The Answer Agent researches a natural-language question across Tako’s knowledge and the live web, then returns a synthesized, opinionated answer (markdown) with the citations and cards that back it. Use it for open-ended questions that need reasoning across many entities. See the Answer Agent guide for examples, citations, streaming, threads, and sources.

​
Notes

  • To authenticate, send your Tako API key in the X-API-Key header. Store it as an environment variable rather than hardcoding it.
  • The agent is asynchronous: this endpoint returns 202 with an AnswerAgentRun whose status is queued. Poll Poll an Answer Agent run until status is completed or failed.
  • To stream progress live instead of polling, send Accept: text/event-stream. The response is then a Server-Sent Events stream of AnswerAgentStreamEnvelope events. See the coding-agent reference.
  • Frozen contract: the Answer Agent never accepts an output_schema and never returns structured output or inline data — the result is answer + cards + citations + metadata. For structured data, use the Search Agent.

​
Choosing sources

source_indexes is optional and defaults to ["data", "web"] — both. Pass it only to restrict: ["data"] (curated knowledge graph only) or ["web"] (open web only). The legacy value "tako" is a synonym for "data".

​
Continuing a thread

Pass the thread_id from a prior run to ask a follow-up in the same conversation. Omit it to start a new thread. A thread is pinned to the Answer Agent and to one set of source_indexes.

Authorizations

​
X-API-Key
string
header
required

Body

application/json

Request body for POST /v1/agent/answer/runs.

Frozen contract: NO output_schema / structured outputs, NO inline data — ever. Cards are the only data-export path (via /v1/contents).

​
query
string
required

Natural-language request for the answer agent.

Example:

"How have American Airlines' margins held up against fuel shocks?"

​
thread_id
string<uuid> | null

Existing thread to continue (follow-up). Omit to start a new thread.

​
effort
enum<string>
default:medium

Answer-agent effort. Only 'medium' is currently supported.

Available options:
medium
​
source_indexes
enum<string>[]

Which sources the agent may use: 'data' (curated knowledge) and/or 'web' (open-web search). Defaults to ['data', 'web']. The legacy value 'tako' is accepted as a synonym for 'data'.

Available options:
data,
web
Examples:
["data"]
["web"]
["data", "web"]
​
locale
string
default:en-US

BCP-47 locale. Drives the language of the agent's answer and the locale used when rendering card preview images. Defaults to en-US.

​
timezone
string | null

IANA timezone (e.g. 'America/New_York') used to render dates/times in card preview images. Does not affect the returned data.

​
output_settings
AgentOutputSettings · object | null

Settings controlling the response/rendering.

Response

Run dispatched. With Accept: application/json, poll GET /v1/agent/answer/runs/{run_id} for status. With Accept: text/event-stream, the response is an SSE stream of AnswerAgentStreamEnvelope events terminating at stream_done; if the stream ends without an agent_result event, poll GET /v1/agent/answer/runs/{run_id} for terminal status.

The answer-agent run resource returned by dispatch (202) and poll (GET).

​
run_id
string
required
​
status
enum<string>
required
Available options:
queued,
running,
completed,
failed
​
created_at
string
required
​
object
string
default:agent.run
Allowed value: "agent.run"
​
thread_id
string | null
​
completed_at
string | null
​
result
AnswerAgentResult · object | null

Final answer-agent output. answer is markdown prose with [n] citation markers; citations is the unified top-level registry the [n] markers join; cards reuse the sibling TakoCard; metadata carries definitions/assumptions/ methodology. NO inline data, NO structured output, NO web_results — ever. Prose-only (empty cards) is legitimate.

​
error
ErrorObject · object | null
​
usage
Usage · object | null

Cost-plus usage for one metered request. total_cost_usd is always present (the total quoted charge). compute / data are the additive breakdown and appear only where they apply. See module docstring for the quote-vs-drawdown caveat and the total == compute + data invariant.

​
request
AnswerAgentRunRequest · object | null

Request body for POST /v1/agent/answer/runs.

Frozen contract: NO output_schema / structured outputs, NO inline data — ever. Cards are the only data-export path (via /v1/contents).
