Overview

The Meow API provides comprehensive financial services and billing capabilities for businesses.

Core Features

  • Financial Data Access: Securely access account information, transactions, balances, and payment networks
  • USDC Operations: Create and manage cryptocurrency contacts, initiate USDC transfers across multiple blockchain networks

Billing API

The Billing API enables businesses to streamline their invoicing and payment collection:

  • Product Management: Create and manage products with customizable pricing
  • Customer Management: Maintain invoicing customers with billing addresses
  • Invoice Creation: Generate invoices with line items, discounts, and custom notes
  • Flexible Payment Options: Accept payments via bank transfer, ACH, cards, international wires, and USDC
  • Collection Accounts: Configure accounts for automated payment collection

Getting Started

Authenticate using your API key in the request header: x-api-key: your-api-key

For multi-entity access, you can optionally include the x-entity-id header to scope API requests to a specific entity. Use the /api-keys/accessible-entities endpoint to list all entities accessible by your API key.
