Path Parameters

​
indexOrPubkey
string
required

Comma-separated validator indices and/or public keys (maximum 100 items by default). Comma-separated list (no spaces) of validator identifiers. Each identifier must be either:

  • A validator index as a base-10 integer (for example, 652648)
  • A BLS public key as a 96-hex-character string with or without the 0x prefix (case-insensitive)

Resolution and limits:

  • The server resolves public keys to validator indices before querying data.
  • The total number of identifiers must not exceed the server-enforced limit (default 100).
  • Identifiers that cannot be parsed or resolved result in HTTP 400.
Example:

"1,2,3"

Response

Matching validators were retrieved successfully. The data field contains either a single validator object (when one identifier is provided/resolved) or an array of validator objects (when multiple identifiers are provided/resolved).

Standard success envelope used by all API endpoints.

​
status
enum<string>

HTTP-independent status of the API operation. For successful responses this is always "OK".

Available options:
OK
​
