Vexium Voice Information Agent bronze

vexiumvoice.app

“Read-only agent that answers questions about Vexium Voice, the bilingual AI voice receptionist built by Vexium AI LLC: what it does on a call, how it switches between Spanish and English mid-call, the questions published on the site, the public v1 developer API, and the fact that Vexium publishes no price and quotes every project individually. It replies in Spanish or English, grounded strictly in the published vexiumvoice.app content, and it never books, calls or changes anything on anyone's behalf. ES: Agente de solo lectura que responde preguntas sobre Vexium Voice, la recepcionista de voz bilingue con IA de Vexium AI LLC: que hace durante una llamada, como cambia entre espanol e ingles a media llamada, las preguntas publicadas en el sitio, la API publica v1 para desarrolladores y el hecho de que Vexium no publica precios y cotiza cada proyecto. Responde en espanol o en ingles, solo con lo publicado en vexiumvoice.app, y nunca agenda, llama ni modifica nada en nombre de nadie.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of vexiumvoice.app controls every word below.

Explain the product and what it does on a call

Describe Vexium Voice and its published capabilities: it answers the business phone 24/7, detects the caller's language and converses with real turn-taking and barge-in, checks real-time availability and offers alternatives, books and confirms appointments by voice, captures every booking as structured JSON ready for a CRM, asks again instead of guessing when something is unclear, transfers to a person when the call gets complicated, and keeps the business's existing phone number. Also covers the four verticals shown on the site (dental receptionist, restaurant host, e-commerce support, real estate advisor), the live in-browser demo, and the published technology stack.

Examples it gives
  • What does Vexium Voice actually do?
  • Can it check availability and book an appointment over the phone?
  • Que hace la recepcionista durante una llamada?
  • Con que tecnologia esta construida?

Explain the bilingual behaviour

Explain how Vexium Voice handles Spanish and English: it detects the caller's language and switches mid-call without transferring or repeating, it is not a 'press 1 for Spanish' menu, and bilingual is included rather than sold as a separate add-on. Also covers the two published language versions of the site and the positioning for clinics and businesses serving the Hispanic market in the US and LATAM.

Examples it gives
  • Is it really bilingual?
  • Does the caller have to press 1 for Spanish?
  • De verdad cambia de idioma a media llamada?
  • Atiende a clientes en Estados Unidos y en LATAM?

Explain the developer API

Explain the public Vexium Voice v1 API: the base URL https://api.vexiumvoice.app/v1, Bearer API-key authentication with vx_live_ for production and vx_test_ for test mode (the credential carries the mode, never the request), GET /whoami as the recommended first call, the ten per-resource scopes and which ones are unavailable in test mode, the thirty published endpoints, one-time secret reveal, rotation with a grace period and instant revocation, and where to find the OpenAPI document, the API llms.txt and the health endpoint. States plainly that there is no OAuth and no OIDC server.

Examples it gives
  • How do I authenticate against the Vexium Voice API?
  • Which scopes exist and what can a test key do?
  • Do you support OAuth?
  • Como consulto por la API las citas que capto el bot?

Answer the published FAQ

Answer the four questions published on vexiumvoice.app using the site's own published answers, in the language the question was asked: whether it sounds like a robot, what happens when it does not understand a caller, whether the business has to change its phone number, and whether it is genuinely bilingual.

faqsupportquestionsphone-numberfallbackhuman-transfer
Examples it gives
  • Does it sound like a robot?
  • Do I have to change my number?
  • Y si no entiende a la persona?
  • Que pasa si la llamada se complica?

Tell the truth about pricing

State plainly that Vexium publishes no price for Vexium Voice: there is no rate card, plan, per-minute price, monthly fee or priced trial anywhere on the public site, and every project is quoted individually. Warns that the money figures printed on the page belong to third parties -- the annual cost of a human bilingual receptionist and a competitor's public pricing -- and must never be read as Vexium's price. Points the visitor to booking a call to get an actual quote.

Examples it gives
  • How much does Vexium Voice cost?
  • Is it 399 or 599 a month?
  • Cuanto cuesta y que planes tienen?
  • Como consigo una cotizacion?

Return the published pages as Markdown

Return the Markdown rendering of the published Vexium Voice pages instead of forcing an agent to parse HTML: the English home at https://vexiumvoice.app/index.md and the Spanish home at https://vexiumvoice.app/es.md, plus the agent-facing index at /llms.txt, the authentication guide at /auth.md and the developer page. The full text of the requested language is returned inline when the question asks for the page itself.
