Numerics Interpolation

by Exact Interpolation Receipt in AI models & inference

x402 APIPassing, checked 43 min ago

Interpolate between two integer-coordinate points with exact rational arithmetic and an integrity receipt. Refuses extrapolation and repeated nodes. Does not estimate measurement error or validate the interpolation model. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.011501.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://www.mahastrategies.com/api/v1/compute/numerics/interpolation' \
  -H 'content-type: application/json' \
  --data-raw '{"dataClass":"synthetic","x":"1","x0":"0","x1":"4","xUnit":"s","y0":"0","y1":"10","yUnit":"m"}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
