How this service works
Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.
Output
Returns a JSON object indicating whether the API key is valid, the list of granted scopes (e.g. 'internal', 'autonomous_loop', 'bypass_x402'), where the key originates from (e.g. 'env'), the key type, the timestamp of the check, expiry timestamp (or null if non-expiring), key prefix (or null), and rate limit per minute (or null).
Example use cases
Pre-flight agent loop validation
“Before kicking off my autonomous agent loop on three.ws, check that my API key is valid and has the autonomous_loop scope — I don't want it to fail mid-run.”
Debugging a 402 payment bypass issue
“My three.ws agent keeps hitting payment walls even though I should have bypass_x402 access — can you check my API key to see if that scope is actually granted?”
Internal key audit for a deployment
“I'm deploying a new three.ws 3D agent and I need to confirm the API key we're using is an internal key, is still active, and isn't rate-limited. Can you run a health check on it?”
Technical details
Endpoint
POSThttps://three.ws/api/x402/api-key-health?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that a three.ws API key is active and carries the correct scopes before executing an agent workflow or embedding a 3D agent. Prefer it over manual inspection or assuming key validity, especially in autonomous agent loops where a stale or insufficient key would cause mid-run failures.
Side effects
- Invalid or missing API key returns valid:false
- Requested scope not present in granted scopes list
- Key expired — expires_at in the past
- Network or server error returns HTTP 5xx
- Malformed request body returns HTTP 400
- Payment not provided for $0.001 USDC x402 endpoint returns HTTP 402
