Consuming APIs

Find APIs on the marketplace, subscribe, integrate into your application, and monitor usage.

Discover APIs

Browse the marketplace at platform.wontopos.com/marketplace or search via the API:

GET /v1/marketplace/apis
const apis = await client.marketplace.list({
  category: "payments",
  search: "global payments",
  limit: 20,
});

Review and compare

Each API listing includes:

  • Interactive documentation and playground
  • Code examples in multiple languages
  • Pricing tiers and rate limits
  • SLA and uptime history
  • User ratings and reviews

Subscribe

POST /v1/subscriptions
const subscription = await client.subscriptions.create({
  apiId: "api_abc123",
  plan: "pro",
});

Instant activation

Subscriptions are activated immediately. You can start making API calls right away.

Integrate

Once subscribed, use your API key to call the subscribed API through the Wontopos gateway:

curl https://api.wontopos.com/v1/proxy/api_abc123/payments 
  -H "Authorization: Bearer $WONTOPOS_API_KEY"

Monitor usage

Track requests, latency, and errors in the Dashboard or via the Usage API:

const usage = await client.usage.get({
  apiId: "api_abc123",
  from: "2026-03-01",
  to: "2026-03-30",
});

console.log(`${usage.totalRequests} requests, avg ${usage.avgLatencyMs}ms`);
