# Upsert mid-call partial index (utterances → fact/promise hints). Path to ≤400ms whisper; ≤600/hour/key → 429; idle $0.

`GET /v1/pbx/index/partial`

## Request

- Base URL: `https://api.temsor.com`
- URL: `https://api.temsor.com/v1/pbx/index/partial`
- Auth: one of:
  - HTTP bearer
  - API key in header `x-api-key`

POST /v1/pbx/index/partial {call_id, text?, speaker?, t_ms?, is_final?, live?, end_call?, promote?}. Streams partial STT queue into accumulating Fact/Promise hints while the call is live. No Temsor STT/LLM — customer posts text. Managed SaaS in-call index; no DID sales. Own PBX optional footnote. Idle $0.

**Credits per call:** 1 · **Operation id:** `pbx_index_partial`

In the GET form every field is a query parameter; object and array fields are JSON-encoded.

## Query parameters

- `call_id` string, required: Live call id to upsert partial index for.
- `text` string: Partial utterance / snippet (customer STT or demo). Empty = metadata-only.
- `speaker` string, nullable
- `t_ms` integer, nullable
- `is_final` boolean: Finalized utterance span (vs interim).
- `live` boolean: Default true while call is live.
- `end_call` boolean: Mark live=false; idle $0 for this call.
- `promote` boolean: Promote heuristic hints into durable Promise/Fact docs.
- `pbx_id` string
