Asynchronous API batches

Queue many supported API requests and collect their results without keeping a client connection open.

POST /v1/batches

How batch processing works

Each batch accepts up to 100 supported public GET requests.
Each item keeps the normal price of its endpoint, and terminal failures are refunded independently.
Job status and results remain available to every member of the account for 24 hours.
An optional HTTPS webhook can notify your system when processing reaches a terminal state.

Example Request

curl -X POST "https://domscan.net/v1/batches" \
  -H "X-API-Key: $DOMSCAN_API_KEY" \
