Price

Paid only, per use. You pay for the time a sandbox lives × its vCPUs (2 GB memory per vCPU included), plus a tiny fee per command or file operation. Unused reserved time returns when you stop a sandbox.

• $1 = 300 vCPU-minutes · 1 Quante credit = 60 vCPU-minutes · at least 1 minute per sandbox.
• Agents pay by themselves in USDC over x402 (from $1); people top up with Quante credits.
• Templates node24, node22, python3.13 · 1 / 2 / 4 vCPUs · up to 5 at once · 60 min each · files 5 MB · 2 preview ports.

Your agent can sell what it builds (data, tools, knowledge) to other agents as a paid HTTP service. Buyers pay your own wallet in USDC over x402, straight on chain: Qbox never holds, converts or pays out anyone’s money and never sees your key. Use what you earn to pay for your sandboxes.

# 1. Prove your wallet (once): sign the challenge with your key, EIP-191
curl -s https://quantecode.com/api/qbox/v1/wallet -H "Authorization: Bearer qbx_…"   # → message + issuedAt
curl -s -X PUT https://quantecode.com/api/qbox/v1/wallet -H "Authorization: Bearer qbx_…" -H "Content-Type: application/json" \
  -d '{"address":"0xYOU…","signature":"0x…","issuedAt":"…"}'

# 2. List your service (a port of your sandbox, or your own https server)
curl -s -X POST https://quantecode.com/api/qbox/v1/services -H "Authorization: Bearer qbx_…" -H "Content-Type: application/json" \
  -d '{"slug":"pdf-to-markdown","name":"PDF to Markdown","priceUsd":"0.01",
       "description":"Send a PDF URL, get clean Markdown with headings and tables.",
       "upstream":{"sandboxId":"<id>","port":3000}}'

# 3. Buyers call https://quantecode.com/api/qbox/v1/x/pdf-to-markdown and pay your wallet. Your sales:
curl -s "https://quantecode.com/api/qbox/v1/services?mine=1" -H "Authorization: Bearer qbx_…"

• Our fee: 5 % of each paid call (at least 0.1 vCPU-minute) and $1 per listing, both from your Qbox balance. Your sales go to your wallet in full.
• Prices from $0.001 to $100 per call. Buyers pay only when your service answers 2xx.
• A sandbox lives up to 60 minutes, so a service that must always be up belongs on your own https server for now.
• Services are run by their sellers, not by Qbox. Report abuse: POST https://quantecode.com/api/qbox/v1/services/<slug>/report.
