Celo Opens Agent Payment Marketplace as Privy Adds XRPL Wallets and Tether Backs AIsa

Celo, Privy and Tether are building ways for AI agents to access paid services, hold funds and operate within spending limits.

An AI agent needs a funded wallet and spending rules before it can buy a data feed or call a paid software tool. Celo has opened a marketplace for per-request purchases. Privy and Ripple announced an XRPL wallet integration, while Tether invested in AIsa, which brings paid API access and business-set spending limits into one platform.

Each announcement addresses a different step in an agent’s purchase: finding a service, holding funds or controlling costs. Chainalysis supplies usage data from Base, where it counted x402 transactions, most of them small. The products are at different stages, so the transaction total should not be read as a count of paying customers.

Celo Opens buy Marketplace and Lets AI Agents Pay for More Than 700 Services

Celo Core Co. launched buy on October 13, giving AI agents a marketplace of more than 700 tools and APIs that they can pay for per request. The catalogue includes computing, web and blockchain data, and browser sessions. Agents can use USDC, USD₮ or USA₮ on Celo rather than requiring a separate subscription for each service.

In the Celo developers' launch announcement, a service responds to an agent's request with a price through HTTP 402. The agent signs a payment for that amount locally, the payment settles on Celo, and the service returns the result. Cencori, Chainstack and SQD are among the initial providers. Developers still need to fund the agent's wallet and decide which services it can call. For AI crypto services, per-request payment could replace separate accounts and API keys for each provider.

Privy and Ripple Bring Programmable XRPL Wallets to Payment Apps and AI Agents

Privy and Ripple announced on October 13 that developers will be able to create and manage XRP Ledger wallets through Privy's infrastructure. The integration is intended for payment apps and agentic commerce, with support for signing transactions involving XRP, RLUSD and other XRPL assets.

Privy's announcement says developers will be able to build server-side wallets and x402 payments without asking users to manage keys directly. Policy controls and gas sponsorship are described as further work, so they should not be presented as features already available. For an AI agent, a programmable wallet supplies an address and a transaction-signing route. Teams comparing crypto wallets still need to establish who authorizes each payment and how much the agent may spend.

Tether Backs AIsa to Give AI Agents Paid API Access With Spending Limits

Tether Capital announced an investment in AIsa on October 15. AIsa lets AI agents reach paid data, software and computing resources through one interface, with charges billed in fiat or stablecoins and spending limits set by the business. The investment amount was not disclosed.

The Tether announcement says AIsa offers access to more than 5,000 APIs, skills and models through one key. AIsa reports more than 250,000 agents and over 100 million transactions on its platform; those are company-reported figures, not a count of distinct paying businesses. The offering combines service discovery and payment, while the spending cap gives an operator a way to bound an agent's purchases. For suppliers of paid tools, it is another distribution route alongside conventional accounts and crypto payment gateways.

Chainalysis Counts 138 Million Base x402 Transactions and Finds Mostly Small Payments

Chainalysis reported this week that more than 138 million x402 transactions had occurred on Base by the end of its 2026 reporting period. The report examined a longer, 16-month window ending in September 2026 to understand the young protocol. More than 87% of the payments it analyzed fell between one-hundredth of a cent and ten cents.

The Chainalysis study also found payments to data and search APIs, code review, financial intelligence and model inference. Transaction count alone does not establish how many independent agents or customers paid, nor whether every transfer reflects lasting demand. It does show why per-call pricing attracts developers: small purchases can be settled through blockchain services that accept amounts conventional card fees would make impractical. The wallet-funding and repeat-use data in the report provide a better measure of continued activity than the headline transaction total alone.
