Everything agents need, in one place

From discovery to payment — a complete infrastructure for the agent-native economy.

Discover

Semantic search across thousands of MCP servers. Agents find the right tools by capability, not by name. Filter by protocol, trust score, and latency.

GET /api/v1/search
?q=pdf+generation&protocol=mcp

Authenticate

OAuth 2.0 built for agent-to-tool interactions. Agents authenticate autonomously — no human in the loop. Scoped permissions, token rotation, and audit logs.

Authorization: Bearer
imt_a1b2c3d4...x9y0z

Monetize

Usage-based billing for every tool call. Publishers earn from their MCP servers. Agents pay per invocation with automatic metering and invoicing.

POST /api/v1/billing/meter
{ "calls": 1, "cost": "$0.001" }

How it works

Three steps from zero to production

Register your MCP server

Publish your server with a structured capability manifest. Imagent auto-generates documentation, validates your schema, and makes it discoverable.

Agents discover and authenticate

Agents search by capability, evaluate trust scores, and authenticate via OAuth — all without human intervention. You define the permission scopes.

Get paid for every call

Set your pricing model — per-call, tiered, or freemium. Imagent meters usage, handles billing, and deposits earnings to your account.

Agent-native APIs,
not human-native ones

Every endpoint is designed for machine consumption. Structured responses, semantic errors, and built-in rate limiting. Your agent reads the spec, not a README.

Capability-based search with vector embeddings

OAuth 2.0 + agent identity tokens (AIT)

Automatic protocol adaptation (MCP ↔ A2A ↔ Function Calling)

Real-time usage metering and webhooks

agent.ts

import { ImagentClient } from "@imagent/sdk";

const client = new ImagentClient({
  apiKey: process.env.IMAGENT_KEY,
});

// 1. Discover tools by capability
const tools = await client.search({
  capability: "generate PDF from markdown",
  protocol: "mcp",
  minTrustScore: 0.8,
});

// 2. Authenticate and invoke
const result = await client.invoke({
  server: tools[0].id,
  method: "generate_pdf",
  params: { content: markdownBody },
  auth: { scope: "read:templates" },
});

// 3. Usage is metered automatically
console.log(result.usage);
// { calls: 1, cost: "$0.002", latency: "142ms" }
