How this service works
Pay-per-call on-chain data API for AI agents: token prices, risk scoring, wallet intelligence, whale alerts, balances, tx history, cross-chain comparison — evidence-backed JSON, settled in USDC on Base via x402. No API keys, no signup.
Output
Returns a JSON object containing aggregated NFT data such as collection metadata, floor prices, sales volume, token-level ownership information, and on-chain statistics sourced across NFT marketplaces and the Base blockchain.
Example use cases
NFT collection floor price lookup
“What's the current floor price and 24-hour trading volume for the Azuki NFT collection on Base?”
Wallet NFT portfolio overview
“Show me all the NFTs held by wallet address 0xABC123... — collection names, token IDs, and estimated values.”
On-chain NFT ownership verification
“Can you verify who currently owns token ID 4521 from the CryptoPunks collection on-chain?”
