  description: 'Deterministic PDF rendering API: GitHub-flavoured Markdown or a compact DSL to tagged, PDF/A-2A + PDF/UA-1 dual-compliant PDFs. Authenticate with a Bearer token (API key or OAuth device flow), or pay per call via x402 (USDC on Base) on the x402-tagged operations. Errors use the shared Error schema. Rate limits are reported in RateLimit / RateLimit-Policy headers, with Retry-After on 429. Versioning: the major version is in the path (/api/v1); breaking changes ship as a new version, and a deprecated endpoint keeps working for at least 90 days after it starts sending Deprecation and Sunset headers.'
  x-guidance: 'POST /api/v1/markdown converts markdown to PDF ($0.01). POST /api/v1/render renders a template from templateId or inline DSL ($0.02). Both require an x402 payment: call unpaid to receive the 402 challenge (PAYMENT-REQUIRED header), sign an EIP-3009 USDC transfer, retry with the PAYMENT-SIGNATURE header. Free: GET /api/v1/templates?owner=library lists curated templates.'
