Conformance Scan Origin

by Mekler AI in Onchain & crypto

x402 APIPassing, checked 45 min ago

Diagnose x402 protocol and discovery configuration with separate linter and compliance grades. Optional quote_mode fast returns a payable first 402; resend the same input with proof, save the job/capability and poll. Default preserves compute-first admission. Base or Solana, 0.05 USDC per completed scan. Failed or expired unfinished work is uncharged; never replace a pending proof. Reports expire after 24 hours. Probes never pay targets or certify paid delivery.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.05.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://api.mekler.ai/v1/services/conformance/scan-origin' \

  --data-raw '{"origin":"https://api.mekler.ai","quote_mode":"fast"}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://api.mekler.ai/v1/services/conformance/scan-origin' \
