For pay-per-call access without an API key, use the x402 host instead (same paths): https://x402-data-tools.prd.arrays.org/api — see Nanopayment.

Authentication

Send your API key in the X-API-Key header on every request:

curl "https://data-tools.prd.arrays.org/api/v1/stocks/company/detail?symbol=AAPL" \
  -H "X-API-Key: $ARRAYS_API_KEY"

Response envelope

Every endpoint returns the same shape:

{
  "success": true,
  "request_id": "req_abc123",
  "data": [ ... ]
}

data is always an array, even for single-record results. Paginated endpoints add a pagination object (limit, cursor, has_more) alongside data.

Endpoint catalog
