Recent verified changes in this category

This ranking recomputes from verified capability research rather than opinion, so it moves when the underlying evidence moves. These are the most recent sourced change log entries for the vendors ranked highest here, newest first, one per vendor.

  1. Retell AI pricing / packaging

    Medium impact

    Legacy monthly billing at Retell has ended, and every remaining self serve workspace moved to prepaid credits, starting any workspace that had not switched on its own at a $0 balance. Calls and chats now draw down credits and stop at zero unless auto recharge is on, while phone numbers and some add ons still bill monthly and enterprise accounts stay on invoices.

  2. Vapi mcp / tool calling / api

    High impact

    Agent Phone, now in public beta from Vapi, is a remote MCP server that lets assistants such as Claude Code and Cursor place phone calls for a user. After a one time approval in the browser, the agent dials, works through phone menus, waits on hold, talks to the person and reports back, with no telephony setup.

    September 30, 2026 · Verified · All Vapi changes

  3. Cognigy mcp / tool calling / api

    Medium impact

    Cognigy 2026.20 added an experimental A2A Server Endpoint that exposes a Cognigy.AI flow to outside agents over the Agent2Agent protocol, with an agent card, skills, streaming, multi turn conversations and long running tasks. A new A2A Agent Node works the other way, letting a Cognigy AI agent call a remote A2A agent as a tool.

  4. ElevenAgents agent capability

    High impact

    ElevenLabs released Eleven v4 and Eleven v4 Turbo, a new text to speech family it trained itself, with more expressive speech and better voice cloning across more than 90 languages. The Turbo model is the real time version for agents, with a stated median latency of about 100 ms, and both are available in ElevenAgents now.

    September 28, 2026 · Verified · All ElevenAgents changes

  5. Smallest AI mcp / tool calling / api

    Medium impact

    Smallest AI added POST /waves/v1/auth/token so servers can issue temporary credentials for browser and mobile speech clients while retaining the API key. Tokens last 30 to 900 seconds, defaulting to 300, and authorize supported speech synthesis, transcription, speech to speech, and voice listing routes. They cannot authorize voice cloning, LLM chat completions, analytics, or further token creation; usage remains billed to the issuing key.

How this ranking works. Each vendor's Agentic Index coverage score is the sum of its verified feature scores across the 14 buyer facing capabilities in the Agentic Index taxonomy, researched from public sources. Full support counts 1.0, partial support counts 0.5, and ties are broken alphabetically. A low score means less documented coverage in public materials, not a definitive absence of capability. The buyer need block above is computed from the same scores, taking the subset of criteria each need depends on. No vendor pays for placement.
