Synchronous HTML to A4 PDF, 0.020 USDC with seven-day deletion eligibility, not

Synchronous HTML to A4 PDF, 0.020 USDC with seven-day deletion eligibility, not a hard public-access cutoff; asynchronous cleanup and caches may persist. Not renewable. Non-guessable public URL, not private: do not submit sensitive content. HTTP x402 only; no PDF MCP tool or MPP route. Candidate implementation; deployment not verified.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
