Strengths

Solana on-chain agent trust scoring via MCP; 4 free tools to score, resolve and verify AI agent wallets.

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.

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