Introducing the Ocelloids Assets Price API

Tech Talk
1

We’re launching a new addition to the Ocelloids API suite: the Assets Price API.

Overview

This API aggregates token prices from multiple sources, currently Binance and CoinGecko.

Core Operations

  • prices: Get prices for all supported assets
  • prices.by_ticker: Query prices for specific tickers (e.g., DOT, GLMR, HDX)
  • prices.by_asset: Fetch prices using asset identifiers
  • tickers.list: List all supported tokens
  • sources.list: View available data sources

Example

curl \
  'https://dev-api.ocelloids.net/query/ticker' \
  -H "Authorization: Bearer eyJhbGciOiJFZERTQSIsImtpZCI6IklSU1FYWXNUc0pQTm9kTTJsNURrbkJsWkJNTms2SUNvc0xBRi16dlVYX289In0.ewogICJpc3MiOiAiZGV2LWFwaS5vY2VsbG9pZHMubmV0IiwKICAianRpIjogIjAxMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwIiwKICAic3ViIjogInB1YmxpY0BvY2VsbG9pZHMiCn0K.bjjQYsdIN9Fx34S9Of5QSKxb8_aOtwURInOGSSc_DxrdZcnYWi-5nnZsh1v5rYWuRWNzLstX0h1ICSH_oAugAQ" \
  -H 'accept: application/json' \
  -H 'content-type: application/json' \
  -d '{
    "args": {
      "op": "prices.by_ticker",
      "criteria": [
        { "ticker": "DOT", "sources": ["binance"] },
        { "ticker": "GLMR" },
        { "ticker": "HDX" }
      ]
    }
  }'

Output:

         ]
      },
      {

            },
            {
               "name":"coingecko",
               "sourcePrice":0.078199
            }
         ]
      },
      {
         "ticker":"HDX",
         "asset":[
            {
               "chainId":"urn:ocn:polkadot:2034",
               "assetId":"native"
            },
            {
               "chainId":"urn:ocn:polkadot:2034",
               "assetId":0
            }
         ],
         "aggregatedPrice":0.01220897,
         "updated":1748621101318,
         "sources":[
            {
               "name":"coingecko",
               "sourcePrice":0.01220897
            }
         ]
      }
   ]
}
