find text from transaction message with blockfrost or koios

Question

small (maybe) easy question.

i want to find with blockfrost a "message" on a transaction.

can someone help me a bit for this? i dont find currently anything.

thank you in advanced. TTS17

By "message" on a transaction do you mean finding transaction metadata given a transaction hash? There is this Blockfrost resource or this Koios resource. — keefie, Commented Apr 23, 2022 at 6:49
i think we speak for the same. developers.cardano.org/docs/governance/… i think it is the ""Handling ill-formed 674 metadata"" thank i will do some test with real transactions and message. i want to ask people to text something specific and when i find transaction with this message, to do something else — TTS17, Commented Apr 23, 2022 at 14:36
perfect, i found one transaction with msg in cardanoscan and execute this command. ----- curl -H 'project_id: mainnetID' cardano-mainnet.blockfrost.io/api/v0/txs/… — TTS17, Commented Apr 23, 2022 at 14:45

Given the message in your context is the CIP 20: Transaction message/comment metadata, you can query this Blockfrost resource or this Koios resource to retrieve the metadata of a transaction given its hash, specifically retrieving the details under the 674 label.
