POST /v1/btc/tx-inspect
unprobed
Call before signing or broadcasting a Bitcoin transaction. Decodes a raw transaction hex or a PSBT and returns inputs, outputs, script types, addresses, vsize, fee rate when derivable, and objective signals such as RBF, dust outputs, non-standard sighash flags and unsigned inputs. Parses only the bytes you send: no network access. Describes the transaction; never advises whether to sign it.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
