The problem with African infrastructure

Building in African markets means juggling dozens of APIs, managing multiple relationships, and dealing with inconsistent documentation.

Fragmented infrastructure

Every service requires its own integration, API keys, and documentation. What should take days takes months.

Inconsistent quality

Unreliable uptime, poor documentation, and varying API standards slow down your development cycle.

High integration costs

Each new market means new partnerships, compliance checks, and technical integrations that drain resources.

How Simpo works

Plug in once, access everything. We aggregate Africa's digital services into one beautiful, consistent API experience.

1

Get your API key

Sign up and get instant access to SIMPOโ€™s unified API gateway in seconds.

2

Integrate Once

Connect via our single endpoint to access, Fraud detection, payments, SMS, credit scoring, KYC, USSD, and more.

3

Scale Without Limits

Expand into new services and markets instantly โ€” no extra integrations, no added complexity

// Fraud detection: evaluate risk before charging
const risk = await simpo.fraud.evaluate({
userId: "cust_123",
amount: 25000,
currency: "UGX",
deviceFingerprint: fp,
ip: req.ip,
metadata: { channel: "web", mcc: "6012" }
});
if (risk.decision === "block") throw new Error("High risk transaction");
if (risk.decision === "review") queueManualReview(risk);
// proceed with payment only after passing checks
