# Retrieve Assemblyai Transcript

`GET /api/assemblyai/v2/transcript/{transcript_id}`

Centralized respan_params initialization and backward-compat layer.

This mixin is the SINGLE initialization point for ``respan_params``.
It runs ``_initialize_respan_params()`` BEFORE ``super().initial()`` so
that by the time the throttle runs, ``respan_params`` is a fully resolved
dict.  Downstream code (throttle, preprocessing, view handler) only
**enriches** the existing dict — they never need to create it.

Initialization order::

    _initialize_respan_params()   ← legacy rename + header parse + metadata
        ↓
    super().initial()             ← throttle ENRICHES the existing dict
        ↓
    view handler                  ← billing, security strip, etc.

Responsibilities consolidated here (previously scattered across 4 callsites):
1. Legacy header rename  (X-Data-Keywordsai-Params → X-Data-Respan-Params)
2. Parse X-Data-Respan-Params header  (base64 → dict)
3. Legacy body rename  (keywordsai_params → respan_params)
4. Form data handling  (JSON string → dict)
5. Metadata nesting  (passthrough endpoints — Anthropic, Google, etc.)
6. Merge: {**header_params, **body_params}  (body wins on field conflict)
7. Add request_url_path from request.META['PATH_INFO']
8. Guarantee request.data[RESPAN_PARAMS_KEY] is always a dict

Safe for protobuf endpoints: body adaptation is skipped when request.data
is not a dict; header adaptation always runs.

Usage::

    class MyChatView(AdaptRespanParamsMixin, APIView):
        ...
