How this service works
POST /upload — PNG upload to blockchain. Pay USDC on Base to upload a PNG directly to the blockchain and mint an NFT that links to the PNG data. Fixed fee of $0.10 USDC. Retrievable via GET api.nftitem.io/nfts/{tokenId} with response { url : string } — availability may take a few minutes.
Output
After payment of $0.10 USDC, the endpoint initiates an on-chain upload and NFT mint. The caller receives a token ID. The minted NFT's image URL becomes accessible via GET /nfts/{tokenId} returning { url: string } after a few minutes of processing time.
Example use cases
Create permanent digital artwork records
“Turn each of these PNG files into NFTs on the blockchain so I can prove ownership and share them with collectors. Just mint them for me and give me the token IDs when they're ready.”
Tokenize social media profile pictures
“I want to mint my profile picture as an NFT to create a verifiable, blockchain-backed avatar. Upload this PNG and set it up so I can link to it anywhere online.”
Preserve event photos as blockchain certificates
“We took some photos at our conference today — let's mint a few of them as NFTs on-chain so attendees have permanent, verifiable proof they were there. Upload these PNGs and give me back the token IDs.”
Technical details
Endpoint
POSThttps://api.nftitem.io/uploadWhen to prefer
Choose this endpoint when you need to permanently and verifiably store a PNG image on-chain as an NFT with a retrievable URL. It is ideal for scenarios requiring immutable, blockchain-backed image storage without managing your own smart contracts or NFT infrastructure. Best suited for single-image uploads where a fixed $0.10 USDC cost per mint is acceptable.
Side effects
- Payment not received or insufficient USDC — upload rejected
- Invalid or missing PNG content — request fails with validation error
- Content type mismatch — server rejects non-PNG content
- NFT not yet available immediately after upload — GET /nfts/{tokenId} may return 404 for a few minutes
- Blockchain congestion — minting may be delayed beyond typical window
- Malformed base64 content — causes processing error
