Best option from inside CN

If you're billing in CNY and don't want to wrestle Stripe, DMX is genuinely the smoothest option. Phone support has actually saved me twice. Latency to other regions is rough though.

Bill came in 12% above what the pricing page said

Self-audited a $40 spend. Sonnet input was $0.99/M not the advertised $0.90/M. Asked support — was told 'rate card moves with upstream demand'. Caveat emptor.
