KepAIx Integration
Request. Inspect 402. Pay. Receive Protected JSON.
Start with a verified KepAIx premium endpoint, inspect its live machine-readable payment requirements, complete an Algorand Mainnet USDC payment, and receive structured educational intelligence. The fastest human-operated path uses the live Browser Marketplace, while autonomous clients can implement the same x402 flow programmatically.
KepAIx is educational only. Payment unlocks a documented resource and does not guarantee accuracy, value, profit, certainty, or future outcomes.
The Complete Flow
Five Steps From Discovery To Protected JSON
The protocol is simple: choose a verified resource, request it, inspect the HTTP 402 response, complete the listed payment, and validate the returned settlement evidence and JSON.

Two Verified Premium Resources
Both products use HTTP 402 and x402 v2. Always inspect the live payment requirements returned by the endpoint instead of permanently hard-coding terms into production clients.
Atlas Premium Intelligence
Broader structured educational synthesis of verified KepAIx intelligence. Public response schema version 0.1.0.
https://kepaix.com/api/x402-atlas.php
Inspect HTTP 402 — Opens in New Window
Current verified asset: USDC on Algorand Mainnet, ASA 31566704. Payment terms can evolve, so production integrations should always trust the live HTTP 402 requirements returned by the selected endpoint.
Fastest Human Path
Use The Live Browser Marketplace
The Browser Marketplace is the easiest production reference path for a person. It lets you complete the full flow without first writing a client.
What You Do
Select Market Regime or Atlas, connect Pera Wallet, request the resource, review the listed USDC price, approve the payment, and receive protected JSON.
Open Browser MarketplaceWhat It Demonstrates
Product selection, wallet connection, HTTP 402 discovery, payment approval, Algorand settlement, payment verification, and protected resource delivery through one shared purchase engine.
Developer Request
Start By Inspecting HTTP 402
An unpaid request is supposed to return HTTP 402. In an x402 workflow, that is the protocol response that tells the client how to continue.
Initial Atlas Request
curl -i \ -H "Accept: application/json" \ https://kepaix.com/api/x402-atlas.php
Expected Result
HTTP 402 Payment Required with machine-readable payment metadata describing the gated resource and its current payment requirements.
HTTP 402
Simplified JavaScript Inspection
const response = await fetch(
"https://kepaix.com/api/x402-atlas.php",
{ headers: { Accept: "application/json" } }
);
if (response.status !== 402) {
throw new Error(`Expected HTTP 402, received ${response.status}`);
}
const paymentRequired =
response.headers.get("PAYMENT-REQUIRED");
if (!paymentRequired) {
throw new Error("Missing PAYMENT-REQUIRED header");
}
// Decode and validate the live payment requirements
// before constructing any payment payload.
Programmatic Flow
The Verified x402 Client Sequence
The current KepAIx Atlas test client follows this sequence. Public examples should never include private keys, local environment values, push secrets, or protected server logic.

Protected Response
What The Premium Resource Provides
Payment unlocks the selected documented educational resource. It does not guarantee that every optional field is populated in every response.
Market Regime Intelligence
Focused premium regime context designed as the verified paid counterpart to the free Market Regime API.
Atlas Premium Intelligence
May include executive summary, market environment, cross-system synthesis, evidence, contradictions, confidence, risk context, historical context, educational interpretation, limitations, disclaimer, and metadata.
Defensive Integration
Validate Before You Trust The Response
Machine-payable access does not remove the need for defensive integration. Validate both the payment protocol and the returned educational data.
HTTP StatusConfirm the expected unpaid, paid, and error responses.
Content TypeConfirm the response is the expected machine-readable format.
x402 VersionValidate the protocol contract supported by the client.
Resource IdentityConfirm the endpoint and product match the intended request.
NetworkValidate the network declared by the live payment requirements.
Asset And AmountVerify the asset identifier and exact requested amount.
RecipientValidate the live payment recipient before authorization.
SettlementConfirm the payment response indicates successful verification and settlement.
SchemaValidate the response version or Atlas schema before use.
FreshnessInspect timestamps and freshness indicators.
ConfidenceDo not convert confidence into certainty.
LimitsPreserve limitations, disclaimers, and unavailable-data conditions.

Quick Start FAQ
What Builders Should Know
These answers are written for developers, autonomous clients, technical reviewers, and x402 challenge judges.
What is the fastest way to test KepAIx?Open the Browser Marketplace, select a product, connect Pera Wallet, approve the listed payment, and receive protected JSON.
Is HTTP 402 an error?For an unpaid x402 request, HTTP 402 is the expected protocol response that tells the client how to continue.
Should I hard-code the payment terms?No. Read and validate the live requirements returned by the selected endpoint.
Does payment guarantee accuracy?No. Payment unlocks a documented educational resource and does not guarantee accuracy, certainty, value, or profit.
Can an AI agent use the same flow?Yes. An autonomous client can inspect the HTTP 402 requirements, construct the supported payment payload, retry the request, and validate the response.
Is KepAIx financial advice?No. KepAIx provides educational market intelligence only and does not provide financial, investment, trading, legal, or tax advice.
