How this service works
Compute absolute and percent change for $0.001 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns the absolute change (current minus reference value) and the percent change expressed as a decimal or percentage, indicating whether the movement was positive (increase) or negative (decrease).
Example use cases
Crypto price movement tracking
“Bitcoin was $58,000 yesterday and is $62,400 today — what's the absolute dollar change and percent increase?”
Portfolio performance calculation
“My stock position was worth $12,500 last month and is now worth $10,875 — calculate the absolute loss and percentage drop for me.”
Sales metric comparison
“Last quarter's revenue was $240,000 and this quarter it's $287,500 — what's the absolute change and what percentage did we grow?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/percent-changeWhen to prefer
Choose this endpoint when you need a reliable, pay-per-use microservice to compute percent and absolute change without building the math locally — particularly useful in agent pipelines where consistent, server-side arithmetic is preferred, or when chaining with other Delx data endpoints like crypto price feeds.
Side effects
- Missing or non-numeric input values returns a validation error
- Division by zero if the reference/previous value is zero
- Malformed request body returns a 400 error
- Payment failure or insufficient USDC balance prevents execution
