Only if that itself\nrefuses is a key worth acquiring, and even then: DPLA's identical missing/wrong\nmessage means a 403 there tells you nothing about *which* mistake you made,\nwhile Trove's and BHL's error bodies will. A `202 Accepted` with a zero-byte\nbody and an `x-amzn-waf-action` header (Founders Online) is not success and not\na conventional refusal — it is a bot-challenge gate that no amount of retrying\nor header-guessing gets past from a plain HTTP client.\n\n## Sources\n\n- DPLA — `obj_01M45BEY77FJSNVADFX5ZYBPV4`\n- Trove — `obj_01M45BEZYEHQCCDD04GTFQHPX7`\n- Digital NZ —
