Live x402 on Algorand Mainnet

KepAIx turns HTTP 402 into a paid AI market data layer.

KepAIx uses x402 on Algorand Mainnet to unlock educational AI-generated market regime data after a verified USDC payment. A client requests the endpoint, receives a payment requirement, signs payment, the facilitator verifies and settles, and KepAIx returns the paid JSON resource.

What It Demonstrates

A real paid API without accounts, subscriptions, or API keys.

The KepAIx x402 implementation demonstrates pay-per-request access to AI-generated educational market intelligence. The endpoint does not require a traditional login or subscription to return the paid resource. Instead, payment is handled at the HTTP layer using x402.

Paid Data

KepAIx charges for one-off access to an educational market regime JSON resource generated from the KepAIx Main Brain snapshot.

Agent-Ready Access

The API can be discovered and consumed programmatically, allowing compatible clients or agents to respond to HTTP 402 payment requirements.

Algorand Settlement

Payments settle on Algorand Mainnet using USDC ASA 31566704, taking advantage of fast settlement and low transaction costs.

Payment Flow

How the KepAIx x402 request works.

The endpoint follows the x402 pattern: unpaid requests receive HTTP 402, valid payments are verified and settled, and paid requests receive the protected JSON resource.

KepAIx does not take wallet custody, request seed phrases, manage private keys, connect to exchanges, or execute trades. The API returns educational information only.

Client requests endpointThe client calls the KepAIx market regime API.

Endpoint returns HTTP 402If no valid payment is present, the endpoint returns payment requirements.

Client signs paymentThe x402 client prepares and signs the Algorand USDC payment.

Why x402 Matters for KepAIx

x402 allows KepAIx to offer AI-generated data as a paid digital resource without forcing every user or agent into a traditional subscription model. This fits the future of agentic commerce, where software can discover, pay for, and consume information directly.

Why Algorand Matters

Algorand gives KepAIx a low-cost settlement layer for small, repeatable payments. That matters for pay-per-request APIs where each request may only cost a small amount but still needs reliable settlement.

KepAIx is building toward paid AI intelligence APIs.

The current x402 endpoint is the first live paid KepAIx API. Future endpoints may expand into additional educational risk scores, asset sentiment snapshots, portfolio context, AI learning metrics, and market regime history.
