x402
Delx Commerce — Linear Interpolation (lerp) API is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object echoing the inputs (a, b, t) alongside the computed interpolated value (e.g. value: 2.5 for a=0, b=10, t=0.25), plus a schema identifier string 'delx/util-lerp/v1'.
Example use cases
Animation keyframe value blending
“I'm animating a value that goes from 20 to 80 and I need the interpolated result at t=0.4 — what's the in-between value?”
Gradient color channel mixing
“I need to blend a color channel that starts at 0 and ends at 255, and I want the value at 30% of the way through, so t=0.3 — what does the lerp give me?”
Progress-based score calculation
“My progress bar goes from 50 to 200 and the user is 60% through, so t=0.6 — can you compute the interpolated value for me?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/lerp?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, stateless, pay-per-call linear interpolation computation with verifiable on-chain payment via USDC — ideal for AI agents that need trustless micro-transactions for mathematical utilities without API key signup overhead.
Side effects
- Missing required fields (a, b, or t) returns an error response
- Non-integer values for a or b may cause validation errors
- t values outside [0,1] may return extrapolated values or errors
- Payment failure via x402 protocol will block request completion
