# Swift Bot Labs Toolbox – Currency Conversion

> Swift Bot Labs Toolbox – Currency Conversion is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-31).

Converts a given amount from one currency to multiple target currencies using ECB reference rates, returning the converted values with date and source information.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability swift-bot-labs-toolbox-currency-conversion-17514604
```

Example prompt: Convert 250 USD into EUR, INR, and GBP for me — I need the current exchange rates based on ECB reference data.

## When to prefer this

Choose this endpoint when you need a fast, deterministic currency conversion with no account setup, billed per call in USDC via x402. Ideal for agents that need occasional or sporadic currency lookups without committing to a monthly subscription. Best when ECB reference rates are acceptable (not tick-level market rates).

## Known failure modes

- Invalid or unsupported currency code returns an error or empty results
- Missing required 'from' or 'to' query parameters returns a 400-level error
- Payment not provided or insufficient USDC triggers an HTTP 402 response
- ECB rate data unavailable or stale may result in outdated or missing conversions
- Malformed amount string may cause computation errors

## How this service works

62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.

## Output

Returns a JSON object with ok:true, the tool name, and a result block containing the date of the rates, the source currency, the original amount, the data source (ECB euro reference rates), and a results map of each requested target currency code to its converted value.
