Freemium

Communication API that gives an AI agent a real phone number with voice, SMS and native iMessage on one line, provisioned in seconds.

Key features

  • Agent Phone Numbers on Demand: Real US, Canadian and international numbers are provisioned through a single API call, giving an agent its own phone identity in seconds.
  • Native iMessage with Fallback: Agents send blue-bubble iMessage from their own number, including inbound and cold outbound, with automatic RCS and SMS fallback.
  • Autonomous Outbound Calls: A call is placed with a plain-language instruction and constraints - what to ask, what to book, what price ceiling to hold - and runs on its own with real-time transcription and TTS replies.
  • Unified Multi-Channel Webhook: One webhook receives voice, SMS and iMessage events in the same format, so there is no per-channel plumbing to maintain.
  • MCP Server and Prompt Setup: Dial works out of the box as an MCP server with Claude Code, Cursor, Windsurf and Grok, and a single pasted prompt lets an agent complete the whole setup itself.
  • Self-Hosted or Managed Voice: Voice can run against your own LLM over WebSocket at a lower per-minute rate, or end to end on Dial's hosted model.
  • SDKs and REST API: Node.js and Python SDKs plus a LangChain integration and a direct REST API cover code-first integration paths.
  • Compliance Certifications: GDPR, CCPA, SOC 2 and HIPAA credentials are in place for security reviews.

Best for

  • Agent Errand Calls: Sending an agent to call a vendor, get a quote and book the earliest slot only if it stays under a stated budget, then reading the transcript afterward.
  • Customer Support Lines: Giving an AI support agent an inbound number that handles voice and text on the same line with transcripts routed to your systems.
  • Existing Chat Agents: Adding a real phone number to agents already running in WhatsApp, Telegram or a setup wizard, so SMS and voice work without building a telecom layer.
  • Autonomous Company Operations: Giving agent-run businesses a real phone identity so they can be reached and can transact by phone.
  • Verification and Notifications: Two-way SMS through the same number for confirmations, reminders and inbound replies routed to a webhook.
  • Prototyping by Prompt: Having a coding agent stand up a working phone number and place a test call within a minute, before writing any integration code.

Opper AI

Opper AI

Paid

EU-hosted AI gateway offering access to 300+ AI models through one OpenAI SDK-compatible, GDPR-compliant API.

Key features

  • Unified Model Gateway: One API and one key that routes calls to 300+ text, image, voice and video models across 30+ providers.
  • OpenAI SDK Compatibility: Drop-in base URL means existing OpenAI SDK code works unchanged against any model on the gateway.
  • EU Data Residency: Inference is hosted in the EU with a single sub-processor, so adding new models never triggers DPA amendments.
  • Intelligent Routing & Fallbacks: Per-request or org-level model selection with automatic fallback lists for zero-downtime model swaps.
  • Control Plane Guardrails: Optional Observe/Route/Steer/Guard/Comply modules add tracing, PII masking, content filtering and budget caps.
  • Agent CLI & Skills: Launch Claude Code, Codex, OpenCode and other agents against any Opper-hosted model or install auto-configuring skills.

Best for

  • GDPR-Compliant AI Products: European SaaS teams route all model calls through one EU sub-processor to keep customer data on-continent.
  • Multi-Model Experimentation: Product teams A/B test frontier and open models without changing SDKs or juggling many provider keys.
  • Cost & Latency Optimization: Ops teams use routing and fallbacks to prefer cheaper or faster providers per region while maintaining reliability.
  • Enterprise AI Governance: Compliance leads enforce model allowlists, PII masking, retention controls and budget caps across all agent traffic.
  • Agent Orchestration: Developers run coding and autonomous agents against a swappable backend model, with span-level tracing for debugging.
