DialNexa

DialNexa is a Voice AI agents platform for sales calls, lead qualification, follow-ups, meeting booking, collections and support workflows, with a strong focus on Indian-market multilingual calling (English, Hindi, Hinglish, Marathi, Kannada, Gujarati, Tamil, Telugu, Bengali and mixed-language calls). The public contract is an OpenAPI 3.0 document of 43 paths and 56 operations served from api.dialnexa.com with bearer authentication. DialNexa publishes an RFC 9727 api-catalog as a proper application/linkset+json document, two llms.txt files (a site index and a 90KB documentation index), an auth.md written explicitly for AI agents and automation systems describing how API keys are provisioned, an official remote MCP server at api.dialnexa.com/v1/mcp (OAuth 2.1 with PKCE, 97 documented tools), and a provider-published Agent Skill served from /.well-known/agent-skills/.

DialNexa publishes 13 APIs on the APIs.io network, including Agents API, Batch Calls API, Calls API, and 10 more. Tagged areas include Voice AI, AI Agents, Telephony, Lead Qualification, and Multilingual.

The DialNexa catalog on APIs.io includes 1 event-driven AsyncAPI specification.

DialNexa’s developer surface includes authentication, sandbox, documentation, API reference, getting-started guide, engineering blog, signup flow, and 27 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/dialnexa: open an issue to ask a question, or submit a pull request to add artifacts.

  note: 'Submitted via apis.io/add on 2026-08-21 (twice, as "DialNexa" and "DialNexa | Voice AI Agents Platform" — one provider,
    two records at the gate). The submitted APIs.json URL, https://dialnexa.com/apis.json, returns 404; that is a bad pointer
    in the submission, not an absent surface. A NOTE ON HOW THIS WAS FOUND, because the first pass got it wrong. Probing guessed
    paths (/openapi.json, /developers, /api-docs) suggested DialNexa published nothing: /openapi.json 404s, and /developers
    and /api-docs both return HTTP 200 with the same ~14,930-byte SPA shell the site serves for any unknown path, including
    an invented control. Reading the provider''s own llms.txt instead produced the real locations, and they are all live:
    an application/linkset+json api-catalog, a 352KB OpenAPI under /docs/api-reference/, a 90KB documentation llms.txt, and
    an auth.md addressed to AI agents. Guessing paths on a soft-200 host produces a false negative; the provider''s own index
    is the authority.'
