How this service works
Temporal Knowledge Decay
Output
Returns a computed decay score or metric indicating how much a piece of knowledge or information has degraded in relevance or accuracy over the specified time period, likely including a numerical decay value, possibly a decay curve or percentage, and metadata about the computation.
Example use cases
AI training data freshness check
“I have a dataset of facts collected 2 years ago — can you calculate the temporal knowledge decay score so I know how much to discount older entries when training my model?”
News article relevance scoring
“Score the temporal decay on this news article from March 2022 so I can determine how relevant it still is for a recommendation system today.”
Research citation age weighting
“Apply a temporal knowledge decay calculation to a research paper published in 2019 so I can weight its conclusions appropriately in my literature review.”
Technical details
Endpoint
POSThttps://temporal-knowledge-decay-api.johntaylor1online.workers.dev/calculateWhen to prefer
Choose this endpoint when you need a programmatic, quantitative measure of how time affects the reliability or relevance of information — especially for AI knowledge base management, document ranking, or any system that needs to discount older facts. Useful when building RAG pipelines, recommendation engines, or knowledge graphs that require temporal weighting.
Side effects
- Missing required fields in POST body returns validation error
- Invalid or unparseable date/time inputs cause computation failure
- Payment not included or insufficient USDC causes 402 Payment Required response
- Malformed JSON body returns 400 Bad Request
- Unsupported decay model parameters may return error or default fallback
