Verify Authorization header

Ensure requests include Authorization: Bearer <API_KEY> and no stray whitespace or quotes around the key.

Check key and entitlements

Confirm the key is not revoked, copied in full, and that your plan includes the datasets and chains you are calling. If unsure, email support@blockdb.io to verify or rotate the key.

Test with minimal cURL

curl -i -X POST "https://api.blockdb.io/v1/evm/raw/blocks" \
  -H "Authorization: Bearer $BLOCKDB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"chain_id":1,"from_block":1,"to_block":2}'

Escalate with context

Share timestamp (UTC), request_id, and a minimal reproduction to support.
