How this service works
Linear interpolation between a and b by t. Call when you blend scores, progress, or animation parameters. Returns interpolated value for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns the interpolated numeric value computed as a + t*(b-a), representing the blended point between a and b at fraction t.
Example use cases
Blend two scores by progress
“I have a starting score of 50 and a target score of 300, and my player is 40% of the way through — what's the blended score at t=0.4?”
Animate parameter between keyframes
“I'm easing an animation from opacity 0 to opacity 255 and I need the value at 65% through the transition, so lerp between 0 and 255 at t=0.65.”
Calculate weighted mix of two metrics
“My baseline metric is 10 and my peak is 80 — what's the interpolated value when I'm 90% of the way there?”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/lerp?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, stateless, serverless linear interpolation computation without writing code — especially useful in agentic workflows where blending scores, progress bars, animation parameters, or any two numeric endpoints is needed on-the-fly at minimal cost ($0.001 USDC). It's ideal when you want a quick arithmetic result without spinning up a code interpreter.
Side effects
- Missing required parameters (a, b, or t) results in a 400 error
- t outside the 0–1 range may produce extrapolated values beyond a or b (not clamped by default)
- Non-numeric inputs for a, b, or t will cause a validation error
- Network or payment failure via x402 protocol may result in a 402 or 5xx response
