HTTP status codes

CodeDescription
200Default HTTP response for both success and many business errors. Only outer JSON code 0 indicates success or asynchronous acceptance; inspect data for the result.
429Execution admission rate limit; honor Retry-After when present.
503Execution admission is temporarily unavailable; honor Retry-After when present.
Opt-inX-Nexscope-Http-Status: semantic maps controller-handled business errors to HTTP status on run and task routes. Pre-authentication failures, such as a missing API key (code 11209), may still return HTTP 200 before this mapping. Always check the outer JSON code; malformed requests and infrastructure failures may also return non-200 HTTP responses.

NameTypeRequiredDescription

Partial or complete YouTube search query
Example: mr beast

Social data contract

Use your Nexscope API key. No supplier credentials are required. Requests reject unknown fields, including pageSize. URLs require HTTPS and an exact supported platform host and resource path. Documented YouTube video URLs may use youtu.be; other short links are unsupported. Check the request schema for supported fields and defaults.

Each request fetches one page. Continue manually with the returned nextCursor, or nextPage for Instagram Reels (pages 1–11). Cursors are opaque, unchanged strings up to 65536 UTF-8 bytes. No automatic pagination, retry, media download or transcription is performed. Repeated requests may purchase data again.

Resource status is independent of HTTP and billing: AVAILABLE, PARTIAL, PRIVATE, RESTRICTED, NOT_FOUND, NO_TRANSCRIPT or UNKNOWN can accompany code 0. Unknown values remain null; arrays remain empty arrays. fetchedAt is the response observation time; sourceFetchedAt is null without source evidence.

usage.billingStatus is NOT_CHARGED, SETTLED or UNKNOWN; chargedCredits is null when unconfirmed. Unknown charges never mean free. Completed lookups have a minimum charge of 10 credits, including cached, no-caption and unavailable-resource results; check API usage records for the actual charge. Parameter errors and unpublished APIs use the standard error envelope; upstream failures use code 13007, rate limits 429 and timeouts 408. Always check code and msg.

Data source, freshness, and limitations

Source, freshness, coverage, rate limits, and estimation notes are not specified in this API definition unless they appear in the request or response field documentation above. Do not assume official marketplace data or real-time freshness when it is not explicitly documented.

Step 1 of 2 · Connect your MCP client

MCP

V2 recommended

Connect remote agents through the standard MCP 2025-11-25 Streamable HTTP endpoint. Use OAuth 2.1 Authorization Code with PKCE, or an API key for compatibility.

POST https://api.nexscope.ai/mcp
MCP-Protocol-Version: 2025-11-25
Content-Type: application/json
Authentication

OAuth clients request the mcp:tools scope. The endpoint's 401 response advertises protected-resource metadata for authorization discovery.

Step 2 of 2 · Call the tool

    "arguments": {

Legacy MCP v1

Existing API-key clients can continue using the compatibility endpoint. New integrations should use MCP v2.

Question

What data can YouTube Search Typeahead provide, and how might I use it?

AI answer

Returns the live search suggestions YouTube displays while a user types. Each result includes the suggested text and whether it is a normal query or a channel. When YouTube returns a channel suggestion, the response also includes its public channel ID, handle, name, and thumbnail.

Data categoryDocumented fieldsHow to use them
RequestqueryProvide the required identifiers, filters, or paging inputs listed in the API document.
Responsedata.data, data.platform, data.resourceStatusInspect returned values and source references; availability depends on the request and upstream source.
  • Review YouTube Search Typeahead.
    • Prompt example: “Retrieve YouTube Search Typeahead for [search phrase]. Summarize only the information actually returned and preserve source links when available. Report private, restricted, missing or partial results explicitly; missing values are not zero.”
  • Create a Brief From Returned Text.
    • Prompt example: “Retrieve YouTube Search Typeahead for [search phrase] and prepare a brief about [my research question] using only text present in the response. Cite the corresponding source links when returned, distinguish quotations from interpretation, and report insufficient text. Do not claim to have read linked pages or infer private information.”
  • Separate Topic Suggestions From Channel Matches.
    • Prompt example: “Get YouTube autocomplete suggestions for [search phrase]. Split query suggestions from channel suggestions, preserving suggested text and the channel IDs or handles actually returned. Use the result to clarify what to search next, not to estimate demand or search volume.”

These are suggested workflows, not completed lookups. Report missing, restricted, or partial data explicitly; verify the live response before making a decision.

Online test

Execute the current API with your API key and JSON payload. Online tests use this site's configured API environment; the Endpoint and copyable examples use the public integration address.

One request fetches one page. Copy nextCursor into cursor, or nextPage into page (1–11 for Reels), then run manually. Repeated requests may purchase data again. Completed lookups have a minimum charge of 10 credits, including cached, no-caption, private, restricted and not-found results. Resource status and actual billing status are independent; null credits are unknown, never free. Check usage.billingStatus, usage.chargedCredits and API usage records for the actual charge.
