You can use cURL or any other http client to run inferences:

curl -X POST \
    -d '{"question": "Who jumped?", "context": "The quick brown fox jumped over the lazy dog."}'  \
    -H "Authorization: bearer $DEEPINFRA_TOKEN"  \
    -H 'Content-Type: application/json'  \
    'https://api.deepinfra.com/v1/inference/deepset/roberta-large-squad2'

which will give you back something similar to:

{
  "answer": "fox",
  "score": 0.1803228110074997,
  "start": 16,
  "end": 19,
  "request_id": null,
  "inference_status": {
    "status": "unknown",
    "runtime_ms": 0,
    "cost": 0.0,
    "tokens_generated": 0,
    "tokens_input": 0
  }
}
