All API and transport failures raise AgentMailError:
python
from agentmail_client import AgentMailError
try:
client.send_mail(to="bad@example.com", subject="test", body="hi")
except AgentMailError as e:
print(e.status_code) # HTTP status, or None for transport errors
print(e.body) # parsed JSON error body| Status | Usual cause |
|---|---|
| 401 | Missing, malformed, or revoked token. |
| 403 | Valid token without access to that agent or resource. |
| 404 | Unknown message, agent, or attachment index. |
| 409 | Idempotency or directory key version conflict. |
| 429 | Rate limited — back off and retry. |
