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 with ok:true, the skill's id/slug/name/category/description, an array of tool function definitions (type, function name, description), the skill's markdown content, and a calledAt timestamp. Costs $0.01 USDC per call via x402.
Example use cases
Dynamically load skill before agent invocation
“Hey, before my agent starts helping customers with payments, fetch the 'stripe-checkout' skill definition from three.ws so I can see what tools it exposes and make sure it has everything we need.”
Discover available 3D agent capabilities
“I'm building a customer support agent and want to see what skills are available — can you pull the definitions for 'ticket-resolver' and 'knowledge-base-search' from the marketplace so I know what we can wire up?”
Verify skill compatibility before embedding
“We're about to embed a 3D agent on our website, but I need to confirm the 'product-recommender' skill definition from three.ws actually includes the filtering tools we require for our catalog.”
Technical details
Endpoint
GEThttps://three.ws/api/x402/skill-callWhen to prefer
Use this endpoint when you need to dynamically load a named skill's tool definitions and content from the three.ws marketplace at runtime, especially when building or orchestrating 3D AI agents that need to discover available capabilities on demand. Prefer this over hardcoding skill specs, or when you need to pay-per-use rather than subscribing.
Side effects
- Invalid or unknown skill slug returns an error or empty result
- Missing required 'skill' query parameter causes a 400-level error
- x402 payment not provided or insufficient causes a 402 Payment Required response
- Network timeout if the marketplace backend is slow
- Skill may be deprecated or removed from catalog, returning not-found
