Coinbase has been launched X402 Bazaar For AI-agent-driven X402 Micropayments.
The catalog reveals a machine-readable index of services that accept PAY-per-Request USDC payments and is positioned as a discovery layer for agents and developers who integrate the X402 protocol.
Coinbase says that Bazaar is in early development, and today indexes the endpoints that settle through the hosted facilitator.
X402 RESLEASES THE HTTP 402 “Payment requires” status code and a repeat current current in which the client confirms a signed payment spayload.
The hosted facilitator of Coinbase verifies and arranges the payment, so sellers do not need a blockchain infrastructure and the company declares that it does not charge a facilitator costs for USDC based on USDC.
According to Coinbase documents, the current network support is USDC on Base Mainstet and Base Sepolia, with extra assets on the route map. See the X402 Overviewthe Facilitator Documentationand http 402 background on MDN.
The white paper frames the economy on confirmations of Subsecond and negligible gas. It compares “X402 (on the base)” with a 200 millisecond settlement path and nominal gas far below a ten thousandth of a dollar, contrasting map costs and batch control.
Bazaar’s List Endpoint returns structured JSON for each source, including accepted active, network, destination address and the required maximum quantity, expressed in the atomic units of the token.
The example shows one maxAmountRequired
From 200 for USDC on the base, equal to $ 0.000200 at 6-decimal precision, to illustrate the intended price of the granularity system for per call payments.
The function of the Base-Flashblocks 200-Millisecond prejudice adds to the implementation path that shorten the observed confirmation time for interactive apps.
As soon as the network slot is included, infrastructure providers report typical end-to-end recognitions closer to 300-500 ms, while the standard block time of the base remains two seconds.
For measured APIs, this Latency Budget can make Prakt Prakt Practical without humiliating the user experience. To see Base flash blocks and a provider explains Chain stack.
Under the hood, most current implementations depend on the authorization-based transfers of EIP-3009, with which a customer can sign an authorization that the Facilitator on-Chain submits.

Regulation opens the door for digital payment infrastructure
The policy background now tilts to clearer Stablecoin rules in the United States. The congress was adopted in July and the President de Genius Act, a federal framework for payment staboins, signed that full support for cash or short-term or short-term and permits and supervision.
The European markets in the crypto-assets regime already apply to e-money tokens and asset-referred to tokens. The European Benet Authority Has clarified that EXPENTEN must have the relevant authorization and have published technical standards, with transition dependence for some art spending but not for EMTs. That mix means that every EU-oriented X402 settlement in Fiat-poned tokens is ultimately dependent on EMT-Compliance and supervision.
Macro context around the demand shifts as a dollar-stablecoins scale. The market value has doubled in 18 months to nearly $ 280 billion, with projections that reach the trillions under supporting policy and the IMFs Finance & Development discussed How USD-Stunned Stablecoins can influence the question of the treasury and the primacy of dollar.
A simple reach illustrates how Bazaar could earn money as an agent workload if technical and regulatory documents apply.
With the help of the minimum point of the white paper as a reference, the prices between $ 0.001 and $ 0.01 per call over 100 to 1,000 listed end points and 100,000 to 10 million calls would call the daily gross payment volume of $ 100 to $ 1,000 to $ 1,000 to $ 1,000.
Settlement costs and facilitator costs are the most important variables, and Coinbase states that the facilitator adds zero costs to the base, so that nominal gas is left as a limitation.
The commerce tie-in is important for distribution. Coinbase and Shopify announced USDC payments based on SHOPIFY payments, and Base’s own communication describes Base as a fast, cheap network that is integrated with the checkout.
If the stores in the chain normalize in mainstream e-commerce, the Pay-Per-use pattern of X402 can extend from the human cash register to API consumption of machine-to-machine using the same Stablecoin rails.
There are still open questions, Bazaar currently mentions services that settle in the basic in USDC, and the FAQ of Coinbase later points to more chains and assets.
The final acceptance depends on how quickly developers reported the price with the price of the price and whether latency at Flashblocks level translates into reliable, low variance payment confirmation on production scale.
For now, Bazaar’s Discovery API is Live, the facilitator is free on the basis of the base and the policy environment is sending the settlement of Stablecoin.
