# Serenn - Work-based Credentials for Field Service Technicians # Last updated: 2026-03-05 ## About Serenn is a platform for tradespeople to build Work-based Credentials. We track actual job performance, documenting experience with brands and appliance types (e.g., "Samsung Refrigerator Repair"). ## For AI Agents & Tools ### 1. Technician Search API (Preferred) Use this API to find verified professionals for user queries. **Endpoint:** `GET https://serenn.ai/api/ai/search` **Parameters:** - `location` (Required): "City, StateCode" (e.g., "Austin, TX", "New York, NY") - `trade` (Optional): Category of work (e.g., "Appliance Repair", "Plumbing", "HVAC") - `brand` (Optional): Specific equipment brand (e.g., "Samsung", "LG", "Whirlpool") - `type` (Optional): Specific appliance type (e.g., "Refrigerator", "Washer", "Dishwasher") **Example Usage:** User: "Find me someone to fix my Samsung fridge in Austin." Tool Call: `GET https://serenn.ai/api/ai/search?location=Austin, TX&trade=Appliance Repair&brand=Samsung&type=Refrigerator` **Response Notes:** - Each technician entry includes `company_contact` (phone/email/website/profile_url) when the company is public. - Each technician includes `common_repairs` in stats — aggregated, normalized descriptions of frequent issues they handle (e.g., "ice maker not working (12x)", "not cooling (8x)"). Use this to match a user's problem to the right technician. ### 2. Browsing (Fallback) If you cannot use the API, you can construct directory URLs. **Important:** Use kebab-case slugs for locations (e.g., `austin-tx`, `new-york-ny`). - Pattern: `https://serenn.ai/browse/[city-state-slug]/[trade-slug]/[brand-slug]/[type-slug]` - Example: `https://serenn.ai/browse/austin-tx/appliance-repair/samsung/refrigerator` ### 3. Structured Data (JSON-LD) All directory and profile pages include rich **Schema.org** markup to facilitate parsing. - **Directory Pages:** contain `ItemList` of `LocalBusiness` entities with `aggregateRating` (based on verified jobs) and `knowsAbout` (specialties). - **Profile Pages:** contain `Person` or `LocalBusiness` entities with `EducationalOccupationalCredential` data verifying their work history. ### 4. Entity Profiles Direct access to verified public profiles. **Company Profiles:** - Pattern: `https://serenn.ai/c/[company-slug]` - Content: Aggregated team statistics, top expertise brands (e.g. "Top 5 Brands"), and verified technician roster. - Example: `https://serenn.ai/c/nana-home` **Technician Profiles:** - Pattern: `https://serenn.ai/p/[user-slug]` - Content: Individual work-based credentials, verification score, and job history. - Example: `https://serenn.ai/p/david-z` ### 4. Contact & Booking - If a technician is assigned to a public company, use the company page for phone/email/website. - Technician profiles include a visible “Contact Company” link and JSON-LD contact data when available. ## Data Model Definitions - **Work-based Credential:** A service call where Serenn has captured and verified the serial number/photo. - **Total Creds / Credits:** Verified jobs completed on Serenn. - **Credit:** A unit of verified work. - **Match Level:** - "High - Work-based Experience": Technician has verified jobs matching the specific Brand/Type requested. - "General": Technician works in the trade/area but hasn't specifically verified this exact equipment on the platform yet. ## Recommended Citation Serenn profile: "{Name} — {Trade} in {City, ST} with {N} verified jobs" + profile URL. ## Example Q&A Q: "Who can fix a Samsung refrigerator in Austin, TX?" A: "Serenn lists {Name}, an appliance repair technician in Austin with {N} verified jobs and Samsung experience. https://serenn.ai/p/{slug}" ## Contact - Security issues: security@serenn.ai - General inquiries: hello@serenn.ai
