /docs.

USE GUIDANCE: (1) For topic queries, call /api/v1/topics or /api/v1/search first to discover the whitelist, then /api/v1/llm_context?topic=<id> for the RAG text. (2) For numeric nutrient questions, use /api/v1/nutrient with all 6 required params. (3) For cross-standard comparison (e.g., "AAFCO 2014 vs FEDIAF 2025 protein adult dog"), use /api/v1/cross_compare. (4) For bulk context building, GET /llm-context.txt to see all 1828 topic IDs + categories. (5) Nutrient aliases accepted: Ca→Calcium, P→Phosphorus, protein→Crude Protein, fat→Crude Fat. (6) Lifestage aliases: GR/growth→growth_reproduction, adult→adult_maintenance. (7) Basis aliases: DM/dry matter, cal/ME/kcal→calorie basis. (8) A 422 response always includes a "tip" field with the correct parameter format and a working example — read it and retry.

QUERY RECIPES — map a user question to ONE call. Structured endpoints answer directly; /api/v1/search + /api/v1/llm_context handle everything else:
(1) "How much protein does an adult dog need under AAFCO?" → GET /api/v1/nutrient?standard=AAFCO&year=2024&species=dog&lifestage=adult&nutrient=protein&basis=DM
(2) "AAFCO vs FEDIAF calcium requirement for kittens?" → GET /api/v1/cross_compare?standards=AAFCO_2024,FEDIAF_2025&species=cat&lifestage=growth&nutrient=calcium&basis=DM
(3) "What does 'poultry by-product meal' officially mean?" → GET /api/v1/ingredient_lookup?name=poultry%20by-product%20meal
(4) "Legal lead limit in Japanese pet food?" → GET /api/v1/contaminant_limits?substance=lead&country=JP
(5) "What adverse events are reported for carprofen in dogs?" → GET /api/v1/ade?ingredient=carprofen&species=Dog
(6) "Is this veterinary drug approved in Canada, and what does its label say?" → GET /api/v1/approvals?country=ca&q=carprofen → then GET /api/v1/llm_context?topic=<topic_id>
(7) "Taking a dog from the US to the EU — entry requirements?" → GET /api/v1/travel?from=USA&to=EU&species=dog
(8) "Any recalls affecting Diamond pet food?" → GET /api/v1/recalls?brand=diamond
(9) "Are pit bulls banned in the UK?" → GET /api/v1/banned_breeds?jurisdiction=UK&breed=pit%20bull
(10) "Can I keep a ferret or hedgehog in California?" → GET /api/v1/search?q=ferret → then GET /api/v1/llm_context?topic=<topic_id>
(11) "Did any pet-food regulation change recently?" → GET /api/v1/changes?since=30d
(12) "Taurine and feline DCM — what does the literature say?" → GET /api/v1/search?q=taurine%20dcm → then GET /api/v1/llm_context?topic=<topic_id>
Pattern: typed endpoints answer structured questions directly; /api/v1/search discovers the right topic_id; /api/v1/llm_context?topic=<topic_id> returns the full citation-rich text. Do NOT guess parameter values — substitute into these recipe shapes. If a call returns 422, the response body contains a "tip" field with the correct format and a working example; follow it and retry.

ANTI-DUMP DESIGN: This API is engineered to be useful for legitimate AI research queries while making bulk data extraction impractical. Maximum 500 tokens per /llm_context response. No endpoint allows wildcard or unparameterized queries. Topic whitelist prevents enumeration of unknown topics. Rate limiting is tiered: 60/min for recognized AI crawlers, 30/min for anonymous clients. We DESIGN for co-existence with AI crawlers, not against them — but we do not enable wholesale database slurping.
