AI Agent Toolkit

Infrastructure for AI agents to participate in the real economy

AI agents can now understand complex tasks, make decisions, and plan actions. But they hit a wall when trying to execute real-world transactions, blocked by CAPTCHAs, payment forms, and fraud protection.

Crossmint’s Agent Toolkit provides APIs and infrastructure that let AI agents participate in the real economy. From making purchases to managing digital assets, we handle the complexity of economic interactions, by leveraging crypto rails.

Crossmint’s SDK has been designed specifically for AI agent developers. It’s available as REST APIs, JS and python SDKs, as well as exposed as tools on the main agentic frameworks: MCP, OpenAI Agent SDK, Langchain, ElizaOS, and more.

Key Characteristics

Built for AI devs

SDKs in Python, JS and REST, and sample code for the most popular agentic frameworks

Safe by design

All agent behaviors are auditable onchain. Agent actions can be constrained with cryptographic assurances.

Enterprise Grade

SOC2 compliant, with SLAs available. Trusted by tens of thousands of devs, from startups to F500.

How Does it Work?

The Agent Toolkit consists of four core components that work together to enable AI economic activity:

• Agent Wallets allow your agents to securely hold funds and transact with them. They can be operated by your autonomous agents, while remaining non-custodial and not requiring you to hold licenses.

• Headless Checkout API enables agents to buy anything onchain, without a need for browser automations, anti-captchas, or virtual credit cards. It supports over 1 million items, including the full Amazon catalog, Shopify, and more. Items can be purchased USDC or any other cryptocurrency, across all our supported chains.

• Minting APIs let you issue and verify cryptographic credentials that enable permissioned commerce and ensure regulatory compliance.

FAQs

Is this production ready?

Yes. Crossmint’s AI agent toolkit leverages the same infrastructure and APIs already being used by major brands like Mastercard, Red Bull, Diageo, Coinbase, Phantom, for tokenizing real-world assets and enabling programmatic transactions.

What can agents actually do?

Agents can hold and transfer funds, purchase tokenized assets, execute smart contract transactions, and manage digital credentials - all through simple API calls.
