Output
Returns a paginated list of NFTs owned by the specified Ronin wallet address, including token metadata such as token IDs, contract addresses, and associated NFT details, along with a pageKey for retrieving subsequent pages.
Example use cases
Axie Infinity NFT portfolio audit
“Look up all the NFTs held by Ronin address 0xDEADBEEF... — I want to see everything in that wallet, up to 100 items per page.”
Verify NFT ownership before trade
“Before I proceed with this trade, can you confirm whether Ronin address 0x12345... actually owns the NFT in question by listing all their NFTs?”
Monitor wallet NFT holdings
“Check what NFTs are currently in Ronin wallet 0xABCDEF... and give me the first 25 — I'll use the page key to get more if needed.”

Endpoint
POSThttps://synapse-api-brown.vercel.app/api/ronin/nft/by-ownerWhen to prefer
Choose this endpoint when you specifically need to enumerate NFTs on the Ronin blockchain (used by Axie Infinity and Sky Mavis games) for a given wallet address. It supports pagination via pageKey and limit, making it suitable for wallets with large NFT holdings. Prefer this over generic NFT APIs when Ronin-specific data is required and you are operating in a pay-per-call model via x402.
Side effects
- Invalid or malformed owner address returns an error or empty result
- Non-existent wallet address returns an empty NFT list
- Missing required 'owner' field causes a validation error
- Expired or invalid pageKey may return an error or reset pagination
- Rate limiting or payment failure results in 402 response
- Ronin network downtime or RPC issues cause timeout or 5xx errors
