# NousResearch/hermes-agent · API error body extraction and classification fixes

## Open now

- Nothing open on GitHub.

Multiple fixes and a feature addressing how wrapped or nested API errors are inspected, with cause-chain walking to correctly extract error bodies and improve error classification for failover logic. One member about preserving tool-turn context appears adjacent but not fully aligned with the core theme.

## TL;DR

- 7 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 5 PR(s) closed without merging.
- A fix was merged to main in PR #53582. Verify it addresses your case.
- **Recommended:** read PR #53582 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-53582`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.29`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.

## Closed / duplicate issues

- #14195: Wrapped API errors lose nested body details and misclassify transient 402s as billing failures
