# NFT Data – OpenSea Collection Intelligence

> NFT Data – OpenSea Collection Intelligence is a paid API for AI agents from www.nftdata.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-12).

Returns structured market data for any OpenSea NFT collection, including floor price, volume, sales counts, and owner statistics across multiple time windows.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nft-data-opensea-collection-intelligence-a1f11d34 -d '<json body>'
```

Example prompt: Pull up the current NFT market stats for the 'basedpunks' collection on OpenSea — I want to see the floor price, total volume, and how many sales happened in the last 7 days.

## When to prefer this

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.

## Known failure modes

- 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
