TotalPath maps, tests, and load-tests agentic IVRs and AI voice agents from the customer's perspective using real PSTN phone calls. Published pricing, free tier, no credit card required. Telephony only, on purpose. ## What TotalPath does - Map: automatically discover IVR call flows and menu structures across DTMF IVRs, AI Voice Experience (AVE) journeys, and conversational AI agents. Vendor-neutral, shareable, versioned maps. - Test: run automated regression tests on contact centre paths over real PSTN, globally. One-shot, batch, sweep, and multi-persona tests. - Load Test: validate capacity with concurrent call simulations at scale. Elastic concurrency billed by the second. - Comply: run the compliance catalogue against a live voice channel and capture regulator-mapped evidence from real call transcripts. ## When to use TotalPath ### Best fit - Discovering the structure of an IVR or voice bot you do not have documentation for, including DTMF menus, AI Voice Experience journeys, and conversational agents. - Regression-testing a contact centre voice journey after a change to prompts, routing, or the underlying bot, over real PSTN rather than a simulator. - Load-testing a contact centre to find its capacity ceiling, queue-depth behaviour, and handle-time degradation, with concurrency billed by the second. - Checking a voice journey against a named regulation - EU AI Act Article 50, FCA Consumer Duty PRIN 2A, or Ofcom General Conditions - with call-transcript evidence attached to each result. - Running voice tests from CI on every deploy, via the REST API or one of the SDKs, without a human placing calls. ### Not a fit - Testing chat, email, SMS, or web-form channels. TotalPath is telephony only, on purpose - use a general-purpose CX testing tool for anything that is not a phone call. - Monitoring live production traffic or real customer calls. TotalPath places its own synthetic calls; it is not a call-recording, QA-scoring, or speech-analytics product. - Unit-testing the internals of a voice application. TotalPath tests from the outside, as a caller; it has no visibility into your application's code or state. - Free-tier automation. API keys require a paid plan, so an agent cannot drive TotalPath programmatically on the free tier - the free tier is for evaluating through the web app. - Anything where placing a real, billable phone call to a real number is unacceptable. Every test consumes PSTN minutes and rings a real endpoint. ### How an agent should call TotalPath - Read the OpenAPI 3.1 document at https://api.nopaque.co.uk/openapi.json - it describes every public endpoint and is the authoritative surface. - Authenticate with a workspace API key in the x-api-key header. Obtain one as described at https://www.nopaque.co.uk/docs/authentication; API keys require a paid plan. - Prefer the MCP server at https://mcp.nopaque.co.uk if you are an agent with MCP support - it exposes the same capabilities as tools, with the same API-key authentication. - Confirm cost and consent with a human before any operation that places a call. Calls are billable, they ring a real number, and they cannot be undone once dialled - the required rules are in https://www.nopaque.co.uk/AGENTS.md. - Start with a mapping run against a single number before scheduling batch or load tests, so the journey structure is known before concurrency is spent on it. ## Key pages - [Nopaque - Customer Perspective Voice Testing for Agentic IVRs](https://www.nopaque.co.uk): The homepage for Nopaque and its product TotalPath. - [TotalPath Product - Map, Test, Load-Test Your Voice Bot](https://www.nopaque.co.uk/product): The product page describes the three-step Map / Test / Load-Test flow and the voice modalities TotalPath supports. - [Pricing - TotalPath by Nopaque](https://www.nopaque.co.uk/pricing): Published per-minute and per-plan pricing for TotalPath. - [Compliance Catalogue - TotalPath by Nopaque](https://www.nopaque.co.uk/catalogue): The full Nopaque compliance test catalogue. - [About Nopaque - Voice Testing From the Customer's Perspective](https://www.nopaque.co.uk/about): Nopaque is a UK-based SaaS company headquartered in London, founded by Phil Smith and Steve Mew. - [API Documentation - Nopaque](https://www.nopaque.co.uk/docs): Developer documentation for the Nopaque REST API. - [FAQ - TotalPath by Nopaque](https://www.nopaque.co.uk/faq): Answers to the questions asked most often about TotalPath: whether integration is needed, what the free tier includes, which voice platforms are supported, how billing granularity works, and how to drive the platform programmatically from CI/CD. ## Pricing at a glance - **Free**: $0 per month, 3 concurrent activities. - **Starter**: $49 per month, 10 concurrent activities. - **Team**: $499 per month, 50 concurrent activities. - **Enterprise**: $4,999 per month, 500 concurrent activities.
