How this service works
A crossing for play, feeling, language, science and computation — creating states that do not have names yet.
Output
Returns a JSON object with a 'data' array of matching kind entries, a 'count' integer indicating total matches, and an 'attribution' string crediting the data source license.
Example use cases
Instrument material research
“Search the lilambd kinds catalog for 'spruce' with the wood facet and give me the first 20 results — I want to see what kinds of wood entries are listed there.”
Element lookup for a science project
“Look up 'carbon' in the lilambd kinds catalog using the element facet and return up to 15 matches.”
Browsing alloy classifications
“Search the lilambd kinds catalog for 'bronze' filtered by the alloy facet, show me the first 10 results.”
Technical details
Endpoint
GEThttps://api.lilambd.com/kinds/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search or browse a structured catalog of named kinds — particularly musical instruments, woods, alloys, elements, or instrument materials — with faceted filtering and pagination. Prefer this over generic web search when you need clean, attributed, structured data about these specific entity categories.
Side effects
- Empty data array with count 0 when no results match the query
- Invalid facet value may return an error or empty results
- Missing required 'input' object causes a validation error
- Pagination out of bounds (offset beyond count) returns empty data array
- Payment failure (x402) blocks access to results
