How this service works
Machine-payable document & media generation via x402 (USDC on Base). Endpoints respond 402 with payment instructions; retry with an x402 payment header.
Output
Returns a binary PDF file (Content-Type: application/pdf) representing a formatted invoice document. The call first receives a 402 Payment Required response with x402 payment instructions; after submitting a valid USDC payment header on Base, the endpoint returns the generated PDF invoice ready for download or forwarding.
Example use cases
Example prompt
“Generate a PDF invoice for my client Acme Corp for 3 hours of consulting at $150/hour and a $50 software license fee, billed from my company Bright Labs LLC — I need it as a downloadable PDF.”
Technical details
Endpoint
POSThttps://docforge-selim.duckdns.org/invoice?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically generate a PDF invoice document and can settle payment via USDC on Base using the x402 micropayment protocol. Ideal for AI agents automating billing workflows where each invoice generation costs a flat $0.02 USDC. Prefer this over heavier SaaS invoicing APIs when you just need a one-shot PDF output without account setup or subscriptions.
Side effects
- 402 returned without payment header — expected; retry with x402 payment header
- Payment rejected due to insufficient USDC balance on Base
- Malformed invoice input data resulting in 400 Bad Request
- DuckDNS dynamic DNS resolution failure causing connection timeout
- Server unavailable or cold-start delay resulting in 503
- Invalid or expired payment token causing 401/402 re-prompt
