Prepaid gateway at provider list prices over 128 models, Claude, GPT, Gemini, DeepSeek and GLM among them, whose keyless sign-up funds an account with $0.05 and adds $1 once a person claims it by email — no card
The page this row is verified against names no free model, so the column stays empty; callable ids, where the row has them, are under Connect.
An account is one POST with no key, and the llms.txt says what it carries: “an agent-created account has $0.05; claiming adds an extra $1” — the claim is an email sign-in, the dollar “granted once per human”. The billing page narrows it: “Some models require a completed credit purchase and return 403 billing_required without one. Saving a card or having promotional credits does not satisfy that requirement.” Which models those are is not published. What the credit buys is list price — “Provider usage is billed at provider list prices with no usage markup” — GLM-5.3-Flash at $0.15 in and $0.50 out per million tokens, Claude Opus 5 at $5 and $25 — and a top-up starts at $5 plus a 5% platform fee.
