Photo To 3D Fast API — Pay Per Call with USDC on Base

Photo to 3D model (fast tier, 10-30s). Upload a single 2D image URL, get a textured low-poly GLB mesh with a preview thumbnail. Game-ready — drop straight into Three.js, Unity, or Godot. Part of the x402 Gateway — $0.15 per call, settled in USDC on Base. No accounts, no API keys: agents pay per request via the x402 protocol.

How payment works

Send a POST to https://x402.freeq.one/tools/photo_to_3d_fast without a payment header and the API replies 402 Payment Required with an x402 challenge (payTo address, USDC amount, Base network). A paying agent signs the USDC payment and retries with the PAYMENT-SIGNATURE header (base64 JSON payment payload) — settlement is verified on-chain in seconds and the API response returns with a PAYMENT-RESPONSE receipt header.

Example call

curl -X POST https://x402.freeq.one/tools/photo_to_3d_fast \
  -H "Content-Type: application/json" \
  -d '{"image_url":"https://x402.freeq.one/samples/toy.png"}'
