API pricing

A run's price is additive: a small base fee, a download charge per artifact fetched, and, when you pass a schema, an AI rate per second per modality. Model-independent. 1 credit = $0.0001. Your first top-up earns 1,000 bonus credits.

Base fee

Every fresh pipeline run costs 50 credits ($0.0050). It covers the probe, metadata, thumbnail and description, which every run includes. Cached results (previously extracted URLs) are free.

Download rates

Charged per artifact you request, on download-only runs (parts) and on AI runs alike (an AI run downloads whatever its inputs need). Artifacts that turn out unavailable (a video with no subtitles, hidden comments) are refunded automatically on completion.

AI rates

total = base + Σ(download rates) + Σ(selected modality rate × video seconds). Download-only runs (no schema / schemaId) skip the AI component entirely; probes are free.

The probe is the canonical quote

POST /v1/probe with your URL and intended inputs returns the exact price that the matching submit will debit:

POST /v1/probe
{ "url": "https://...", "inputs": ["transcript", "comments", "video"] }

  "durationSec": 212,
  "price": {
    "credits": 716,
    "usd": 0.0716,
    "baseUsd": 0.0050,
    "downloadUsd": 0.0136,
    "downloadBreakdown": { "transcript": 0.0010, "comments": 0.0020, "video": 0.0106 },
    "breakdown": { "text": 0.0106, "audio": 0.0000, "video": 0.0424 }
  }
}

Worked example

A 3m32s video (212s) with inputs: ["transcript", "comments", "video"]:

• base fee: $0.0050
• downloads (transcript + comments flat, video per-second): $0.0136
• AI text (transcript + comments, charged once): $0.00005 × 212s = $0.0106
• AI video: $0.0002 × 212s = $0.0424
• audio: $0. The video already carries the audio track, so it isn't billed separately.
• Total: $0.0716 = 716 credits.

Debits, refunds and caching

• Credits are debited up-front at submit, atomically with creating the extraction.
• Failed extractions are refunded in full, automatically.
• When the platform hides the video duration (durationSec: null on the probe), the worst-case 300s is debited and the difference is refunded once the real duration is known. You never pay more than the worst case.
• If an identical extraction (same URL, schema and inputs) completed recently, the result is reused and nothing is charged (creditsDebited: 0, cached: true).

First top-up bonus

Your first top-up, whatever the amount, comes with 1,000 bonus credits on top of what you buy, once per account. At the text rate that's about 33 extra minutes of transcript extraction. Top up from the billing page. See also the general pricing guide.
