Turn the speech in a public Facebook video, Reel or video post into text, from its link. You get the transcript and the video length in seconds. A video where nobody speaks comes back without text.

Price $0.96 per 1,000 requests ($0.000958 per call). Failed calls and empty results are not charged. Synchronous. For slow jobs add "mode": "async" to the body, take the job_id and poll.

Please help me write a data collection script with the EveryInfra Facebook Video post transcripts endpoint (facebook/post_transcript).

How the endpoint works:
- Request: POST https://api.everyinfra.com/api/v1/social with the header Authorization: Bearer <API key>. Read the key from the EVERYINFRA_API_KEY environment variable and never hard-code it.
- In the request body, set platform to facebook and action to post_transcript, and put the parameters inside params.
- Required parameters:
  - url: A public video, Reel or video post link, such as https://www.facebook.com/reel/<ID>/.
- Returns one object. Main fields: id, url, text, duration_seconds, duration_sec.
- Example request body:
{
  "platform": "facebook",
  "action": "post_transcript",
  "params": {
    "url": "https://www.facebook.com/reel/2166091230582141/"
  }
}
- Price: $0.96 per 1,000 requests; failed and empty results are not charged.
- For dozens or hundreds of targets, add "mode": "async" to the body: you get a job_id at once and poll GET https://api.everyinfra.com/api/v1/jobs/{job_id} for the result.
- On 422, fix the request using the suggested parameter names and allowed values in the error; on 429 or 503, wait for Retry-After and try again.

Before writing code, ask me which targets I need, how many, which fields, and what output format I want; then confirm the plan and the rough cost with me.

No sample response is available for these parameters yet. This preview shows the response shape and fields from the API definition, with … as placeholders; it is not the result of a live call.

json

{
  "id": "req_…",
  "platform": "facebook",
  "action": "post_transcript",
  "results": {
    "id": …,
    "url": …,
    "text": …,
    "duration_seconds": …,
    "duration_sec": …,
    "platform": …

  "billing": {
    "charged": …,
    "charged_usd": …,
    "balance_after_usd": …,
    …
  },
  "quota": { … }
}

Response fields

Business data is in results. The table lists the fields a record can contain; values the platform does not show are never made up.

Field	Meaning
`id`	The record's unique ID on the platform. Unique only within one platform; IDs can repeat across platforms.
`url`	Link to the record on the platform.
`text`	Body text with HTML removed, returned in full and never cut short (on a few platforms the list results themselves carry only an excerpt; the platform's field notes say so).
`duration_seconds`	Duration in seconds. null for content that is not video or audio.
`duration_sec`	Keeps the platform's own meaning
`platform`	Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).
