# Search traces (TraceQL, or the filter params)

`POST /preview/traces/queries`

## Request

- Base URL: `https://autoresearch.sfcompute.com`
- URL: `https://autoresearch.sfcompute.com/preview/traces/queries`
- Auth: HTTP bearer

Find traces: the platform emits one per node provision (queued → provisioning → ready) and one per job lifecycle (build, queue wait, each attempt) with zero setup - boot-phase and queue-wait diagnoses become a waterfall instead of snapshot archaeology - and your own OTLP spans land beside them. Filter by mission / run / min_duration for the common case, or pass full TraceQL. Returns trace summaries; get_trace fetches the span tree.

## Query parameters

- `workspace` string

## Request body

- object
  - `end` string, nullable: Range end, RFC3339 (default: now).
  - `limit` integer, nullable: Max traces returned (default 20, cap 100).
  - `min_duration` string, nullable: Filter: minimum total trace duration, e.g. "5s", "500ms".
  - `mission` string, nullable: Filter: mission name.
  - `query` string, nullable: Full TraceQL (optional - the filter params below compose the query for the common case), e.g. { resource.mission = "x" } | count() > 2.
  - `run` string, nullable: Filter: one run - a job-/cmd-/ses- scope id.
  - `start` string, nullable: Range start, RFC3339 (default: one hour before `end`).

## Response `200`

The capability's JSON result.

- Result: The capability's result: the same object the MCP tool returns as structuredContent. Resources carry an `object` type discriminator and an immutable id; money is integer micro-dollars in `*_usd_micros` fields.
  - `object` string: The resource type, when the result is one resource.

## Other responses

- `400`: Malformed request: bad JSON, a parameter that does not parse, or a value outside its range. Code `invalid`.
- `401`: No bearer token, or one this API cannot verify. Code `unauthenticated`.
- `403`: Authenticated, but the token's scopes or the account's role do not reach this operation. The message names the scope word to request. Code `forbidden`.
- `404`: No such route. Code `not_found`; the body names the OpenAPI document.
- `422`: A well-formed request the platform declined: no such node, a cap reached, a state that forbids the move. The message says which, and what to do instead. Code `refused`.
- `429`: Over this door's per-customer budget. Wait `Retry-After` seconds. Code `rate_limited`.
- `500`: Our fault. Retry; if it persists, quote the request-id. Code `internal`.
