Overview

Welcome to the Covalent API!

The Covalent Unified API can be used to pull token balances, positions and historical granular transaction data from dozens of blockchain networks. This data enables hundreds of end-user use-cases like wallets, investor dashboards, taxation tools and as-of-yet unknown use-cases.

Switching from one blockchain network to another is simply changing the chain_name path parameter. It's really that simple.

One Unified API. One Billion Possibilities.

The Covalent API is RESTful. The API is designed around the main resources that's available through the web interface. Sample API calls are provided next to each method using cURL.

Broadly speaking, there are three classes of APIs:

  • Class A - APIs that return enriched blockchain data applicable to all blockchain networks, eg: token balances, transactions, log events, etc.

  • Class B - APIs maintained by Covalent for a specific protocol on a specific blockchain, eg: Constant Product AMMs (XY=K) on various blockchains.

  • Class C - APIs created and maintained by the community.

URL Patterns

The API Host for all requests is https://api.covalenthq.com/v1/. Some additional points to keep in mind:

  • The current version of the API is v1.

  • All requests are done over HTTPS (calls over plain HTTP will fail.)

  • The default return format for all endpoints is JSON, unless the query parameter format=csv is specified.

  • All requests require authentication.

Authentication

To access the Covalent API, you will need an API key. You can find your API key in the web interface. Various authentication mechanisms are available:

Authentication via Query parameter

curl -X GET https://api.covalenthq.com/v1/ENDPOINT/?key=API_KEY

Simply append key=API_KEY as a query parameter to all requests. The main advantage of this method is to embed the API endpoints within applications that do not support more sophisticated auth mechanisms, like Google Sheets or as IFrames.

Authentication via Basic Auth

curl -X GET https://api.covalenthq.com/v1/ENDPOINT/ \
     -u API_KEY:
     -H 'Content-Type: application/json'
     # The colon prevents curl from asking for a password.

Provide your API key as the basic auth username. You can find your API key in the web interface. You do not need to provide a password.

Use of $CQT (Covalent Query Token)

The Covalent API does not require the CQT token in order to use it. CQT is a staking and governance token and for every API call, CQT is market bought and distributed to the service providers who are fulfilling the API requests. This "fee switch" mechanism is yet to launch.

Response format

❴ 
    "data": ...,
    "error": false,
    "error_message": null,
    "error_code": null
❵

By default, the Covalent API returns JSON responses with the same shape for all endpoints. The main keys are data, error, error_message and error_code.

You can ask for a CSV format by sending the format=csv query parameter.

Supported Networks

Covalent supports over 100+ different blockchains all with the same unified API. For a full list see here.

Rate limiting & Premium Tier

We have a limit of 5 requests per second per API key for free users. Furthermore, free users are also limited to 100,000 credits per month, reset on the first of each month.

If you upgrade to a Premium Tier, you get access to higher rate limits and the ability to unlock flex credits.

Refresh rate

We classify the APIs as:

  • real time

  • batched

Real-time endpoints have a delay of 2 blocks – for example, on blockchains like Ethereum with block times of 15 seconds, the delay will be 30 seconds which on blockchains like Polygon with blocktimes of 3 seocnds, the delay will be 6 seconds.

Batched endpoints have a delay of 30 minutes.

Pagination

Certain endpoints take two parameters: page-size and page-number implementing offset-limit pagination.

Error codes

Covalent uses standard HTTP response codes to indicate the success or failure of an API request. In general: codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, etc.). Codes in the 5xx range indicate an error with Covalent's servers (these are rare).

CodeDescription
200 - OKEverything worked as expected.
400 - Bad RequestThe request could not be accepted, usually due to a missing required parameter.
401 - UnauthorizedNo valid API key was provided.
404 - Not FoundThe request path does not exist.
429 - Too Many RequestsYou are being rate-limited. Please see the rate limiting section for more information.
500, 502, 503 - Server ErrorsSomething went wrong on Covalent's servers. These are rare.
