- Stacks Node RPC API
- Stacker Set
Get stacker and signer set information
Retrieves stacker and signer set information for a given cycle.
GET
Parameters
Path Parameters
cycle_number
REQUIRED
integer reward cycle number
Query Parameters
tip
string Stacks chain tip to query from. Options:
- (empty/omitted): Use latest anchored tip (canonical confirmed state)
- `latest`: Use latest known tip including unconfirmed microblocks.
If no unconfirmed state is available, falls back to the confirmed canonical tip.
If the unconfirmed state check fails with an error, returns 404.
- `{block_id}`: Use specific block ID (64 lowercase hex characters)
**Note:** If `tip` is present but contains an invalid or malformed value
(i.e., not `latest` and not a valid 64-character hex block ID),
the node silently falls back to the latest anchored tip (same as omitting `tip`).
