How billing works. The rate above is what usage costs against your prepaid credits on a paid plan — no per-token markup, and Zylo's flat 25% platform fee applies only when you add credits. The free Basic plan instead gives a daily allowance of Basic-tier models (10 requests/min, no card, no credits). GLM 5 is a Basic-tier model — callable on the free Basic plan within its daily allowance and a global 10 requests/min limit. Prices update live from our catalogue.
