{"name":"VendorStacks","tagline":"The subprocessor disclosure data API. Which vendors does a company run? VendorStacks reads what companies publish about themselves — subprocessor lists, DPAs and vendor disclosures — and returns a structured stack across 24 categories, each match carrying the quoted source as evidence. Because the source is disclosure rather than front-end fingerprinting, it sees back-end processors that never touch the browser. Built for GTM workflows and AI agents.","docs":"https://api.vendorstacks.com/llms.txt","openapi":"https://api.vendorstacks.com/openapi.json","agents":"https://api.vendorstacks.com/agents","skill":"https://api.vendorstacks.com/skill","pricing":"https://api.vendorstacks.com/pricing","pricing_json":"https://api.vendorstacks.com/v1/pricing","get_a_key":"POST https://api.vendorstacks.com/v1/keys {\"email\":\"you@company.com\"} → instant key + 25 free credits","try_it":"curl -H 'Authorization: Bearer <key>' 'https://api.vendorstacks.com/v1/check?url=posh.vip'","categories":["sms_messaging","email","payments","cloud_infra","analytics_data","support_cx","crm_sales","auth_identity","observability","productivity","ai_ml","privacy_compliance","hr_payroll","ecommerce_pos","database_infra","finance_accounting","esignature_contracts","integration_etl","search_discovery","media_cdn","realtime_infra","marketing_ads","security_fraud","data_enrichment"]}
