- Include the header
X-CMC_PRO_API_KEY: your-api-key in all requests
curl -X GET "https://pro-api.coinmarketcap.com/v1/exchange/map" \
-H "X-CMC_PRO_API_KEY: your-api-key"
Base URL

Common Use Cases
See use-cases.md for goal-based guidance on which endpoint to use:
- Get exchange information by name
- Find an exchange's CMC ID
- Get top exchanges by volume
- Get only spot exchanges (or only derivatives)
- Get current volume for a specific exchange
- Compare volume across multiple exchanges
- Get historical volume for an exchange
- Get all trading pairs on an exchange
- Find BTC pairs on an exchange
- Get perpetual/futures pairs on an exchange
- Check exchange reserves (proof-of-reserves)
- Find exchanges that list a specific coin
API Overview
Common Workflows
Get Exchange Information
Why: Most endpoints require CMC exchange IDs, not names. The map endpoint translates human-readable slugs to IDs.
- Call
/v1/exchange/map with slug=binance to get the exchange ID
- Call
/v1/exchange/info with the ID to get full metadata
Compare Exchange Volumes
Why: Volume indicates liquidity and trustworthiness. Higher volume means better price execution and lower slippage.
- Call
/v1/exchange/listings/latest to get all exchanges ranked by volume
- Use
sort=volume_24h and sort_dir=desc for descending order
Analyze Trading Pairs
Why: Understanding available pairs helps users find where to trade specific assets and compare liquidity across venues.
- Get the exchange ID from
/v1/exchange/map
- Call
/v1/exchange/market-pairs/latest with that ID
- Filter by
category=spot or category=derivatives as needed
Track Volume History
Why: Historical volume reveals trends. Declining volume may signal user exodus. Spikes may indicate wash trading or news events.
- Get the exchange ID from
/v1/exchange/map
- Call
/v1/exchange/quotes/historical with date range parameters
Query Parameters
Most endpoints accept these common parameters:
| Parameter | Type | Description |
|---|
| id | string | CMC exchange ID (comma-separated for multiple) |
| slug | string | Exchange slug (e.g., "binance") |
| convert | string | Currency for price conversion (default: USD) |
| aux | string | Additional fields to include in response |
Error Handling
All responses include a status object:

"error_code": 0,
"error_message": null,
"credit_count": 1

}
Common Error Codes
| Code | Meaning |

| 401 | Unauthorized (invalid API key) |
| 403 | Forbidden (plan limit exceeded) |
| 429 | Rate limit exceeded |

Rate Limits
Rate limits depend on your subscription plan. Check the credit_count in responses to track API credit usage. The X-CMC_PRO_API_KEY header must be present on every request.
Response Format
All responses return JSON with this structure:
{
"status": { },
"data": { }
}
The data field contains either an object (single item) or array (multiple items) depending on the endpoint.
