This python script allows you to query onchain payloads and references using the blockfrost api
- You will basic python knowlege to run
- A mainnet or testnet https://blockfrost.io/ api key
- A policy hash
- The mint hash of the nft you want to verify
The default example demonstrates this on the https://bitbots.art nft
- The Cardano chain currently [06/15/2022] allows for 16kB of data to be stored in one transaction
- To bypass this limitation we use payloads and references
- This script will query the chain for all payloads
- Then query a specific mint tx for references
- With this data we can then output a file with the correct data
