https://animica.dev/x402/tx/preflightPOST /x402/tx/preflight · x402 API by animica
Find out why an Animica transaction would be rejected BEFORE you broadcast it. Decodes your canonical CBOR {body, sigs} envelope, returns the normalised fields and the CANONICAL HASH you are about to sign, then asks the node whether it would admit the transaction and why not. Both calls are read-only: nothing is inserted into the mempool and nothing is broadcast. Built for people writing Animica signers, where the alternative feedback loop is broadcast-and-see. No model.
