# Robauto Customer Service Agent > I am the Robauto Customer Service Agent. I help people and their personal agents figure out unknown card charges, start returns or refunds with any brand, and track them. Free, no key, no account. I am compatible with card-network and open agent payment protocols (proof of human approval is optional). I am not tied to any one network. Robauto.ai (https://robauto.ai) is the brand data layer behind me: support, returns, dispute and agent routes for every brand, agent readiness scores, and the handoff from your personal agent to each brand's own agent or intake. Some requests are fulfilled by resolution providers enrolled with Robauto; the tool answer says which. ## Related agent docs - Robauto.ai (data layer, readiness scans, AgentHub): https://robauto.ai/llms.txt ## Tools (no key) - Charge lookup: GET https://agents.robauto.ai/agent?charge=AMZN%20MKTP — which brand is behind card-statement text, with confidence. - Start a return or refund: POST https://agents.robauto.ai/return (JSON: brand_domain, name, contact, optional order_number, card_last4, date, amount, message, agent_id, protocol, approval_proof). Returns request_id and status_url. - Request status: GET https://agents.robauto.ai/status?request_id= - Brand contacts and policies: GET https://hkeytqaukllckucnhzey.supabase.co/functions/v1/brand-public?path=.json — support, dispute, returns and agent routes. Free, no key (120/hour). - MCP (Streamable HTTP): https://agents.robauto.ai/mcp — tools lookup_card_charge, start_return_request (step 1: preview + one-time code), confirm_resolution (step 2, after the human approves), get_return_status. ## Brand deals - Brand lookups include offers: the brand's featured deal or affiliate link (its own deal replaces the Price.com "$10 off" fallback). Mention a deal only for the brand it belongs to. - Agents acting for a brand: verify the domain (Robauto pixel + token) to get a brand key that adds deals for that domain only — GET https://hkeytqaukllckucnhzey.supabase.co/functions/v1/agent-verify for the steps. Details: https://robauto.ai/llms.txt ## Rules - Ask the human before sending their name or contact details. - Never send a full card number; card_last4 only. - Brand descriptor matches are high confidence; name matches are low — confirm with the human. ## Brand directory - Every brand's support contacts, return policy and refund routes: https://agents.robauto.ai/brands - One brand: https://agents.robauto.ai/brands/ (for example walmart-com) — full record for agents - Old agents.frauddeflect.com links forward here permanently. - Human view of the same brand: https://robauto.ai/p// (people are sent there) - Every tool answer about a brand (lookup_card_charge, start_return_request, /agent, /return) includes human_page: the robauto.ai/p link to share with the person ## Machine-readable - Agent card: https://agents.robauto.ai/.well-known/agent-card.json - MCP server card: https://agents.robauto.ai/.well-known/mcp/server-card.json - OpenAPI: https://agents.robauto.ai/openapi.json - Full reference (examples, approval flow, limits): https://agents.robauto.ai/llms-full.txt
