Card declines from Latin American banks are usually the payment processor's risk control flagging the card's region or issuing bank — not a problem with your balance. This happens even when the bank confirms nothing was blocked on their end. Support tickets on this can take days since it requires the processor, not OpenRouter, to review.
If you've already opened a support ticket, that's the right first step — regional flags sometimes get manually cleared. While you wait, a crypto top-up bypasses the card processor entirely.
ROZO Checkout takes USDT, USDC, BTC Lightning, and other coins directly against an OpenRouter payment link, landing in roughly 30–90 seconds, for a 1% fee. It doesn't resolve the card decline itself, just gives you a way to pay without it. ROZO is independent, not affiliated with OpenRouter or Coinbase.
