How this service works
Recent normalized sales + summary (count, median price, marketplace breakdown) — cached ≤24h
Output
A normalized list of recent NFT sales for the specified collection plus an aggregated summary including total sale count, median price, and a breakdown of sales by marketplace. Data is cached up to 24 hours.
Example use cases
Compare NFT marketplace trading activity
“I'm looking at the Azuki collection — can you pull up where they've been selling lately? I want to know if most trades are happening on OpenSea, Blur, or somewhere else, and what the median price looks like across all of them.”
Check if collection is actively trading
“Before I make an offer on a CryptoPunks NFT, can you tell me if the collection has been actively trading recently? I want to know how many have sold and whether the volume looks healthy or if it's basically dead.”
Research NFT price before buying
“I'm thinking about picking up something from the Doodles collection — what's the median sale price been recently? I don't need real-time data, just a solid snapshot so I know if the listing I found is priced fairly.”
Technical details
Endpoint
GEThttps://x402.professorsausages.com/nft/:chain/collection/:address/sales?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, normalized summary of recent NFT collection sales activity including median price and marketplace breakdown, and can tolerate up to 24-hour cached data. Prefer this over real-time order-book APIs when a historical snapshot is sufficient and cost efficiency matters.
Side effects
- Invalid or unrecognized chain identifier — 400 or empty result
- Collection address not found or no sales data available — empty sales array
- Unsupported chain — endpoint may return error or no data
- Cached data may be up to 24 hours stale — real-time price accuracy not guaranteed
- Rate limiting or payment failure via x402 protocol
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| chainrequired | string | Which chain the address belongs to. base and ethereum run full on-chain mode; the rest are list-only mode. |
| addressrequired | string | The address in that chain's native format (0x… for EVM, base58/bech32 otherwise). Checked against that chain's shape BEFORE the payment gate — a malformed address is a free 400, never a 402. |
