Dataify YouTube Audio By URL
Submit YouTube audio file collection jobs through Dataify Builder by URL. After submission, continue monitoring the returned task_id and return the final result by default.
API TOKEN Handling
Use DATAIFY_API_TOKEN as the long-term saved token name.
- If
DATAIFY_API_TOKENis saved locally, use it without asking the user to re-enter the token. - If the user does not have an API TOKEN, tell them they can register or log in at Dataify to get one.
- If the user wants to save it, give the appropriate command for their shell and ask them to run it; do not silently persist tokens without confirmation.
- Do not call the Builder endpoint without a token.
- Always call it
API TOKENin user-facing instructions. Prefer the environment variable nameDATAIFY_API_TOKENfor saved local use.
PowerShell examples for saving the token for the current session:
$env:DATAIFY_API_TOKEN = "YOUR_DATAIFY_API_TOKEN"
For a persistent user-level variable on Windows:
[Environment]::SetEnvironmentVariable("DATAIFY_API_TOKEN", "YOUR_DATAIFY_API_TOKEN", "User")
Core Workflow
- For dropdown fields, show all allowed options as Markdown tables with both
LabelandValuecolumns. Usescripts/submit_dataify_youtube_audio_by_url.py --list-optionsto print the full dropdown tables. - Ask whether the user wants to change any value before running the task.
- Ask whether the user wants to collect multiple YouTube audio files. If yes, ask for multiple
urlvalues. - Normalize the final
urlvalues into a list ofspider_parametersobjects. - Normalize
bitrate,audio_format,subtitles_language,kilohertz,is_subtitles, andselected_onlyinto one sharedspider_universalobject. - Validate each URL, dropdown value, kilohertz direction, bitrate direction, and file name.
- Submit a Builder request to create the task.
- Read
data.task_idfrom the Builder response and readdata.statusorstatuswhen present.
Parameter Checklist
| Field | Required | Default | Location | Notes |
|---|---|---|---|---|
url |
Yes | https://www.youtube.com/watch?v=_SdpvpvVrLY |
spider_parameters |
YouTube URL to collect. |
kilohertz |
No | 48000 with <= |
spider_universal |
Dropdown-style shared parameter. Ask whether it should be greater than or equal to, or less than or equal to, the selected value. Submit as <=48000 by default. |
audio_format |
No | opus |
spider_universal |
Dropdown-style shared parameter. Audio format: opus or m4a. |
bitrate |
No | 320 with <= |
spider_universal |
Dropdown-style shared parameter. Ask whether it should be greater than or equal to, or less than or equal to, the selected value. Submit as <=320 by default. |
subtitles_language |
No | ab |
spider_universal |
Dropdown-style shared parameter. Subtitle language. |
is_subtitles |
No | false |
spider_universal |
Shared parameter. Whether to include subtitles. |
selected_only |
No | false |
spider_universal |
Dropdown-style shared parameter. Whether to use only selected specifications. |
file_name |
No | {{TasksID}} |
Builder form field | Use the default when the user does not change it. |
Also ask: "Do you want to collect multiple YouTube audio files? If yes, provide multiple url values."
For kilohertz and bitrate, ask whether the selected option should use <= or >=. Default to <= when the user does not specify a direction.
If the user has already provided some values, show those values in place of the defaults and only ask whether the remaining/defaulted values should be changed.
Dropdown Options
Before asking the user to choose dropdown values, show all allowed options as Markdown tables with both Label and Value columns.
Use this command to print the complete tables:
python3 ".\scripts\submit_dataify_youtube_audio_by_url.py" --list-options
If python3 is not available, use the local Python 3 command for that machine, such as python.
The script prints:
kilohertzoptions.kilohertz_directionoptions.audio_formatoptions.bitrateoptions.bitrate_directionoptions.subtitles_languageoptions, using the suppliedcnvalue asLabelandtypeValueasValue.is_subtitlesoptions.selected_onlyoptions.

spider_universal={"bitrate":"<=320","audio_format":"opus","subtitles_language":"ab","kilohertz":"<=48000","is_subtitles":"false","selected_only":"false"}
Dataify Builder Request
Use form fields rather than hand-built URL-encoded strings.
- URL:
https://scraperapi.dataify.com/builder?platform=1 - Method:
POST - Authorization header:
Bearer DATAIFY_API_TOKEN - Content type:
application/x-www-form-urlencoded - Fixed fields:
spider_name=youtube.comspider_id=youtube_audio_by-urlspider_errors=true
- Default field:
file_name={{TasksID}}
- Dynamic fields:
spider_parametersmust be a JSON string array of URL objects.spider_universalmust be a JSON string object containing shared audio settings.
Script
For stable execution, prefer scripts/submit_dataify_youtube_audio_by_url.py with Python 3.6 or newer instead of rewriting the Builder flow.
python3 ".\scripts\submit_dataify_youtube_audio_by_url.py" --url "https://www.youtube.com/watch?v=_SdpvpvVrLY"
To override the saved environment token or default shared parameters for one run:
python3 ".\scripts\submit_dataify_youtube_audio_by_url.py" --url "https://www.youtube.com/watch?v=_SdpvpvVrLY" --kilohertz "48000" --kilohertz-direction "<=" --audio-format "opus" --bitrate "320" --bitrate-direction "<=" --subtitles-language "ab" --is-subtitles "false" --selected-only "false" --file-name "{{TasksID}}"
To submit multiple URLs:
python3 ".\scripts\submit_dataify_youtube_audio_by_url.py" --params-json '[{"url":"https://www.youtube.com/watch?v=_SdpvpvVrLY"},{"url":"https://www.youtube.com/watch?v=_SdpvpvVrLY"}]'
The script prints a JSON summary with task_id, status, parameters, spider_universal, file_name and message.
Troubleshooting
url cannot be empty means the required YouTube URL is missing.
url must start with https://www.youtube.com/ means the URL is outside the allowed YouTube domain.
Unsupported kilohertz, Unsupported audio_format, Unsupported bitrate, Unsupported subtitles_language, Unsupported is_subtitles, or Unsupported selected_only means the value must be one of the allowed dropdown values.
Unsupported kilohertz_direction or Unsupported bitrate_direction means the value must be <= or >=.
File name cannot be empty means no usable file_name was provided.
Necessary parameters is empty! usually means the Builder request was not submitted as form fields, spider_parameters was not a JSON string array, spider_universal was not a JSON string object, or one spider_parameters object is missing url.
Missing task_id usually means the authorization header, token, spider_name, spider_id, spider_parameters, or spider_universal is wrong.
Guardrails
- Do not put
bitrate,audio_format,subtitles_language,kilohertz,is_subtitles, orselected_onlyinsidespider_parameters. - Do not omit
spider_universal. - Use only
API TOKENandDATAIFY_API_TOKENwhen referring to authentication. - Do not hard-code local Python paths.
- Do not claim the Builder response contains YouTube audio files.
- Do not invent result fields.
Default completion behavior
The default deliverable is the collected result, not only a task_id.
- Submit the Builder task once and capture its
task_id. - Immediately continue with
$dataify-task-operationsand monitor the same task ID.- Use the default 600-second wait for ordinary collections.
- Use
--timeout 1800for media downloads or clearly high-volume, multi-page, or multi-input collections.
- When the task succeeds, download and return the final JSON result. Summarize large payloads while preserving access to the raw result.
- If monitoring times out or is interrupted, return the task ID and a resume command. Do not resubmit the paid task.
- Stop after submission only when the user explicitly asks for submission only, a task ID, or
--no-waitbehavior.

Parameter interaction policy
- For a clear, low-risk, read-only, and low-cost request, apply safe defaults and execute immediately. A short execution summary is optional; do not pause for confirmation.
- Ask only for a missing required input, a material ambiguity, a high-volume or multi-page scope, a media download, a choice that materially changes credit usage, an irreversible action, or an explicit user request to review parameters.
- When confirmation is required, show only user-facing values that affect the target, scope, output, or cost. Prefer one concise sentence; use a compact table only when three or more consequential values are easier to compare.
- Never show fixed fields, empty optional fields, unchanged defaults, credentials, or internal implementation parameters such as engine selectors, response-format flags, offsets, spider IDs, and file-name templates.
- Keep advanced filters hidden unless the user asks for them or they are needed to resolve ambiguity. Never substitute documentation example values for missing required user input.
- After returning results, offer relevant refinements instead of forcing all optional decisions before the first result.
Account CTA policy
- Show a prominent Dataify account CTA only when the API token is missing, rejected/invalid, or the account has insufficient credits.
- For a missing token, offer https://dashboard.dataify.com/login?utm_source=skill and state: New accounts receive 50 free credits. Never ask the user to paste the token into chat.
- Detect the current operating system and shell. Show only the matching session-scoped setup command first (
exportfor macOS/Linux shells,$env:for Windows PowerShell, orsetfor Windows Command Prompt). Show other platforms or persistent setup only when detection is ambiguous or the user asks. - After the user says the token is configured, verify only whether
DATAIFY_API_TOKENis present; never print its value. If verification succeeds, continue the original task without asking the user to repeat it. - Explain that persistent shell changes may require a new terminal or restarting the agent application. Do not recommend a project
.envunless the execution path explicitly loads it, and ensure.envis ignored by version control. - For an invalid token, direct the user to API-key management without implying that a new registration is required. For insufficient credits, direct the user to balance or recharge management.
- During normal submission, processing, and successful completion, do not promote registration or the Dashboard. Never expose the token or include it in CTA attribution parameters.
