Chainbase, the leading Hyperdata Network and Web3 data infrastructure provider, has officially integrated the x402 open payment protocol into its core platform.

Developed by Coinbase, x402 revives the HTTP “402 Payment Required” status code, enabling instant, stablecoin-based payments directly within data requests. This upgrade transforms how AI agents, developers, and applications access blockchain data — from fixed subscriptions to on-demand, pay-per-request transactions.

With x402, AI agents can autonomously pay for every API call or data sync — no accounts, no keys, no intermediaries. Developers gain flexible access to Chainbase’s multi-chain data through seamless micro-transactions, while the network benefits from real-time value capture tied to actual data usage.

The integration of x402 enhances Chainbase’s existing subscription plans (Free, Developer, Enterprise) with a new Pay-Per-Request model — designed for ultimate flexibility and automation.

“The integration of x402 brings Chainbase one step closer to a fully automated, agent-native data economy,” said the Chainbase team. “It turns data access into a direct value flow — open, programmable, and aligned with the AI era.”

The new Pay-Per-Request model complements existing subscription tiers and will roll out to select partners in November 2025, with public access to follow. More details please refer to: https://platform.chainbase.com/pricing

The first batch of Chainbase APIs and Data Sync services integrated with x402 will enter closed testing in November 2025 with selected developer and enterprise partners.

• Existing subscription users will continue to enjoy their current service tiers.

• Developers interested in Pay-Per-Request access can refer to the Chainbase documentation for setup and client integration guides coming soon.

Chainbase invites AI developers, Web3 protocols, and infrastructure builders to explore how x402 can empower the next generation of autonomous agents and data-driven applications.

The integration of x402 is more than a feature update — it’s a key step in building the economic infrastructure for AI-native agents.

By combining verifiable data, on-chain settlement, and autonomous access, Chainbase continues to push the frontier of how machines interact, transact, and learn.

Stay tuned for early-access announcements and developer documentation coming later this quarter.

Chainbase is building the Hyperdata Network for AI — a foundational layer for the DataFi era.

Built as a Hyperdata Network, Chainbase turns onchain signals into structured, verifiable, and AI-ready data that can be directly processed by AI models and decentralized applications. Its core stack includes:

• Manuscript: a programmable layer for building data assets;

• AVS layer: decentralized data execution and verification;

• $C Token: the native currency for AGI.

This structured data layer supports a new generation of crypto applications that are autonomous, composable, and economically aligned with their users and contributors.

To date, Chainbase has indexed over 200 blockchains, processed more than 500 billion data calls, and supports a community of more than 35,000 developers. Over 10,000 projects actively use Chainbase across a wide range of use cases, including MEV infrastructure, L2 explorers, agent protocols, and onchain analytics.

The founding team brings deep experience in blockchain infrastructure, data engineering, and protocol security. Chainbase is backed by top-tier investors and works closely with ecosystems across modular infrastructure, large language models, and onchain AI.

As the need for machine-readable and economically aligned data continues to grow, Chainbase provides the foundational layer for a programmable data economy—one where information moves freely between agents, protocols, and people.
