SignalDesk AI Linear Interpolation
x402
SignalDesk AI Linear Interpolation is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-09).
Computes the linearly interpolated y-value for a given x between two known data points (x0,y0) and (x1,y1)

How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object containing the single numeric field 'y', which is the linearly interpolated value at the given x position between the two provided data points using the standard linear interpolation formula: y = y0 + (x - x0) * (y1 - y0) / (x1 - x0).
Example use cases
Animate value between keyframes
“I have a keyframe animation where at frame 0 the opacity is 0 and at frame 60 it is 255 — what is the opacity at frame 40?”
Estimate sensor reading at timestamp
“My sensor reads 30 degrees at time 100 and 80 degrees at time 200 — can you interpolate what the temperature would be at time 150?”
Scale score to new range
“I need to map a test score of 65 that sits between 50 and 100 on the old scale to a new scale that runs from 0 to 10 — what is the interpolated value?”

Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/math/linear-interpolate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap, stateless computation of a single linear interpolation without setting up local math libraries. At $0.001 USDC per call it is ideal for AI agents that need occasional on-demand interpolation in workflows where installing numeric libraries is impractical. Prefer this for real-time pipelines needing a reliable hosted math microservice.
Side effects
- x0 equals x1 causing division by zero (undefined behavior or error)
- Missing required fields x, x0, x1, y0, or y1 returns a validation error
- Values outside the allowed range [-1e15, 1e15] are rejected
- Non-numeric inputs cause schema validation failure
- Payment not included or insufficient USDC causes 402 Payment Required response
