Run

cp .env.example .env
pnpm install
pnpm --filter @x402orcle/oracle-brain test
pnpm --filter @x402orcle/mcp test
pnpm --filter @x402orcle/mcp dev     # :4021
pnpm --filter @x402orcle/web dev     # :3000 landing

Unpaid consult → HTTP 402 + PAYMENT-REQUIRED (base64 JSON, extensions.bazaar).
Demo: POST /v1/demo/mint-payment then retry with PAYMENT-SIGNATURE.

Bazaar

Cataloging is settlement-triggered. Validate first (no pay):

curl -sS -X POST https://api.cdp.coinbase.com/platform/v2/x402/validate \
  -H 'content-type: application/json' \
  -d '{"resource":"https://YOUR_HOST/api/consult/oracle_ask","method":"POST"}'

Then one mainnet seed settle from a local burner. No settlement = no rank.
