Runbook · API Authentication Failures

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}'

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 fully from dashboard.blockdb.io, and that your plan includes the datasets and chains you are calling. Create a new key or rotate if unsure.

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.
