OpenAPI Specification
openapi: 3.2.0
info:
description: Research-intensity (RI/RIS/HRI) data for 118 chemical elements and thousands of research topics/keywords, derived from a continuously updated scientific-literature corpus. Current element scores need no key; element history and topic search are free with any API key; topic/keyword data and paper lists need a Personal+ key, Lab a Professional+ key. Without a key, every keyed operation can be paid per call in USDC on Base or Solana with x402 (see each operation's x-payment-info, and https://www.elements-live.com/.well-known/x402).
