Address	`https://api.hanzo.ai/v1/event/errors`
Method	`GET`
Operation	`get_event_errors`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Returns the caller org's most recently captured errors, newest first. The error-tracking read view over event.error — the plane table the write core's error facts land in (errors are DELIBERATELY not on event.event) — each with its captured exception surfaced from the attributes map as a first-class field.

The org is the validated principal's — never a parameter — and this read requires a real bearer, NEVER the write-only publishable key: pk- can attribute a write and can read nothing. 401 without a validated bearer, 503 when the warehouse is unreachable.

Request

1 field.

Field	In	Type	Required	Description
`limit`	query	integer	—	Limit is how many rows to return, newest first.

Response

Status	Body	Meaning
`200`	event.errorList	ok
`default`	problem-details	refused

200 body — 13 fields.

Field	In	Type	Always	Description
`data`	body	event.capturedError[]	—	Data is the errors, newest first.
`data[].distinctId`	body	string	—	DistinctID is the person/visitor the error is attributed to.
`data[].event`	body	string	—	Event is the event name the error was stored under, e.g. $error.
`data[].exception`	body	any	—	Exception is the captured error itself — the {type, message, stack, handled} object, already redacted at the fold point.
`data[].id`	body	string	—	ID is the row's stable event id — the client's own idempotency id when it sent one, else the server-minted one.
`data[].library`	body	string	—	Library is the client SDK that reported the error.
`data[].libraryVersion`	body	string	—	LibraryVer is that SDK's version.
`data[].path`	body	string	—	Path is the URL's path component.
`data[].product`	body	string	—	Product is the surface that emitted the error.
`data[].properties`	body	any	—	Properties is the row's whole property bag, returned verbatim as stored — any JSON object, $exception included.
`data[].sessionId`	body	string	—	SessionID groups the events of one visit.
`data[].timestamp`	body	string	—	Timestamp is when the error was captured, RFC3339 UTC.
`data[].url`	body	string	—	URL is the full page address the error fired on.

Failure carries the platform error shape — see Errors.

MCP reaches event through the event tool, which names its 9 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "get_event_economic"
         }
       }
     }'
