API quick start

Make your first API call in a minute.

Use your ScaleMax key as a Bearer token with the OpenAI-compatible API. The request below uses the public fable-5 model ID, which requires a Claude-capable or both-scope key.

For a token-budget key, replace /v1 with /token/v1. The ScaleMax CLI and supported-client setup select the correct base URL for your key automatically.

Customer-facing USD per 1M tokens. Every provider-reported input token is charged at the published input rate; internal provider cache pricing does not reduce customer API-credit usage.

GLM 5.2 is sold as a prepaid token key: 100M tokens for $10. Configured long-context rates apply automatically when a model request crosses its published threshold.

Understand model IDsHow pricing is calculated

Prepaid credits

Pay about a tenth of the meter.

Every credit pack multiplies your internal usage-credit balance roughly 10×, and that balance spends at the listed customer model rates. Bigger packs include a larger promotional multiplier.

FAQ

Answers before you start.

Is ScaleMax a SaaS subscription?

No. ScaleMax is prepaid AI API access with model pricing, usage tracking, and OpenAI- and Claude-compatible gateway endpoints. You buy credit or a token allowance up front — there is no recurring subscription.

Do I need a new SDK?

No. Use OpenAI-compatible SDKs with the matching ScaleMax base URL, or use native Claude-compatible clients with a Claude-capable key. Chat Completions, Responses, and Anthropic Messages paths are documented separately.

Can I see my usage?

Yes. Check key status, expiry, credit balance, request counts, and token usage from your dashboard at any time.

What is the difference between credit and token keys?

A credit key draws down a USD balance against published model rates. A token key spends a fixed prepaid allowance for a model family. The base URL differs by billing mode and protocol, and the installer selects the matching route from the authenticated key.
