Monid raises $7.7 million to plug AI agents into pay-per-use tools

What Monid Does

Monid is a platform that enables AI agents to tap into a single marketplace, allowing them to use pay-per-use tools and APIs without the need for multiple vendor accounts. The company's workflow is divided into three steps: discover, inspect, and run. Agents can search for tools, inspect their features, and execute calls without the need for separate subscriptions.

Pricing and Revenue Model

Monid's pricing starts at $0.0013 per call, with a 10% platform fee added on top of provider rates. This fee is how Monid generates revenue. The company has also open-sourced its engine, built on Deno 2 and TypeScript, under the MIT license.

Why the API Tax Matters

Monid is addressing the 'API tax' problem that developers face when using new capabilities. Each new capability usually requires another account, API key, and subscription. Monid's per-call billing model reduces this complexity and allows agents to pay for only what they use.

Impact on the Agent Economy

Monid's growth suggests that providers are willing to participate in the platform. The company's open-source engine is also a strategic hedge, building developer trust and community contributions. Monid's 10% platform fee is the business model, and its viability depends on volume.

Additional Details

Monid launched in April 2026 with approximately 200 tools. By September 2026, its catalog had grown to over 1,700 endpoints, sourced from 55 to 72 providers. The company has processed over 4 million agent transactions and has received a $2.1 million pre-seed from 1984 Ventures and Llama Ventures.

Monid's Future Plans

Monid plans to use the $7.7 million raised to scale its marketplace and infrastructure. The company is committed to reducing the 'API tax' and making it easier for developers to use pay-per-use tools and APIs for their AI agents.
