Authentication

The Transpose Verified Endpoints suite can be accessed with any valid Transpose API key. To authenticate, simply include the case-insensitive X-API-KEY request header with your API key as the value. It's that easy!

API Key

Before proceeding, we need to authenticate ourselves with Transpose. To access any Transpose API, you'll need an API key. All API requests should include your API key in an X-API-KEY header. If you haven't already, you'll need to sign up and create a team (for free!). Once you have a team, you can find a list of your API keys in your team dashboard. When you have your API key, replace <YOUR-API-KEY> in the interactive examples below with your key.

Remember not to share your API key! Your API key is a secret, and should not be stored or exposed in a public manner.

Basic Example

PythonNodecURL

import requests url = "https://api.transpose.io/block/blocks-by-number" headers = { 'Content-Type': 'application/json', 'X-API-KEY': 'BtRVYj7dgnYUcr1gSSfWhmrTShIb8RBG', } params = { "chain_id": "ethereum", "order": "desc", "limit": "1", } response = requests.get(url, headers=headers, params=params) print(response.text) print('Credits charged:', response.headers.get('X-Credits-Charged', None))

const https = require('https'); const querystring = require('querystring'); const params = { chain_id: "ethereum", order: "desc", limit: "1", } var options = { hostname: 'api.transpose.io', path: '/block/blocks-by-number?' + querystring.stringify(params), method: 'GET', headers: { 'X-API-KEY': 'BtRVYj7dgnYUcr1gSSfWhmrTShIb8RBG' } }; var req = https.request(options, (res) => { console.log('Credits charged:', res.headers['x-credits-charged']); res.on('data', (d) => { process.stdout.write(d); }); }); req.on('error', (e) => { console.error(e); }); req.end();

curl -X GET \
    'https://api.transpose.io/block/blocks-by-number?chain_id=ethereum&order=desc&limit=1' \
    -H 'X-API-KEY: BtRVYj7dgnYUcr1gSSfWhmrTShIb8RBG' \
