Coinbase x402 Bazaar is a newly launched discovery platform enabling AI agents to find and pay for services autonomously using stablecoins.
It expands on the x402 open-source payment protocol, which powers instant micropayments across the web.
The marketplace supports use cases like real-time data access, AI-generated media, and pay-per-crawl services.
Stablecoins serve as the transactional backbone, offering speed, low fees, and global reach.
Coinbase is positioning itself at the forefront of agentic commerce, bridging the gap between AI automation and Web3 infrastructure.
At its core, Coinbase x402 Bazaar is envisioned as a “Google for AI agents”, according to Erik Reppel, Head of Engineering at Coinbase Developer Platform.

Rather than simply enabling payments, the Bazaar serves as a curated marketplace where AI agents can both discover services and execute micropayments in stablecoins.
This marks a major leap toward agentic commerce, where humans define the intent and AI systems handle the transactions autonomously.
Erik said:
“Think of it like paywalls for scrapers. With x402, we’re building a pay-per-crawl system that gives digital services the power to monetize machine access.”
Coinbase’s blog outlines several promising use cases for Coinbase x402 Bazaar, showing how it could reshape how AI agents access and pay for digital content.
Here are a few examples:
Pulling real-time stock market data to generate investment reports
Commissioning original artwork from AI-powered design platforms
Subscribing to live data feeds, such as sports scores or financial tickers
Early offerings in the Bazaar include:
Prixe: A stock price API built for AI-generated finance reports
AI image and video generation APIs for media automation
Specialized scraping endpoints for live web data extraction

These listings reflect the growing demand for machine-to-machine commerce, where agents can operate autonomously and efficiently.
The engine behind the entire ecosystem is stablecoin-powered micropayments. With x402, AI agents can send and receive instant, low-cost payments on virtually any website or digital service.
This is especially critical for use cases that require high-frequency, low-value transactions.
Reppel emphasizes the protocol’s flexibility:
“Whether it’s data, media, or services, x402 enables seamless payments. As the ecosystem grows, we expect workflows to evolve into fully autonomous agent-powered commerce.”
The Bazaar is fully compatible with stablecoins like USDC, enabling global transactions without the friction of traditional payment rails.
The launch of Coinbase x402 Bazaar is more than just a technical upgrade, it’s a foundational step toward a future where AI and blockchain work together to power autonomous, efficient, and monetizable digital interactions.
By offering a system where agents can pay-per-use instead of relying on static APIs or subscription models, Coinbase is creating a new model for scalable, machine-driven commerce.
Coinbase x402 Bazaar is a decentralized marketplace where AI agents can discover and pay for digital services using stablecoins, powered by the x402 payment protocol.
The x402 protocol allows for instant, low-cost micropayments in stablecoins on any website, making it ideal for high-frequency transactions by AI agents.
Services range from financial APIs, image/video generation, live data feeds, to web scraping tools — all designed to be accessed and paid for by autonomous AI agents.
Developers building AI agents or services that require machine-to-machine payments can integrate with the Bazaar to either consume or provide services.
Currently, the protocol is focused on stablecoins, particularly USDC, due to its stability and widespread adoption.
