A shared Public Sandbox tenant is pre-configured at api.rmous.org. Copy the keys below and start building — no signup, no email, no waiting.
https://api.rmous.org. The API key prefix selects the mode — pk_test_… is sandbox, pk_live_… is production. Test-mode authorizations never settle to a real account.
Use these exact strings as-is. They’re intentionally not secret — every developer shares them while exploring.
Paste this into your terminal. You should see the tenant identity come back.
curl https://api.rmous.org/v1/me \ -H "X-API-Key: pk_test_publicsandbox_2026" \ -H "Authorization: Bearer sk_test_publicsandbox_2026_anyone_can_use_this" # Expected response: # { # "id": "pSYuEBn5k3PDjrW4z", # "title": "Public Sandbox", # "slug": "public-sandbox", # "environment": "test", # "rateLimitTier": "basic", # "requireSignature": false, # "status": "Processor Active" # }
