Batch Requests

That is, sending multiple requests in an array at the same time is called batch processing, see JSON-RPC 2.0 Specification.

Batch requests are counted as: total number of arrays + 1. For example: the following array contains 10 batches, then these 10 batches will be counted in the daily request limit, plus 1 request of itself, so it will be counted as 11 requests.

curl https://eth-mainnet.solarpath.io/v1/YOUR-API-KEY \
    -X POST \
    -H "Content-Type: application/json" \
    --data '[
	{"jsonrpc": "2.0", "id": 1, "method": "eth_blockNumber", "params": []},
	{"jsonrpc": "2.0", "id": 2, "method": "eth_blockNumber", "params": []},
	{"jsonrpc": "2.0", "id": 3, "method": "eth_blockNumber", "params": []},
	{"jsonrpc": "2.0", "id": 4, "method": "eth_blockNumber", "params": []},
	{"jsonrpc": "2.0", "id": 5, "method": "eth_blockNumber", "params": []},
	{"jsonrpc": "2.0", "id": 6, "method": "eth_blockNumber", "params": []},
	{"jsonrpc": "2.0", "id": 7, "method": "eth_blockNumber", "params": []},
	{"jsonrpc": "2.0", "id": 8, "method": "eth_blockNumber", "params": []},
	{"jsonrpc": "2.0", "id": 9, "method": "eth_blockNumber", "params": []},
	{"jsonrpc": "2.0", "id": 10, "method": "eth_blockNumber", "params": []}
     ]'

Batch requests are limited to 100 requests per batch, and requests above this limit may be unreliable. Recommended value is within 30 requests.
