Authentication

All API requests require a Bearer token in the Authorization header.

Base URL

https://api.loomal.ai

Authentication

Include your API key in every request:

curl https://api.loomal.ai/v0/payments \
  -H "Authorization: Bearer loid-your-api-key"

API Key Types

Loomal has two key types. They are deliberately non-overlapping — use the right one for the job.

A loid- key cannot manage other projects. A lopk- key cannot act as any project. If you need both capabilities, use both keys.

Both formats are {prefix}-{64 hex characters}. Keys are shown only once at creation — store them securely.

Rate limit headers are included in responses:

• X-RateLimit-Remaining

Platform Keys

Platform keys (lopk-) are created in the console under your organization settings and unlock the /v0/platform endpoints for creating, rotating, and revoking projects programmatically.
