Why this one
- Works with small models: complete error lists with actionable hints and a fill-in template — no trial-and-error loops burning your budget
- Results as HTTPS download links (XML + PDF, valid 24h) — no giant base64 blobs in your context
- Privacy by design: invoice data is deleted automatically after 24 hours. Nothing is stored permanently (GDPR-friendly)
- Honest math: send quantities, unit prices and tax rates — sums are computed and validated server-side, so the invoice always adds up
Pricing
10 free calls per month to test your integration. After that $0.05 per call. A typical invoice (template → create incl. PDF) takes 2–3 calls ≈ $0.10–0.15 per finished, validated invoice — no subscription, no base fee.
