USDC on Base · near-zero gas

No signup. No API key.
Just pay and print.

Phantom Ink uses the x402 protocol — payment is baked into HTTP.

Your agent hits the endpoint, the server responds with a price, the agent signs a USDC transfer on Base, and the PDF arrives. One roundtrip. Works with any x402-compatible wallet — Coinbase AgentKit, WLFI AgentPay, or roll your own.

Human developers can pre-buy credit packs with a card. Agents pay per document without any account setup.

1
Agent sends request — POST HTML or template data to /api/v1/generate
2
Server responds 402 — includes USDC amount and Base address
3
Agent signs payment — USDC on Base L2. Fractions of a cent gas.
4
PDF delivered — binary stream or base64 JSON with metadata

Three lines to a document.

Basic renders your markup. Premium designs it for you.
