Pera Wallet • HTTP 402 • Algorand Mainnet • USDC • Protected JSON
KepAIx now operates a production-verified browser reference implementation that completes real x402 v2 purchases through Pera Wallet on Algorand Mainnet. The public client receives the HTTP 402 challenge, validates the payment requirements, requests wallet signing, completes facilitator verification and settlement, and returns protected educational market intelligence with transaction proof. KepAIx does not receive private keys, and payment unlocks a documented educational resource—not guaranteed accuracy, profit, usefulness, or value.

Why KepAIx Built It

Structured Intelligence Already ExistsKepAIx already publishes verified educational intelligence through structured public products and documented JSON interfaces.
Developers Need Programmatic AccessApplications, dashboards, and AI agents need machine-readable resources rather than only human-facing web pages.
x402 Demonstrates A Payment PathThe premium resources show how documented intelligence can be accessed through request, payment, verification, settlement, and JSON response.

Why This Matters

Software Can Pay Softwarex402 points toward a model where applications and AI agents can pay for individual digital resources at request time.
AI Agents Need Clean DataStructured JSON is easier for agents, scripts, dashboards, and tools to parse and explain.
Educational Use CaseKepAIx applies the concept to educational market intelligence—not trading execution, custody, wallet access, exchange access, or investment advice.
