Authentication
Send your key the way your client already does.
Simpang keys start with sk-sp-. Any one of these works:
| Header or param | Used by |
|---|---|
Authorization: Bearer sk-sp-... | OpenAI clients, curl, Claude Code with ANTHROPIC_AUTH_TOKEN |
x-api-key: sk-sp-... | Anthropic SDK, Claude Code with ANTHROPIC_API_KEY |
x-goog-api-key: sk-sp-... | Gemini clients |
?key=sk-sp-... | Gemini REST |
Keep keys safe
- A key is shown once. Simpang only stores a hash of it.
- Use one key per tool or machine, so you can revoke one without breaking the rest.
- Revoking or disabling a key blocks it within a second.
- A key can expire, carry its own monthly limit, and be limited to some models.
