Anima vs Proxy.ai: Communication Layer vs Intent Policies

Infrastructure for Agent Identity#

Building agents that can interact with the real world requires more than just a LLM and a tool-calling loop. It requires a stable, verifiable identity that legacy systems can recognize. Proxy.ai and Anima take fundamentally different approaches to how that identity is constructed and used.

Intent Policies vs Communication Layer#

Proxy.ai focuses on intent-based policy enforcement for agents. Their system runs your agent's actions through a proprietary policy engine that determines if a transaction fits a predefined "intent."

Anima treats communication and identity as the missing primitive. We prioritize the channels every legacy web service expects from a real user — email, phone, SMS, and voice — under a single agent identity, with server-side compliance gates and a unified audit log.

Beyond the Policy Engine#

The biggest differentiator is the depth of the identity. Proxy.ai provides intent-based control, but an agent often needs more than that to complete a task. It needs to receive 2FA codes, store merchant passwords, and correspond with support teams via email.

Anima provides a complete identity stack:

1. Deterministic Email: Dedicated MX/SMTP infrastructure for every agent.
2. Phone & Voice: Real numbers for SMS verification and automated voice interactions, behind a server-side TCPA consent gate.
3. Identity Vault: Secure, encrypted storage for merchant credentials, API keys, and PII.

Code Comparison: Provisioning an Identity#

Using the Anima SDK, you can provision a complete agent identity in a single call.

import { Anima } from '@anima-labs/sdk';
 
const anima = new Anima({ apiKey: process.env.ANIMA_API_KEY! });
 
const agent = await anima.agents.create({
  orgId: process.env.ANIMA_ORG_ID!,
  name: "Procurement Agent 01",
  slug: "procurement-01"
});
 
// The inbox comes with the agent — no separate provisioning step
console.log(agent.emailIdentities[0]?.email);
// procurement-01@agents.useanima.sh
 
// A number is one call, on the same agent
const phone = await anima.phones.provision({
  agentId: agent.id,
  countryCode: "US",
  capabilities: ["voice", "sms"]
});

Proxy.ai's proprietary approach often requires mapping specific LLM outputs to their internal intent objects. Anima gives you direct access to the underlying communication channels through a unified API.

Summary of Differences#

If you need intent-based policy enforcement for an agent, Proxy.ai is a solid choice. If you need a comprehensive identity that includes communication, voice compliance, and credential storage, Anima is the standard.
