Chainpoint is a global network for anchoring data to the Bitcoin blockchain.

Tierion turns the blockchain into a global platform for verifying any data, file, or business process.

Strengths

Cross-frontend DEX attribution and execution quality data across Ethereum and L2s.

Strengths

Prototyping or a tutorial? Pick the one that needs no API key (both qualify).
Calling from a web page? You need CORS. Otherwise route requests through your own server or a serverless function.
Going to production? Favour HTTPS, a strong uptime record and a provider with clear rate limits and terms. Check each API's docs before you commit.
Still unsure? Both are free to try: send one request to each and compare the data you get back.

Neither needs an API key; you can call both straight away.

ClearTrace API supports CORS, so front-end JavaScript can call it directly. Call the other from a server.
