Overview
The node interacts with the PaintSwap NFT marketplace, providing various operations to retrieve and analyze NFT sales data. Specifically, the "Generate Price Heatmap" operation creates a heatmap representing price ranges within an NFT collection. This heatmap helps visualize how NFTs in a collection are distributed across different price brackets, which is useful for market analysis, pricing strategies, and identifying trends.
Practical examples:
- An NFT trader wants to understand the distribution of prices in a specific collection before making purchase decisions.
- A collector analyzes price clusters to identify undervalued NFTs within a collection.
- A developer integrates this node to generate visual insights on NFT marketplaces for a dashboard.
Properties
| Name | Meaning |
|---|---|
| Collection Address | Ethereum address of the NFT collection contract to analyze. |
| Step Percentage | The percentage increment used to define each price range step in the heatmap (e.g., 20%). |
Output
The output JSON contains the generated price heatmap data for the specified NFT collection. This typically includes price ranges segmented by the defined step percentage and the count or frequency of NFTs falling into each price range. The structure enables visualization of how many NFTs are priced within each bracket.
No binary data output is indicated for this operation.
Dependencies
- Requires access to the PaintSwap NFT marketplace API.
- Optionally requires an API key credential configured in n8n for authenticated requests (not mandatory).
- Needs network connectivity to query the PaintSwap service endpoints.
Troubleshooting
Common issues:
- Invalid or incorrectly formatted Ethereum collection address may cause errors or empty results.
- Network or API downtime can lead to request failures.
- Using a very small step percentage might produce too granular heatmaps, potentially impacting performance.
Error messages:
"The operation "generatePriceHeatmap" is not supported!"— indicates an unsupported operation was requested; ensure the correct operation name is selected.- Errors related to invalid addresses or API responses will be returned as error messages in the output JSON if "Continue On Fail" is enabled.
