}Check the remaining Cite42 balance in USD for the connected account. Free.
Alias of cite42_balance for older integrations. Free.
Get the exact Cite42 price table in USD: per-surface rates, flat-rate tools, workflow maximums, and which tools are free. Use it for cost questions and to estimate a plan before running it. Free.
Get recent Cite42 usage for the connected account: the last calls with their cost and status, plus the remaining balance in USD. Free.
Run a query against AI models (ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews) and return each model's answer along with the sources it cited. Priced per AI surface queried. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Measure how a set of brands/competitors rank in AI answers for a query: mention rate, average position, and a per-model breakdown across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. Its requestId can be passed to cite42_recommendations when the user asks for improvement advice. Priced per AI surface queried. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Compare one primary brand head-to-head against a competitor set in AI answers: per-brand rankings plus a co-mention graph of which brands the models name together. Its requestId can be passed to cite42_recommendations when the user asks for improvement advice. Priced per AI surface queried. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Find which sources a model's web search surfaces for a query. Aggregates cited URLs across models with per-model counts; optionally checks whether a specific URL is cited. Measures the retrieval corpus behind a prompt — which domains own your category in AI search, and where your content is missing — not the citation links a consumer chat UI renders for a logged-in user. Its requestId can be passed to cite42_recommendations when the user asks for improvement advice. Priced per AI surface queried. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Score how each AI model talks about a brand for a query: a positive/neutral/negative split per model with the verbatim phrases driving the tone, plus an aggregate across models. Its requestId can be passed to cite42_recommendations when the user asks for improvement advice. Priced per AI surface queried. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Page-level AI visibility recommendations, for when the user asks how to improve a page. With a saved result (requestId, trackerRunId or evidence) it reports on one measured prompt, charged only when the report includes page-comparison advice backed by quotes from inspected pages. Without one: url alone runs a free technical check of the page (robots.txt crawler access, indexing, rendering) and returns suggested buyer questions; url with query first runs a citations check, priced like cite42_citations, then the report. Prices are in cite42_pricing. Fetches the page, its robots.txt and up to two pages the AI surfaces cited, as returned HTML without JavaScript. No site-wide crawl, keyword advice or tracker activation. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Classic keyword data for a seed term. Omit ideas when the user only needs that seed's monthly search volume, CPC, or competition. Set ideas:true only when the user asks for related, alternative, or long-tail suggestions from provider candidates. Not a multi-model AI-search query. The reply echoes requestedKeyword and carries status "exact" or "no_data"; when the seed has no search volume, any related term that does appears under alternatives — never treat an alternative's metrics as the requested keyword's. Billed by outcome: cheapest when the seed has no search volume, more when it has metrics, most with ideas:true. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Check search volume, CPC, and competition for two to 50 distinct seed keywords in one request. No related ideas. Billed by outcome. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Google Trends interest-over-time, related and rising queries, and a rising/falling/stable label for a term. A flat-priced data tool, not an AI-model query. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Discover relevant Reddit discussions with Google Search and read up to three thread pages through Gemini URL context. Returns Gemini-read titles, authors, post excerpts, relative ages, available scores/comment counts and sampled human comments, plus cited model summaries. Check coverage and warnings: pages may be cached, extraction is not independently verified, and exact dates, growth and quote-based insights are unavailable. risingThreads is a deprecated alias of relevantThreads. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
YouTube trend data for rising videos, creator angles, title patterns, channel examples, and video-market opportunities around a topic. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Run the content-opportunities workflow: fans out across AI search, SEO keywords, trends, Reddit, YouTube, and citations and returns the aggregated data in one response. Billed for the steps that succeed, at per-surface rates. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.

Run the AI-prompt-map workflow: research for a list of buyer prompts worth tracking, from AI search, SEO demand, trends, citations, Reddit, and YouTube data. It returns evidence and a suggested prompt, not a finished list; prompts written from it can be tracked with cite42_tracker_create. Billed for the steps that succeed, at per-surface rates. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Run the competitor-content workflow: AI rankings, head-to-head comparison, citations, keyword demand, and topic coverage, aggregated in one response. Billed for the steps that succeed, at per-surface rates. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free).

For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Run the content-brief workflow: research for a content brief from AI answers, citations, SEO keyword demand, trends, Reddit, and YouTube signals. It returns evidence and a suggested prompt; write the brief from it. Billed for the steps that succeed, at per-surface rates. Billed in USD (result field cite42Billing) to the user's prepaid Cite42 balance; exact prices from cite42_pricing (free). For plans over 20 calls or $5, estimate the cost and confirm with the user first.
Create a draft weekly or monthly tracker: one measurement — rankings, compare, citations, or sentiment — applied to a list of prompts, with the brand, competitors and AI surfaces set once for all of them. Prompt lists can come from cite42_map_ai_prompts research. Creation does not start recurring calls. Managing trackers and reading reports is free; each run bills one call per prompt at the per-surface rates.
Replace a tracker definition: name, cadence, measurement, prompts and configuration. Send the complete definition, not a partial patch — a tracker read returns this exact shape, so read it, change what you need, and send it back. An edit returns the tracker to draft so its new recurring cost can be confirmed. Managing trackers and reading reports is free; each run bills one call per prompt at the per-surface rates.
Activate or resume recurring weekly or monthly tool calls. maxCostMicroPerRun must equal the tracker's latest estimatedCostMicroPerRun; activation authorizes future billed calls until paused. The response includes the balance, the cost per run, and runsDryAt, the date the balance stops covering active trackers. When tracker emails are enabled, activation sends a setup summary and every completed run sends current results and suggested next steps, even when nothing changed. Activation is refused when the balance cannot cover the next run. Managing trackers and reading reports is free; each run bills one call per prompt at the per-surface rates.
Pause future recurring calls for a tracker while preserving its configuration and stored run history. Free.
Permanently delete a draft or paused tracker, including its saved configuration and run history. Active trackers must be paused first, and deletion is rejected while a run is queued or running. Financial usage and billing ledger records are retained. Free.
Queue one manual run using the tracker’s saved tool inputs. A repeated requestToken returns the same logical run. Managing trackers and reading reports is free; each run bills one call per prompt at the per-surface rates.
List the connected account’s trackers with status, cadence, tool configuration, cost estimate, accepted per-run maximum, and next/last run times. Free.
Read bounded stored run history for one tracker, including per-tool results, changes from the prior comparable observation, statuses, sampled times, and costs. Free.
