Query Parameters

limit

integer

default:10

Maximum number of results (1-50)

Required range: 1 <= x <= 50

offset

integer

default:0

Number of results to skip for pagination

Required range: x >= 0

Body

application/json

Base filter request with range parameters. Validation rules: (1) Must provide either block range OR datetime range, not both and not neither. (2) When using block range, both from_block AND to_block are required. (3) When using datetime range, both from_datetime AND to_datetime are required. (4) to_block must be >= from_block. (5) to_datetime must be >= from_datetime. (6) Block range cannot exceed 100 blocks.

from_block

integer

Start block number. Required if using block range.

Required range: x >= 0

to_block

integer

End block number. Required if using block range. Must be >= from_block and within 100 blocks.

Required range: x >= 0

from_datetime

string<date-time>

Start datetime (ISO 8601, timezone required, e.g., 2024-01-15T10:30:00Z or 2024-01-15T10:30:00+00:00). Required if using datetime range.

to_datetime

string<date-time>

End datetime (ISO 8601, timezone required, e.g., 2024-01-15T10:30:00Z or 2024-01-15T10:30:00+00:00). Required if using datetime range. Must be >= from_datetime.
