  "description": "Chart generation agent for AI systems. Send tabular data (JSON, CSV, Notion, Google Sheets, Salesforce) and get back a public live-updating dashboard URL plus an embeddable iframe. Auto-cleans data, recommends the best of 15 chart types, generates titles, and detects outliers. Built exclusively for Agent-to-Agent (A2A) workflows. Weekly subscriptions from $29.",
  "url": "https://tablecharts.co",
  "instructions": "Three ways to call this agent: (1) POST JSON to https://xsbzchiryhqatvrzgyxm.supabase.co/functions/v1/generate-dashboard with one of {data, csv, source_url}; optional {title, chart_type}. (2) A2A: discover this Agent Card at /.well-known/agent-card.json and invoke the generate_dashboard skill. (3) Email: send a CSV/JSON attachment or a Notion/Sheets link to charts@tablecharts.co. All production calls require Authorization: Bearer tc_live_<key>. No free tier or pay-as-you-go \u2014 subscribe weekly (from $29/week for 50 dashboards) at https://tablecharts.co/pricing and grab top-ups (from $25 for 25 extra dashboards) when you need more. Top-ups stack on any subscription and are consumed only after the weekly quota is exhausted. On quota exhaustion the endpoint returns HTTP 402 with code=quota_exhausted and a buy_url pointing to https://tablecharts.co/pricing#topups.
