SimConnectNG takes one request, sends it through the healthiest channel on the right network, moves to another channel if that one stumbles, and tells you the final state through the response and a signed webhook. You pay a flat fee per delivered sale: it is held on your wallet when a request starts and settled or released when it ends.

Everything is plain JSON over HTTPS, with amounts in naira. Every response has the same shape: `success`, `data`, `message` and `code`.

## Start here

- [Quickstart](/docs/quickstart): a test key, a test sale and a webhook, in a few minutes.
- [Integrate with a coding agent](/docs/agents): a prompt you can paste into your agent, and the files it should read.

## How it works

- [Test mode](/docs/concepts/test-mode): build against test keys that never touch live money.
- [Authentication](/docs/concepts/authentication): API keys, how to keep them safe and how to rotate them.
- [Idempotency](/docs/concepts/idempotency): repeat a request safely, never charge twice.
- [Wallet](/docs/concepts/wallet): holds, settlement and the ledger.
- [Webhooks](/docs/concepts/webhooks): events, signatures and retries.
- [Errors](/docs/concepts/errors): the error shape and every code.

## API reference

The base URL is `https://api.simconnectng.com/api/v1`. Every endpoint is listed under **API reference** in the menu, each with one request, one response and one error you can copy.

## For agents

Every page is also available as plain markdown: add `.md` to its address. The full index is at [/llms.txt](/llms.txt), and every page in one file is at [/llms-full.txt](/llms-full.txt).
