Action Cost Start tracking a company (idempotent) counts against tracked-company limit (billing consequence) Create and track companies from LinkedIn URLs (bulk) counts against tracked-company limit ## Pricing, plan by plan US dollars, as Clearcue's pricing page shows them on 25 Oct 2026. Monthly and annual billing are shown apart. Free tier 14-day free trial, no credit card (live in-app sidebar '14 days left on Free trial' and register page 'Start your 14-day signal sprint', 2026-10-25; matches docs: 200 research credits, no CSV export, webhooks or CRM). On the live trial BOTH the External REST API ('API access is not enabled for your plan') and the Clearcue MCP ('requires an active paid plan') are locked. The marketing pricing page still says 7-day trial with unlimited leads; the live app wins. ### Starter [Price not verified](https://www.clearcue.ai/pricing) unlimited users, 7 active signals, Clearcue MCP (paid plan only, not on trial), CSV export, Slack notifications; no webhook, API, CRM sync or tracked accounts per pricing comparison table No API ### Pro [Price not verified](https://www.clearcue.ai/pricing) 25 active signals, company AI qualification, webhook, API access; no CRM sync or tracked accounts per pricing comparison table API included ### Scale [Price not verified](https://app.clearcue.ai/plans) 75 active signals, CRM integrations, API access (everything in Pro) API included ### Custom Custom quote unlimited active signals, 500+ tracked accounts, web research signals, warm intro paths, SSO, CRM sync, priority SLA, dedicated success manager API included ## Rate limits Per billing account, one-minute window, shared across every API key issued under that account; raisable on request. More on limitsLess X-RateLimit-Limit/Remaining/Reset (Reset = Unix epoch seconds) on authenticated responses; 429 adds Retry-After; 401/403 carry no rate-limit headers. Numeric limit not published. ## How to get an API key Clearcue uses API key. The steps below follow Clearcue's own docs. 1. Create a Clearcue account. API access starts on the Pro plan. 2. Settings → Integrations → API (org-owned key, shown once, revocable). MCP key is created under Settings → Integrations → MCP and is NOT interchangeable with the REST key. 3. Send it with every request: header `Authorization: Bearer ccapi_.` (REST); MCP uses OAuth 2.0 or a separate `clc_` key. 4. Make a first call: List companies with app filters. Keep the key in an environment variable, never in the command. ``` curl -X GET "https://api.tools.clearcue.ai/external-api/v1/companies" \ -H "Authorization: Bearer $CLEARCUE_API_KEY" ``` ## Where the docs live What Where Documentation [docs.clearcue.ai](https://docs.clearcue.ai) API reference `https://api.tools.clearcue.ai/external-api/v1/openapi.json` OpenAPI spec `https://api.tools.clearcue.ai/external-api/v1/openapi.json` llms.txt [docs.clearcue.ai/llms.txt](https://docs.clearcue.ai/llms.txt) Changelog [clearcue.ai/changelog](https://www.clearcue.ai/changelog) Base URL `https://api.tools.clearcue.ai/external-api/v1` MCP server `https://api.tools.clearcue.ai/mcp` ## Strengths and limits ### Where it fits - Pre-templated, AI-filtered high-intent signals such as Asking for Recommendations, Frustration Expression and Agency Search - Pushing every person in a saved List to a CRM/sequencer/Clay via webhook as soon as they match - Nightly incremental sync of signal evidence using the completeThrough watermark on insights endpoints - Agent-driven exports and signal setup from Claude/ChatGPT via MCP ### Where it falls short - Raw contact data or bulk list building; it is a signal engine, not a database - API use on Starter: API access is listed from Pro upward - Teams needing many concurrent watches: active-signal caps are 7 (Starter), 25 (Pro), 75 (Scale, in-app only) (source:; app.clearcue.ai/plans 2026-10-25) - Trying the API or MCP before paying: both are locked on the 14-day trial ### Worth knowing - Prices are in EUR, not USD - Scale plan (EUR 549/mo, EUR 439/mo annual, 75 signals, CRM integrations, API access) is live in-app and in llms.txt but hidden from the marketing pricing page. llms.txt also lists audience caps (1/5/15) that neither the pricing page nor the app shows (app.clearcue.ai/plans 2026-10-25) - Trial length conflicts: pricing page and llms.txt say 7 days unlimited leads; billing docs AND the live app say 14 days (200 research credits). Live app wins: 14 days. The trial has no REST API, no MCP, no CSV export, no webhooks - REST key (ccapi\_) and MCP key (clc\_) are different. A clc\_ key on REST returns 401 'Invalid API key', which looks like a bad key - REST also needs the org's 'API access enabled' flag, otherwise 403 8 moreShow fewer - Page-size param differs: pageSize on /companies and /people, limit (clamped 1-200) on insights (same file §3) - Insights are events: upsert on id, never append; the same id returns with more sources\[\] over time (same file §2) - POST /tracked-companies does not return usage, and whether a 409 is all-or-nothing is undocumented (same file) - Active-signal cap (7 / 25) is the real constraint; creating a signal on a full org needs a pause first and MCP has no delete - Qualification prompts must stay short (~60-150 words), use post content only, and follow ClearCue's 4-part format - Webhooks sync only from saved Lists, so build the List filter first - Webhook plan gate conflicts: docs say Starter or Pro; the pricing comparison table says Pro and up - Tracked companies (account tracking) is not self-serve: billing page shows 'Tracking isn't enabled for your account yet. Request access'; pricing table gives tracked accounts only on Custom (500+) ### Our take We create ClearCue signals for client campaigns through its MCP server, inside the client's own ClearCue organization. When we created a custom post signal through the MCP, two fields did not store as sent: the display name took the description text and the category "events" was saved as "other", so we read every signal back after creating it. The live MCP export tools also cap at 10,000 records, while the public docs say 100,000. ## Who should use it Use Clearcue for Pre-templated, AI-filtered high-intent signals such as Asking for Recommendations, Frustration Expression and Agency Search Look elsewhere for Raw contact data or bulk list building; it is a signal engine, not a database ## If Clearcue is not the answer Other Signals tools in this directory, each with its own review.
