# Proof of Use

> A source-reviewed editorial collection of 12 open-source AI projects. No projects were installed, executed or benchmarked for this edition. Sources checked 2026-10-14.

## Structured data
- /catalogue.json: complete catalogue, metadata, evidence definitions and 12 records (schema 1.0.0)
- /tools.json: flat array of the same 12 records
- /data/{id}.json: one record

## PDF tool selection (free prototype)
- /tool-match/: human report form; no PDF uploads or charges
- /tool-match/demo/: click-to-run documentation-based matching examples; no extraction
- /tool-match/evidence/: measured pdfplumber outputs on five synthetic PDFs, raw failures and reproduction files; not a broad accuracy estimate
- /tool-match/request.schema.json: seven-field request contract
- /tool-match/response.schema.json: result and error contract
- /tool-match/example-request.json: example request
- /tool-match/dataset.json: five tools with source-backed constraints
- /tool-match/API.md: full agent guide
- /tool-match/MCP.md: MCP connection guide
- /tool-match/examples/README.md: reproducible requests and expected results
- POST /api/v1/mcp: read-only Streamable HTTP MCP tool endpoint
- GET /api/v1/status: verify deployment and no-payment state
- GET /api/v1/quote: current $0, proposed future $1
- POST /api/v1/pdf-tool-match: deterministic rules; maximum 4096 bytes JSON
The API uses this site's configured access level. No API key is created by this prototype. Status is matched or abstained; never pad the list. Model licenses and code licenses are separate.

## Human-readable pages

The discovery pages contain static server-readable HTML. The PDF matcher form runs browser-local rules; equivalent structured reports are available through the deployed Worker API. Use cases are documented possibilities, not independently tested outcomes. Code licensing is separate from weights, data, outputs and provider terms. Verify current primary sources before acting. No purchases, account setup or external actions are supported by this site.
