How this service works
Query any OpenSea NFT collection and get structured market data instantly. An ERC-8257 AI agent tool.
Output
A JSON object containing the collection's name, slug, contract addresses with chain info, floor price in ETH, total volume in ETH, total sales count, number of unique owners, total supply, creation date, and rolling sales/volume metrics for the past 1 day, 7 days, and 30 days.
Example use cases
NFT portfolio floor price alert
“Check the floor price and 24-hour sales volume for the 'azuki' OpenSea collection right now — I want to know if it's moved significantly today.”
Research NFT collection before buying
“I'm thinking about buying into the 'pudgypenguins' collection. Pull up their OpenSea stats — floor price, number of owners, total supply, and how much volume they've done in the last 30 days.”
Track NFT market activity for a report
“Get me the full market data for the 'boredapeyachtclub' collection on OpenSea, including total volume, total sales, 7-day and 30-day breakdowns, and how many unique owners there are.”

Endpoint
POSThttps://www.nftdata.app/api/get-collection-data?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, up-to-date NFT collection market data from OpenSea — particularly floor price, volume trends, and sales activity — without building a direct OpenSea API integration. Ideal for AI agents performing NFT market research, portfolio tracking, or investment analysis where a per-call micropayment model is preferable to managing API keys.
Side effects
- Invalid or non-existent collection slug returns an error or empty response
- Rate limiting or payment failure causes a 402 or 429 response
- OpenSea API downtime causes upstream data unavailability
- Collection has no recent trading activity, resulting in zero values for volume/sales metrics
- Misspelled slug returns no results
