Deterministic edge engine performance benchmark — pay-per-call API

Name: code402 — Deterministic edge engine performance benchmark
Price: 0.000999 USD
Author: code402

$0.000999 per call · 20 free calls/day · no signup · pay with card credits or a signed USDC voucher (x402)

Real-time edge benchmark comparing deterministic sub-millisecond core vs pure JavaScript V8 for EIP-712/3009 cryptographic verification and zero-GC memory allocation.

Honest scope: Deterministic, offline, explainable — no ML, no scraping. The response's scope field states the exact guarantee.

Try it (first 20 calls/day free)

curl -X POST https://code402.dev/v1/tools/engine-benchmark/call \
  -H "content-type: application/json" \
  -d '{"iterations":500}'

No key needed for the free tier. When the free quota is used up, the API replies HTTP 402 with the exact price — agents sign the x402 voucher and retry; humans buy card credits. Every paid response carries a signed receipt you can verify offline.
