  "markdown": "# Nitrograph Claude Code Plugins\n\nOfficial Claude Code marketplace for [Nitrograph](https://nitrograph.com).\n\nNitrograph is the discovery layer agents call before they spend money on a service. It finds agent-usable APIs across x402, MPP, and other payment rails, ranks them by task fit and operational signals, and returns the service details needed to call the selected provider safely.\n\n## Plugins\n\n| Plugin | Description |\n|--------|-------------|\n| `nitrograph` | Discover, inspect, and call agent-usable APIs via Nitrograph. Adds the hosted Nitrograph workflow as MCP tools, the `nitrograph` skill, and a `/discover` command. |\n| `nitrograph-research` | Validated, pay-per-result research and enrichment (also listed in this marketplace). |\n\n### Tools\n\n| Tool | Purpose |\n|------|---------|\n| `nitrograph_discover` | Search and rank services for a task (`limit`, `offset`, optional `filters`) |\n| `nitrograph_service_detail` | Full call card for one service |\n| `nitrograph_invoke_service` | Call the service through Nitrograph, outcome recorded automatically |\n| `nitrograph_authenticate` | Verify a key, or start device pairing so the agent mints its own spend-capped key |\n| `nitrograph_report_outcome` | Record success/failure of a direct call |\n| `nitrograph_report_pattern` | Record a reusable workflow |\n| `nitrograph_session_status` | Check remaining quota without consuming any |\n\n## Install\n\n```text\n/plugin marketplace add nitrographtech/claude-plugins\n/plugin install nitrograph@nitrograph\n```\n\nRestart Claude Code after installation so the MCP tools, skill, and slash command are loaded.\n\n## Authenticate (for paid calls)\n\nDiscovery is free and needs no account. To let the agent **invoke** paid\nservices, connect once - no key to paste:\n\n- **OAuth (recommended):** `claude mcp add --transport http nitrograph https://api.nitrograph.com/mcp`, then `/mcp` → **Authenticate**. One consent sets spend caps ($1/call, $20/day, $200/month by default); the host holds tokens, you never see a secret. Your first **certified** call is free (a one-time $1 certified-only credit is seeded on connect).\n- **In-chat pairing:** ask the agent to authenticate - it calls `nitrograph_authenticate`, hands you a short code for [nitrograph.com/pair](https://nitrograph.com/pair), and receives its own spend-capped key after your one-time approval.\n- **Manual key (scripts/CI):** create a key at [nitrograph.com/dashboard](https://nitrograph.com/dashboard) and set `NITROGRAPH_API_KEY`.\n\nEvery paid call is quoted, validated, refunded on failure, and receipted.\n\n## Try It\n\n```text\n/discover lead generation\n```\n\n```text\nUse Nitrograph to find a web search API, then call the top result.\n```\n\n```text\nUse Nitrograph to find an image generation service under $0.05 per call.\n```\n\n```text\nUse Nitrograph to find a data enrichment API, inspect the top result, and show me the call card.\n```\n\n## Safety\n\n- Nitrograph processes the discovery queries, task context, outcome reports, and pattern reports that you or your agent send to Nitrograph.\n- Do not send secrets, private keys, bearer tokens, raw customer payloads, confidential customer data, or full downstream service responses in discovery queries or reports.\n- Always inspect service detail before invoking a paid service.\n- Treat `402 Payment Required` as a payment challenge, not as a failed service call.\n\n## Links\n\n- Website: <https://nitrograph.com>\n- Docs: <https://nitrograph.com/docs>\n- Privacy: <https://nitrograph.com/privacy>\n- Terms: <https://nitrograph.com/terms>\n- npm package: <https://www.npmjs.com/package/nitrograph>\n\n## License\n\nMIT\n",
