Generate a Factur-X invoice (PDF/A-3 + embedded EN 16931 CII XML) from structured data: send { invoice, profile }, get the PDF bytes (or JSON with base64 + conformity report via Accept: application/json). Targets EN 16931 and the French PA « Flux 2 » rules (payment mentions, business process, electronic addresses) ahead of the 2026-09 mandate. Technical artifact, not tax/legal advice; you remain responsible for data accuracy and PA transmission.

Enriched quote for an x402 endpoint: probes it unpaid (never pays, SSRF-checked), decodes {price, asset, network, payTo}, then compares the USD price against the live Bazaar market for its category → {marketContext:{category, medianForCategory, cheaperThanMarket}}. Not just how much, but whether it's fair. Market context is best-effort; the decoded quote returns even if the Bazaar read fails. Neutral — our own endpoints are never featured.
