Web Search for AI

REST endpoints for web search on behalf of AI agents and applications. A single request returns a synthesized answer with links to sources; streaming mode delivers results as they become ready. For deep research with a multi-step agentic loop, use the separate POST /v1/research endpoint.

Which key to choose

Web Search works with two types of keys. The choice depends on whose behalf you send the request.

More on key formats and obtaining a session_token — Keys and authorization.

Providers

The platform offers platform-managed engines billed in Vibe credits, plus BYOK providers billed directly by the vendor. Which engines are available on a given instance, which one is platform-managed, and what it costs depend on the instance configuration. The current list is returned by GET /v1/search/providers.

The current list with the capability matrix and prices — GET /v1/search/providers. Which provider is platform-managed, its price, and the default engine vary from instance to instance. All BYOK providers require your own key, which you add via Your own keys (BYOK). BYOK providers always cost 0 Ꝟ on the platform side.

Supported provider capabilities

The full capability matrix is available in GET /v1/search/providers — capabilities for each provider. The key subsets are shown below in three tables, one per group.

Modes and streaming

Progressive streaming emits intermediate thinking / tool_call / answer_delta events. Buffered streaming sends start and done; in research mode, provider events arrive between them: tool_call and tool_result from tavily, section_complete from linkup.

Synthesized answer and formatting

For brave, the answer field is returned only with search_depth: "advanced", via the optional summarizer. In basic it is null.

Filters

When the selected provider does not support a passed filter, the request completes without error — the filter is ignored. The response carries an X-Search-Filters-Ignored header with the list of skipped fields:

X-Search-Filters-Ignored: include_domains,time_range

For brave with include_answer: true and search_depth: "basic", an additional X-Answer-Not-Supported: brave-search-does-not-synthesize-answers header is returned, and the answer field in JSON is null. In advanced mode the same provider engages the summarizer and returns a populated answer.

When to choose which provider

Quick guidelines:

• bitrix-search — platform web search, requires no key of your own (billed in Vibe credits). Returns a synthesized answer with sources — ready-made RAG output for AI agents, with no separate assembly step. Its specific capabilities (the research mode, progressive SSE streaming, filters) depend on the instance — the exact matrix is in GET /v1/search/providers.
• tavily — domain filters (include_domains / exclude_domains), publication time window (time_range), numeric relevance score (score). A universal choice for general-purpose queries.
• brave — web search without answer synthesis by default; the summarizer is enabled in advanced mode. Suitable for privacy-focused queries.
• exa — neural/semantic search. Suitable for research tasks that need semantically related pages rather than an exact keyword match.
• you-com — the only provider with follow-up questions in research mode.
• linkup — real-time web crawl (liveData: true), suitable for queries about events from the last few hours.
• perplexity — Sonar models, OpenAI-compatible format, deep research with citations.
• jina — research mode only, an iterative "search → read → think" loop. Not available via POST /v1/search.
• z-ai — search without a synthesized answer, returns results with publication dates.

Quickstart

A minimal call to POST /v1/search: the question text in the query field and basic mode. The response contains a synthesized answer and a results array with the pages found; whether citations are included depends on the instance engine — see the capability matrix. When to switch to advanced — see How to choose the depth.

curl -X POST https://vibecode.bitrix24.com/v1/search \
  -H "X-Api-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "what is new in Cursor IDE",
    "search_depth": "basic",
    "max_results": 5
  }'

Response:

{
  "query": "what is new in Cursor IDE",
  "provider": "bitrix-search",
  "search_depth": "basic",
  "answer": "The latest update in Cursor IDE, specifically Cursor 3, introduces a unified workspace for building software with agents, featuring a faster, cleaner, and more powerful interface with a multi-repo layout, seamless handoff between local and cloud agents, and the option to switch back to the Cursor IDE at any time. …",
  "results": [
    {
      "id": 1,
      "url": "https://cursor.com/blog/cursor-3",
      "title": "Meet the new Cursor · Cursor",
      "content": "...",
      "score": 0.8565368,
      "publishedDate": null
    },
    {
      "id": 2,
      "url": "https://thenewstack.io/cursor-3-demotes-ide",
      "title": "Cursor's $2 billion bet: The IDE is now a fallback, not the default - The New Stack",
      "content": "...",
      "score": 0.8259413,
      "publishedDate": null
    }
  ],
  "images": [],
  "ignored_filters": ["lang"],
  "search_id": "ws_20261021221143_d248ca4d",
  "upstream_search_id": null,
  "cost_vibes": 0.02,
  "duration_ms": 2670
}

Citation markers such as [1], [2] in the answer field, when the engine adds them, correspond to results[].id values. The provider value in the response (here bitrix-search) depends on the instance — without an explicit provider, the request goes through the default engine configured on the instance. The current default is shown by the defaultProvider field in GET /v1/me.

Full example

An end-to-end scenario: find the instance's platform provider and the price of basic mode, run a search, and print the answer with the list of sources.

const VIBE_KEY = process.env.VIBE_KEY
const BASE = 'https://vibecode.bitrix24.com/v1'

async function api(method, path, body = null) {
  const opts = { method, headers: { 'X-Api-Key': VIBE_KEY } }
  if (body) {
    opts.headers['Content-Type'] = 'application/json'
    opts.body = JSON.stringify(body)
  }
  const res = await fetch(`${BASE}${path}`, opts)
  const data = await res.json()
  if (!res.ok) throw new Error(`${data.error.code}: ${data.error.message}`)
  return data
}

// 1. Find out which provider is platform-managed on this instance and what basic mode costs
const { providers } = await api('GET', '/search/providers')
const platform = providers.find(p => p.platformManaged)
console.log('Platform provider:', platform.slug, '— basic:', platform.pricing.basic, 'Ꝟ')

// 2. Search in basic mode. Without the provider field the request follows the key selection cascade
const result = await api('POST', '/search', {
  query: 'what is new in Cursor IDE',
  search_depth: 'basic',
  max_results: 5,
})
console.log('Answered by:', result.provider, '— charged:', result.cost_vibes, 'Ꝟ')

// 3. Print the answer and the sources: an [N] marker in answer points to the results item whose id equals N
console.log(result.answer)
for (const source of result.results) console.log(`[${source.id}]`, source.title, source.url)

Pairing /v1/search and /v1/ai/chat/completions, where the LLM answers from fresh sources with [N] citation markers, is covered in the recipe Web search + LLM (RAG).

Pricing

Cost is expressed in the platform's virtual currency — Vibe credits (Ꝟ). The charge occurs after a successful provider response. On a provider error the balance is unchanged.

The platform provider's pricing varies from instance to instance — which engine is platform-managed and how many Ꝟ its basic / advanced / research modes cost are returned by GET /v1/search/providers in the pricing field. BYOK providers (tavily, brave, exa, you-com, linkup, perplexity, jina, z-ai) always cost 0 Ꝟ on the platform side — you pay the vendor directly for those requests, at the vendor's own rates.

The cost_vibes field in the response shows the amount actually charged.

Request history broken down by provider, Vibe credits spent by period, and average duration are available on the /search page in your Vibecode account. There you can also add, test, and delete BYOK keys through a visual interface. The "Use" button next to each provider opens a dialog with ready-made snippets in cURL, JavaScript, Python, the TypeScript SDK, and a text prompt for AI assistants.

Rate limit

• 60 requests per minute per Bitrix24 account for POST /v1/search.
• 20 requests per minute per Bitrix24 account for POST /v1/research — deep research takes tens of times longer than a regular search.

The limit is shared by all API keys of the Bitrix24 account — they draw from the same pool. Spreading the load across several keys does not raise the ceiling. The exact value arrives in the x-ratelimit-limit header (the cap is divided across replicas).

When exceeded, 429 RATE_LIMITED is returned.

Endpoint reference

Key selection cascade

When provider is not passed in the POST /v1/search request, the platform selects it in the following order: user key (USER BYOK) → Bitrix24 account key (PORTAL BYOK) → the default engine configured on the instance (shown by the defaultProvider field in GET /v1/me).

For POST /v1/research the cascade works differently. If the provider field is omitted, the server immediately substitutes the default research engine configured on the instance — a USER/PORTAL default for a different provider (e.g. exa) is not considered here. If that engine has no USER, PORTAL, or PLATFORM key, 404 CREDENTIAL_NOT_FOUND is returned. The USER → PORTAL → PLATFORM cascade is applied within the selected provider. To go through a different research provider, pass provider explicitly.

Once you add your own BYOK key with isDefault: true, the platform uses it automatically — the provider parameter can be omitted.

Migration from Tavily

The request schema mirrors the Tavily Search API. Differences:

• Endpoint: https://api.tavily.com/search → https://vibecode.bitrix24.com/v1/search.
• Authorization: the api_key field in the body → the X-Api-Key: YOUR_API_KEY header.
• Added an optional provider field — choice of engine from the available list.
• Added optional fields: topic (general or news) and include_images — request images in the response. Tavily has these capabilities, but other engines do not. Unsupported fields are ignored and listed in ignored_filters.

If you have your own Tavily key, add it via POST /v1/search/credentials and use provider: "tavily" or make the key the default. The other request fields work identically.

System errors

The full list of common API errors — Errors.

Error response structure

{
  "error": {
    "code": "INSUFFICIENT_BALANCE",
    "message": "Insufficient vibes for this search. Top up your account to continue.",
    "userMessage": "Insufficient Vibe credits — top up your balance or add your own BYOK key (see GET /v1/search/providers).",
    "hint": "Add a BYOK key to search for free — see GET /v1/search/providers",
    "required": 5,
    "topupUrl": "https://vibecode.bitrix24.com/r/upgrade?c=ai_quota_copay&sc=api&m=api&t=topup&p=…&e=…&s=…"
  }
}

The userMessage, required, and topupUrl fields are returned on the INSUFFICIENT_BALANCE and BILLING_FROZEN billing errors. The required field is the amount in Ꝟ needed for the request, and topupUrl is a link to top up the balance. The hint field is returned on those same billing errors and on CREDENTIAL_NOT_FOUND, where it explains how to add your own BYOK key for the selected provider.
