Tools

`convert_currency`

Convert an amount between any supported fiat or cryptocurrency pair.

Input:

{ "amount": 100, "from": "USD", "to": "INR" }

Output:

{
  "amount": 100,
  "from": "USD",
  "to": "INR",
  "result": 8312,
  "rate": 83.12,
  "inverseRate": 0.012031,
  "timestamp": "2026-02-14T12:00:00.000Z",
  "source": "exchangerate-api",
  "cached": false
}

Natural language works too:

{ "amount": 1, "from": "bitcoin", "to": "rupees" }

`batch_convert`

Convert an amount from one currency to multiple targets in a single call. More cost-effective than multiple individual conversions.

Input:

{ "amount": 1000, "from": "USD", "to": ["EUR", "GBP", "INR", "JPY", "BTC"] }

Output:

{
  "amount": 1000,
  "from": "USD",
  "conversions": [
    { "to": "EUR", "result": 920, "rate": 0.92, "inverseRate": 1.086957, "source": "exchangerate-api", "cached": false },
    { "to": "GBP", "result": 790, "rate": 0.79, "inverseRate": 1.265823, "source": "exchangerate-api", "cached": false },
    { "to": "INR", "result": 83120, "rate": 83.12, "inverseRate": 0.012031, "source": "exchangerate-api", "cached": false },
    { "to": "JPY", "result": 149500, "rate": 149.5, "inverseRate": 0.006689, "source": "exchangerate-api", "cached": false },
    { "to": "BTC", "result": 0.02, "rate": 0.00002, "inverseRate": 50000, "source": "coinbase", "cached": false }
  ],
  "timestamp": "2026-02-14T12:00:00.000Z"
}

Supports up to 50 targets per call. Duplicate and same-as-source currencies are automatically filtered.

`get_exchange_rates`

Get current exchange rates for a base currency against multiple targets.

Input:

{ "base": "USD" }

Returns rates for the top 20 currencies (USD, EUR, GBP, JPY, INR, AED, CAD, AUD, CHF, CNY, SGD, HKD, KRW, BRL, MXN, ZAR, TRY, THB, SAR, BTC) by default, or specify targets:

{ "base": "BTC", "targets": ["USD", "EUR", "INR", "GBP"] }

Output:

{
  "base": "BTC",
  "rates": {
    "USD": 51234.56,
    "EUR": 47345.12,
    "INR": 4258567.12,
    "GBP": 40567.89
  },
  "timestamp": "2026-02-14T12:00:00.000Z",
  "source": "coinbase",
  "cached": false
}

Single date:

  "base": "USD",
  "target": "INR",
