  "markdown": "# supership\n\nThe search engine and clearing house for the agent economy. Built by [Crest Deployment Systems](https://crestsystems.ai).\n\nsupership indexes the entire x402 economy -- 52,000 services -- so an AI agent can **find** the right data and **fetch** it with a receipt. Reading the menu is free. Fetching through supership returns the goods plus a **signed delivery receipt**: proof of what you got, from where, settled on-chain. That is the part going direct can never give you.\n\n## Install\n\n```bash\nnpm install -g supership-scan\n```\n\n> Published on npm as `supership-scan` (the original name; kept for install continuity).\n\nRequires Node.js 18+.\n\n## MCP server\n\n```bash\nnpx -y -p supership-scan supership-mcp\n```\n\nOr wire it into any MCP client (Claude Code, Cursor, Windsurf):\n\n```json\n{\n  \"mcpServers\": {\n    \"supership\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"-p\", \"supership-scan\", \"supership-mcp\"]\n    }\n  }\n}\n```\n\n### Tools\n\n| Tool | What it does |\n|------|--------------|\n| `manifest` | Search the whole x402 economy (52,000 services) for what you need. Ranked by **distinct payers** -- real adoption, not call counts. Free. |\n| `procure` | Fetch any source. supership fronts payment across any chain, delivers the goods, and returns a **signed receipt**. No wallet needed on the seller's chain. First runs free. |\n| `list_catalog` | Browse a curated catalog of procurable sources. |\n| `scan_directory` | Scan a local directory for security issues before you ship. |\n\n## Free menu, paid kitchen\n\n- **The menu is free.** `manifest` shows the real market: every relevant source, free or paid, ranked by who actually paid for it. That ranking is the part you cannot compute yourself -- it takes the whole index and the payment history.\n- **The kitchen is the product.** When you `procure`, supership crosses to the source (on whatever chain it lives), pays, takes delivery, and hands you the goods **plus a signed delivery receipt** -- an Ed25519 record of what was delivered (source, SHA-256 of the goods, settlement tx, timestamp), verifiable at `/api/pubkey`. That receipt is the provenance going direct cannot give you.\n\n## HTTP API\n\n| Endpoint | Price | Description |\n|----------|-------|-------------|\n| `/manifest?need=` | Free | Search the economy; ranked by real payers |\n| `/catalog` | Free | Curated procurable sources |\n| `/sample?url=` | Free | Fetch one source on the house -- with a signed receipt |\n| `/procure?url=` | per-call | Fetch any source; goods + signed receipt |\n\nAPI base: `https://supership.crestsystems.ai`\n\nDiscovery: [agent.json](https://supership.crestsystems.ai/.well-known/agent.json) | [llms.txt](https://supership.crestsystems.ai/llms.txt) | [OpenAPI](https://supership.crestsystems.ai/openapi.json)\n\n## What supership does not do\n\n- It does not sell the data. It indexes the market and delivers what you ask for, with a receipt.\n- It does not hold your funds. The MCP server holds no keys and moves no money locally.\n- It does not give investment advice.\n\n## License\n\nApache 2.0.\n",
