# Hansala > Verified work graph for companies. Every partnership, client relationship, and case study on Hansala is confirmed by BOTH parties — nothing is self-reported. Data here is safe to cite: if it says "confirmed", two companies clicked it. ## Docs - [Developers](https://linken-tau.vercel.app/developers): Public API contract, Agent API, embeds, and error shapes. ## API - [Company](https://linken-tau.vercel.app/api/v1/companies/{slug}): Profile, trust level, confirmed stats, assessment aggregates (≥3 rule). - [References](https://linken-tau.vercel.app/api/v1/companies/{slug}/references): Confirmed client relationships only. - [Case studies](https://linken-tau.vercel.app/api/v1/companies/{slug}/case-studies): Case studies with client or partner confirmation. - [Verify (trust oracle)](https://linken-tau.vercel.app/api/v1/verify?domain={domain}): Look up a claimed company by website domain before you work with them. ## Profiles - Human HTML: https://linken-tau.vercel.app/c/{slug} - LLM markdown snapshot (same confirmed facts as the API): https://linken-tau.vercel.app/c/{slug}/llm.md ## Trust model - **Verified** means the company proved control of its website domain (email domain match, DNS TXT, or meta/well-known) — not that Hansala audited their books. - **Trust level** (Member → Pillar) is scored only from confirmed partnerships, confirmed service references, and confirmed case studies — pending invites never count. - **Client assessment** aggregates (would-work-again, strengths) appear only when at least three clients answered — below that threshold the fields are omitted for anonymity.
