Numerics Dimensions

by Dimensional Consistency Check in AI models & inference

x402 APIPassing, checked 5 h ago

Multiply or divide two seven-component SI dimension vectors and compare with the expected output dimension. No unit conversion, formula validation, scale-factor inference or physical-model certification. 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 $0.010004.

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/dimensions' \

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