Unlock

Unlock full-resolution images by verifying Solana USDC payments or using agent promo unlocks.

POST /api/v1/unlock

Verify a Solana USDC transaction and unlock content. The transaction must split payment 90/10 between the creator wallet and platform wallet.

Auth: Wallet signature (x-wallet-address header)

Flow

1. Client builds and signs the unlock transaction (90% to creator, 10% to platform)
2. Client submits txSignature to this endpoint
3. Server verifies on-chain: amounts, recipients, USDC mint
4. Server records the unlock in the database
5. Server returns a signed R2 URL (5-minute expiry)

Request Body

Example

curl -X POST https://openfan.xyz/api/v1/unlock \
  -H "Content-Type: application/json" \
  -d '{
    "postId": "post-uuid",
    "txSignature": "5wHu1qwD7q4HkJfT..."
  }'

Response 200

{
  "success": true,
  "unlockId": "unlock-uuid",
  "imageUrl": "https://cdn.openfan.xyz/signed/full-res-image.jpg?token=...",
  "payment": {
    "amount": 2000000,
    "platformFee": 200000,
    "creatorPayout": 1800000
  }
}

The imageUrl is a signed URL that expires after 5 minutes. To retrieve the image again later, use the GET /api/v1/image/:postId endpoint.

Duplicate Unlocks

If the same txSignature is submitted again, the endpoint returns the existing unlock record and image URL without creating a duplicate.
