# Number Base Converter - BigInt-Exact, Bases 2-36 — example

**Use case:** 

Radix conversion that never corrupts big values: BigInt throughout, so 2^64-1 converts exactly (floats fail past 2^53). Bases 2-36, 0x/0o/0b prefixes just work, negatives get 8/16/32/64-bit two's-complement views, bit/byte lengths included. $0.0004 per conversion; invalid digits never charged.

## Input

```json
{
  "value": "deadbeef",
  "fromBase": 10,
  "toBase": 16,
  "items": []
}
```

## 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.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **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).
