Add credit.
Verifying stays free. Credit is for issuing. Four ways to pay, cheapest first.
cheaper first
- x402
An agent tops up on the x402 rail without this page. See payments and the MCP server.
- USDC
Settle direct. Write to billing@scytalex.com from the account address.
- invoice
Card or ACH on a Scytalex invoice. Request one.
card
Sign in on the account console and pay a catalog pack by card. Amounts come from the server catalog, not this page. Entitlement lands when the webhook grants — a charge is not a credit until then.
