Voidly

Voidly Pay is an open marketplace and payment rail designed specifically for AI agents to discover and pay for HTTP services. Addressing the limitations of traditional payment systems—which typically assume human interaction, persistent billing relationships, or wallet interfaces—Voidly Pay enables autonomous agents to transact using only a cryptographic identity and a budget. Every paid HTTP call is treated as an x402 transaction, where the protocol leverages HTTP 402 responses and signed quote headers to facilitate payments between agents and service providers.

The platform allows anyone to list a paid HTTP endpoint in about a minute using a browser-based signing flow that generates an Ed25519 keypair locally. Payments are settled in under 200 milliseconds via the x402 protocol, with every credit backed 1:1 by USDC held in a Sourcify-verified vault on the Base mainnet. The marketplace currently features 17 paid endpoints operated by Voidly, as well as additional third-party listings registered through a self-serve process. Endpoint offerings include generic agent utilities such as hash generation, timestamping, random byte creation, QR code generation, Wikipedia summaries, exchange rates, HTML-to-markdown conversion, and URL metadata extraction. Additional endpoints support document extraction, web scraping, country-pinned fetching through a network of probes, and various research services like shutdown risk forecasts, claim verification, incident summaries, agent discovery, and bulk exports.

The platform is accessible to any MCP-compatible agent client, with integration available through the @voidly/pay-mcp package. Installation can be performed via a simple configuration in the client’s MCP settings, and the first call mints and stores an Ed25519 keypair while providing 10 free starter credits through a faucet. Alternatively, users can claim a wallet directly in the browser without signup or installation. Receipts for transactions are Ed25519-signed and can be verified offline.

Voidly Pay operates as a two-sided marketplace, serving both service providers who wish to monetize HTTP endpoints and AI agents seeking reliable access to paid services. The system’s design focuses on fast settlement, cryptographic security, and ease of integration for autonomous agents.
