# Declared SDK error codes

API `6.4.1` · SDK `6.5.3` · Docs `6.5.3`

Generated from explicit SDK error declarations. Server/provider responses can contain additional codes. Follow the [failure and reconciliation contract](/docs/agent-execution.md) and the relevant feature guide. An ID on an error is not proof of delivery; never log private payloads, credentials or payment proofs.
