Query Parameters

​
validators
string
required

Provide a comma separated list of validator indices or pubkeys 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"
