Pinata SDK - Pinata Docs

Overview

The Pinata NodeJS SDK provides the quickest / easiest path for interacting with the Pinata API.

Installation

npm install --save @pinata/sdk

Setup

Pinata offers developer keys for various scenarios. The most common scenario is normal IPFS actions (pinning content, unpinning, listing content, etc). These actions happen through the core Pinata API, and are documented in the Pinata API Reference.

To create an API key, visit the Keys Page and click the “New Key” button in the top right. Once you do that you can select if you want your key to be admin or if you want to scope the privileges of the keys to certain endpoints or limit the number of uses. Make those selections, then give the key a name at the bottom, and click create key.

If you are just getting started we recommend using Admin privileges, then move to scope keys as you better understand your needs

Once you have created the keys you will be shown your API Key Info. This will contain your Api Key, API Secret, and your JWT. Click “Copy All” and save them somewhere safe!

The API keys are only shown once, be sure to copy them somewhere safe!

In the example below we provided with 3 ways to call the pinata SDK.

// Use the api keys by providing the strings directly 
const pinataSDK = require('@pinata/sdk');
const pinata = new pinataSDK('yourPinataApiKey', 'yourPinataSecretApiKey');

// Use the api keys by specifying your api key and api secret
const pinataSDK = require('@pinata/sdk');
const pinata = new pinataSDK({ pinataApiKey: 'yourPinataApiKey', pinataSecretApiKey: 'yourPinataSecretApiKey' });

// Use the JWT key
const pinataSDK = require('@pinata/sdk');
const pinata = new pinataSDK({ pinataJWTKey: 'yourPinataJWTKey'});

Quickly test that you can connect to the API with the following call:

const res = await pinata.testAuthentication()
console.log(res)
// "message": "Congratulations! You are communicating with the Pinata API"!"

Usage

Once you’ve set up your instance, using the Pinata SDK is easy. Simply call your desired function and handle the results of the promise.

`hashMetadata`

Allows the user to change the name and keyvalues associated with content pinned to Pinata.
Changes made via this endpoint only affect the metadata for the hash passed in. Metadata is specific to Pinata and does not modify the actual content stored on IPFS in any way. It is simply a convenient way of keeping track of what content you have stored.

`pinata.hashMetadata(ipfsPinHash, metadata)`

Params

ipfsPinHash - A string for a valid IPFS Hash that you have pinned on Pinata.
metadata A JSON object containing the following:
- name (optional) - A new name that Pinata will associate with this particular hash.
- keyvalues (optional) - A JSON object with the updated keyvalues you want associated with the hash provided (see more below)

Adding or modifying keyvalues

To add or modify existing keyvalues, simply provide them in the following format for the keyvalues object:

keyvalues: {
    newKey: 'newValue', //this adds a keyvalue pair
    existingKey: 'newValue' //this modifies the value of an existing key if that key already exists
}

Removing keyvalues

To remove a keyvalue pair, simply provide null as the value for an existing key like so:

keyvalues: {
    existingKeyToRemove: null //this removes a keyvalue pair
}

Response

If the operation is successful, you will receive back an “OK” REST 200 status.

Example Code

const metadata = {
    name: 'new custom name',
    keyvalues: {
        newKey: 'newValue',
        existingKey: 'newValue',
        existingKeyToRemove: null
    }
};
const res = await pinata.hashMetadata('yourHashHere', metadata)
console.log(res)

`pinByHash`

Adds a hash to Pinata’s pin queue to be pinned asynchronously.

`pinata.pinByHash(hashToPin, options)`

Params

hashToPin - A string for a valid IPFS Hash (Also known as a CID)
options (optional): A JSON object that can contain following keyvalues:
- pinataMetadata (optional): A JSON object with optional metadata for the hash being pinned
- pinataOptions
  - hostNodes (optional): An array of multiaddresses for nodes that are currently hosting the content to be pinned

Response

{
    id: This is Pinata's ID for the pin job,
    ipfsHash: This is the IPFS multi-hash provided to Pinata to pin,
    status: The current status of the pin job. If the request was successful the status should be 'searching'.
    name: The name of the pin (if provided initially)
}

Example Code

const options = {
    pinataMetadata: {
        name: MyCustomName,
        keyvalues: {
            customKey: 'customValue',
            customKey2: 'customValue2'
        }
    },
    pinataOptions: {
        hostNodes: [
            '/ip4/hostNode1ExternalIP/tcp/4001/ipfs/hostNode1PeerId',
            '/ip4/hostNode2ExternalIP/tcp/4001/ipfs/hostNode2PeerId'
        ]
    }
};
const res = await pinata.pinByHash('yourHashHere', options)
console.log(res)

`pinFileToIPFS`

Send a file to Pinata for direct pinning to IPFS.

`pinata.pinFileToIPFS(readableStream, options)`

`pinata.pinList(filters)`

Params

filters (optional): An object that can consist of the following optional query parameters:
- hashContains (optional): A string of alphanumeric characters that desires hashes must contain
- pinStart (optional): The earliest date the content is allowed to have been pinned. Must be a valid ISO_8601 date.

        testKeyValue: {
            value: 'exampleFilterValue',
            op: 'exampleFilterOperation'
        },
        testKeyValue2: {
            value: 'exampleFilterValue2',
            op: 'exampleFilterOperation2'
        }
    }
}

Filter explanations:

name (optional): If provided, any records returned must have a name that contains the string provided for the ‘name’.
keyvalues (optional): Each keyvalue provided in this object have both a value and op
- value (required): This is the value which will be filtered on
- op (required): This is the filter operation that will be applied to the value that was provided. Valid op values are:
  - 'gt' (greater than the value provided)
  - 'gte' (greater than or equal to the value provided)
  - 'lt' (less than the value provided)
  - 'lte' (less than or equal to the value provided)
  - 'ne' (not equal to the value provided)
  - 'eq' (equal to the value provided)
  - 'between' (between the two values provided) - NOTE - This also requires a secondValue be provided as seen in the example below

  - 'iRegexp' (case insensitive version of regexp)

As an example, the following filter would only find records whose name contains the letters ‘invoice’, have the metadata key ‘company’ with a value of ‘exampleCompany’, and have a metadata key ‘total’ with values between 500 and 1000:

{
    name: 'invoice',
    keyvalues: {
        company: {
            value: 'exampleCompany,
            op: 'eq'
        },
        total: {
            value: 500,
            secondValue: 1000,
            op: 'between'
        }
    }
}

Our libraries support auto-pagination. This feature easily handles fetching large lists of resources without having to manually paginate results and perform subsequent requests.

To use the auto-pagination feature in Node 10+, simply iterate over a “list” call with the parameters you need in a for await loop.

`userPinnedDataTotal`

Returns the total combined size (in bytes) of all content you currently have pinned on Pinata.

`pinata.userPinnedDataTotal()`

Params

None

Response

The response for this call will the total combined size of everything you currently have pinned on pinata.
This value will be expressed in bytes

Example Code

const res = await pinata.userPinnedDataTotal()
console.log(res)

Host Node Multiaddresses

For endpoints that involve Pinata finding and pinning content that already resides on the IPFS network, you can help Pinata find your content faster by optionally providing us with the “multiaddresses” up to five host nodes that your content already resides on.

To find the multiaddresses of your nodes, simply run the following on your node’s command line:

ipfs id

In the response, you’ll want to focus on the “Addresses” array that’s returned. Here you’ll find the multiaddresses of your node. These multiaddresses are what other IPFS nodes use to connect to your node.

In the “Addresses” array, take note of the multiaddress that contains your external IP address. Not the local ipv4 “127.0.0.1” address or the local ipv6 “::1” address.

Here’s an example of what a full external ipv4 multiaddress would look like (your IP address and node ID will differ):

/ip4/123.456.78.90/tcp/4001/ipfs/QmAbCdEfGhIjKlMnOpQrStUvWxYzAbCdEfGhIjKlMnOpQr

⚠️ Please make sure every node provided is online. Pinata will attempt to connect to all nodes before pinning the content, and if any these nodes are offline, your request will eventually fail.

Pin Policies (deprecated)

A pin policy tells Pinata how many times content should be replicated, and where that content should be replicated at.

Pin policies take the following form:

Example pin policy object

{
    regions: [
        {
            id: 'FRA1',
            desiredReplicationCount: 1
        },
        {
            id: 'NYC1',
            desiredReplicationCount: 2
        }
    ]
}

The ids of currently available public regions are:

• FRA1 - Frankfurt, Germany (max 2 replications)

• NYC1 - New York City, USA (max 2 replications)
