public/decode_action

Runs a hex-encoded Action.data payload through the exchange’s own ABI decoder and returns either the decoded fields or the exact reason the bytes were rejected, naming the 32-byte word and the field that broke. Reach for this first when a request fails signature verification (14014): every other route encodes Action.data server-side, so a client whose encoder emits a bad word never sees a decode error - the hashes simply disagree. This is the only route a client’s own bytes reach the decoder. Needs no auth and executes nothing.

Body

application/json

action_type

enum<string>

required

Which action layout the bytes are meant to be.

Available options:

order,

rfq_maker,

rfq_taker,

transfer,

external_transfer,

withdrawal,

liquidation,

set_session_key,

update_whitelisted_recipients,

delete_subaccount,

vault_deposit,

vault_withdraw,

vault_cancel,

vault_create,

vault_mint_shares,

vault_burn_shares,

vault_force_burn

encoded_data

string

required

ABI-encoded action data (the Action.data bytes), 0x-prefixed hex. Same value the *_debug routes return as encoded_data.

Response

Success

action_type

enum<string>

required

Echoed back so a batch of probes stays attributable.

Available options:

order,

rfq_maker,

rfq_taker,

transfer,

external_transfer,

withdrawal,

liquidation,

set_session_key,

update_whitelisted_recipients,

delete_subaccount,

vault_deposit,

vault_withdraw,

vault_cancel,

vault_create,

vault_mint_shares,

vault_burn_shares,

vault_force_burn

decoded

any

required

The decoded fields. Decimal values are at the protocol's 1e12 scale — the wire carries 1e18, and the codec rejects anything that does not convert exactly.
