Billing

Billed by returned fill objects

userTwapSliceFills responses are billed by the number of fill objects returned, not as one response per HTTP request. A response with 100 fills counts as 100 responses/API credits.

Requests that return an empty array are billed as 0 responses/API credits and do not count against usage. Error responses are not charged.

JSON-RPC Example

curl -X POST "https://api-hyperliquid-index.n.dwellir.com/YOUR_API_KEY/jsonrpc" \
  -H "content-type: application/json" \
  -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "userTwapSliceFills",
  "params": {
    "user": "0x1111111111111111111111111111111111111111",
    "limit": 100
  }
}'

Response

REST /info responses return an array directly. JSON-RPC responses return the same array under result. Empty matches return []; they are not errors.

Each fill row is a normal fill object with twapId populated. txIndex is the block-local fill event index from node_fills_by_block.
