Rename referral code
The response body shown here is a static example, not live data. After you click Send, your live result appears in a separate panel headed 200 OK. The panel under the status-code tabs is a fixed sample from the spec — its field values (fees, prices, sizes, IDs, timestamps) are placeholders. Use Send, or call the endpoint, for current values.
Renames the authenticated affiliate’s referral code to a new string in place. Existing referees keep earning the affiliate commission (the referrer↔referee link is by account, not by the code string), and the code’s kickback is preserved. The old string is retired permanently — it can never be re-created or reclaimed by anyone, so links already shared under it stop resolving rather than later pointing at a different affiliate. Requires the affiliate to already hold a code (use createCode otherwise). The new string must be free: not currently owned and not a previously-retired (tombstoned) string.

Authorizations

X-API-Key
string
header
required

Hex-encoded Ed25519 public key (64 chars). The public key IS the API key — register it via POST /createApiKey. Required on every authenticated request, both read-only and signed.

X-Timestamp
string
header
required

Unix time in nanoseconds as a decimal string (e.g. "1713825891591000000"). Millisecond or second epochs are rejected with 401 Unauthorized. Must be within ±30,000 ms of server wall-clock, or the request is rejected with 401 Unauthorized. Required on all mutating / credential-creating endpoints. This same value must appear as the ct field in the ordersign typed canonical payload (single-order endpoints) or in each element's ct field (batch endpoints).

X-Signature
string
header
required

Lowercase hex-encoded Ed25519 signature (128 chars).

Single-order endpoints (placeOrder, cancelOrder, modifyOrder, and other non-batch mutating routes) sign over the ordersign typed canonical payload — a compact, key-sorted JSON object built from parsed request fields using engine-native integer values:

ct must equal the X-Timestamp header value. Keys in brackets are conditional (omitted when empty). op values: 1=place, 2=cancel, 3=modify. See the ordersign package for field definitions and reference signing code.

Other signed routes (e.g. createApiKey) still use the legacy scheme: signing_message = X-Timestamp + ACTION + canonicalJSON(body), where ACTION is the camelCase final path segment.

Batch endpoints (batchPlaceOrders, batchCancelOrders, batchModifyOrders) do NOT use this header. They authenticate with per-element typed ordersign signatures embedded in the request body (see the global auth description and the per-field signature descriptions on OrderRequest / CancelOrderRequest / ModifyOrderRequest).

Read endpoints are authenticated by ?address= (and optionally X-API-Key) only — no signature is required, except for the signed affiliate reads (see the Referral tag), which require the full header triple; with no body their signing message is X-Timestamp + ACTION. canonicalJSON(body) is the JSON body with object keys sorted lexicographically at every level and no whitespace; the server canonicalizes the received body before verifying, so only the bytes signed over must be canonical. Required on all mutating / credential-creating endpoints.
