Skills

• Free Image Upload
  Upload an image (PNG, JPEG, GIF, WebP) up to 10MB and get a public CDN URL, with no auth and no payment. Images 1MB or under are PERMANENT (expiresAt: null); images 1-10MB are retained for 30 days. Send multipart form-data or JSON with base64.

• Permanent Image Upload
  Pay $0.01 USDC on Base or Solana via x402 to upload an image up to 10MB with permanent retention (no expiration). Two-phase flow: POST /api/upload/token (x402 payment) returns a token, then POST /api/upload with X-Upload-Token header uploads the file. Resulting upload response has expiresAt: null. Only needed for images over 1MB — under that, permanence is free. Permanence is backed by a 90-day on-site shutdown notice (terms section 2A).

• Permanent Image Upload (legacy $1 route)
  Legacy alias kept for backward compatibility. POST /api/upload/token/permanent charges $1.00 USDC for permanent hosting identical to what /api/upload/token now provides for $0.01. Prefer the $0.01 route; this exists so older integrations keep working.
