Combining Multiple Filters

Multiple filters can be applied in the same JSON object.

Example combining:

• transaction hash
• transaction type
• transaction date

Example JSON:

{ "transactionHash": { "operator": "contains", "value": "123456" }, "transactionType": { "operator": "contains_in", "value": ["trade","deposit"] }, "transactionDate": { "operator": "between", "value": { "startDate": "2026-03-01T00:00:00Z", "endDate": "2026-03-31T23:59:59Z" } } }

Encode this JSON to Base64 and pass it as:

GET /api/portfolio/{portfolioId}/transactions?filter=<BASE64>&page=1&pageSize=20

Encoding Filters

Browser

btoa(JSON.stringify(filter))

Node

Buffer.from(JSON.stringify(filter)).toString("base64")

Epoch Fields

If an API field is an epoch timestamp, convert it to ISO date before returning it to the user.

Rule:

• 10 digits -> seconds
• 13 digits -> milliseconds

Example (Node):

new Date(Number(epoch) < 1e12 ? Number(epoch) * 1000 : Number(epoch)).toISOString()

Pagination

page starts at 1

pageSize default = 20

Continue requesting pages while:

items.length < total
