How this service works
Yearly RIS/HRI research-intensity history for one chemical element.
Output
A time-series array of yearly data points for the specified chemical element, each containing the year, RIS (Research Intensity Score), and HRI (Hyper Research Intensity) values, allowing trend analysis of how scientific research activity around that element has changed over time.
Example use cases
Tracking lithium research surge
“Show me the full yearly research intensity history for lithium (Li) — I want to see if the RIS and HRI scores spiked during the battery technology boom.”
Benchmarking rare earth element interest
“Can you fetch the annual RIS and HRI history for neodymium (Nd)? I'm trying to understand how research activity around rare earth elements has evolved.”
Comparing historical gold research trends
“Get me the year-by-year research intensity history for gold (Au) so I can see when scientific interest in it peaked and whether it's been growing recently.”
Technical details
Endpoint
GEThttps://www.elements-live.com/v1/elements/:symbol/history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the historical year-by-year research intensity trend for a specific chemical element (by symbol), and you want RIS/HRI metrics rather than raw paper counts. Prefer this over the topic-based history endpoint when your query is explicitly about a periodic-table element rather than a broader research topic or compound.
Side effects
- Invalid or unrecognized element symbol returns an error or empty result
- Element symbol provided in wrong case or format (e.g. full name instead of symbol) may fail
- Payment failure or insufficient USDC balance blocks the request under x402 protocol
- Rate limiting or quota exhaustion returns a 429 or payment-required error
- Network timeout if the data source is temporarily unavailable
