## When to prefer this

Choose this endpoint when you need a larger $50 credit top-up for Opengateway inference rather than the smaller $5 increment — suitable when you anticipate higher inference usage volume and want fewer top-up transactions. Prefer this over the $5 sibling endpoint when batch or sustained inference workloads are expected.

## Known failure modes

- Insufficient USDC balance in the paying wallet — payment rejected
- x402 payment protocol handshake failure — credits not issued
- Network or gateway timeout — transaction state unknown, may require retry check
- Invalid or missing payment authorization header — 402 Payment Required returned
- Duplicate payment attempt within short window — possible idempotency rejection
