Quickstart

From key to first request in under a minute. If your tool speaks the OpenAI or Anthropic API, it works here — just change the base URL.

1. Get your key

  1. Sign up with your email (magic-link, no password).
  2. Top up your USD balance with crypto.
  3. Your API key appears in the dashboard after the first top-up — copy it right away, it is shown once.

2. Make a request

base_urlhttps://api.cheaptokens.dev/v1
curl
curl https://api.cheaptokens.dev/v1/chat/completions \
  -H "Authorization: Bearer $CHEAPTOKENS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "zai-org/GLM-5.3-Flash",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

OpenAI-compatible clients use the /v1 suffix; Anthropic clients use the root URL.

Limits & errors

390K context. Errors follow the standard OpenAI/Anthropic JSON shape. A 402 means your balance is exhausted — top up to continue.
