How this service works
Takes a call, meeting, dictation or interview of up to 60 minutes and returns its numeric statements as structured data: kind (amount, percent, date, time, duration, quantity, phone, year), the wording as spoken, a normalised value, unit or currency, what the number refers to, the sentence it comes from and its timestamp. A language model classifies; each value must point to an existing sentence whose wording contains it, otherwise it is dropped and counted — so numbers are never invented.
Output
A structured array of numeric statements found in the recording, each containing: the kind (amount, percent, date, time, duration, quantity, phone, year, or other), the wording as spoken, a normalized value, the associated unit or currency, what the number refers to, the full source sentence containing it, and its timestamp within the recording. Numbers not traceable to an actual spoken sentence are excluded; a count of dropped values is also returned.
Example use cases
Financial figures from earnings call
“I have a 52-minute earnings call recording at https://example.com/q3-call.mp3 — can you extract every dollar amount and percentage mentioned, with what each figure refers to and the timestamp where it was said? Language is English.”
Deadlines and dates from project meeting
“Here's a base64-encoded 30-minute project kickoff meeting recording. Extract all the dates and durations that were mentioned so I can build a timeline — include the exact sentence each came from. The language spoken is German.”
Key figures from recorded interview
“I recorded a 20-minute interview with a CFO and I need a structured list of every quantity and amount he mentioned — things like headcount, revenue figures, and growth rates. The file URL is https://example.com/cfo-interview.mp4, and please only return amounts and quantities, not dates or times.”
Technical details
Endpoint
POSThttps://medien.halowerk.com/v1/numbers-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable extraction of numeric statements from spoken audio or video — especially for meetings, calls, interviews, or dictations where figures like prices, percentages, dates, and quantities are spoken and need to be captured with their context and timestamps. It is distinctly useful over generic transcription when the goal is specifically to parse and normalize numbers rather than produce a full transcript, and its hallucination guard (numbers must be anchored to a real spoken sentence) makes it suitable for financial, legal, or compliance-sensitive use cases.
Side effects
- Recording exceeds 60-minute maximum — request rejected
- File URL is inaccessible or returns non-audio/video content — extraction fails
- duration_minutes mismatch with actual file length may affect billing accuracy
- Language detection fails on low-quality or multilingual audio — incorrect classification
- No numeric statements found — returns empty result set
- Base64 payload exceeds 12MB limit — must use URL instead
- Payment not fulfilled via x402 — 402 response returned
