## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## NUBAN Bank Resolver — Nigerian Account Numbers + African Bank Codes

Which bank does a Nigerian account number belong to? This actor answers that **offline and
instantly** using the official CBN NUBAN check-digit algorithm — plus a bank-codes directory
covering **8 African countries** (Nigeria, Kenya, Ghana, South Africa, Egypt, Morocco, Zambia,
Tanzania) with CBN codes, SWIFT/BIC and USSD codes.

### Operations

| Operation | Input | Output |
|---|---|---|
| `resolveAccounts` | 10-digit NUBAN number(s) | Possible Nigerian banks (algorithmic candidates) |
| `validateAccount` | account number + 3-digit bank code | Does the pair pass the CBN check-digit? |
| `listBanks` | country code (or empty = all) | Bank name, code, SWIFT/BIC, USSD, type |
| `resolvePhones` | Nigerian phone number(s) | Mobile network (MTN, Glo, Airtel, 9mobile) |

### Use cases

- **Fintech & payments** — pre-validate account/bank pairs before hitting a paid name-enquiry API;
  catch typo'd account numbers for free.
- **Fraud screening** — an account number that fails the check-digit for the claimed bank is a red flag.
- **Ops & reconciliation** — batch-classify account numbers in payout files by likely bank.
- **AI agents** — bank code, SWIFT and USSD lookups as a tool call.

### Honest note on `resolveAccounts`

NUBAN check-digits narrow 10-digit numbers to a *small set* of algorithmically-possible banks
(often 2–4 of Nigeria's 30+). Definitive single-bank resolution requires a live name-enquiry — the
algorithm can only tell you which banks are mathematically possible. `validateAccount` (known bank)
is deterministic.

### Output example

```json
{
  "operation": "resolveAccounts",
  "query": "0690000031",
  "valid": true,
  "result_name": "Access Bank",
  "result_code": "044",
  "swift_code": "ABNGNGLA",
  "ussd": "*901#",
  "detail": "possible bank (3 algorithmic matches)"
}
```

### Pricing

Pay per lookup result. No external API keys, no rate limits, no network dependency — results in
milliseconds.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "accountNumbers": [
        "0123456789"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("mansalabs/nuban-bank-resolver").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});
