METIS

Research your software can consume

Humans and machines read the same research object. Public endpoints serve published summaries and full objects for free. Premium access, priced per request over the x402 protocol, adds the enriched evidence graph, per-asset signal feeds, and webhooks.

How x402 access works

Request

Call a premium endpoint. Without an entitlement, the API answers HTTP 402 with machine-readable payment requirements: price, currency, network, and expiry.

Pay

Your client settles the request using a supported x402 flow. No account creation, no API key onboarding, no subscription.

Receive

Settlement is verified and a short-lived entitlement fulfills the request. Retries are replay-safe and never double-charge.

The premium gateway ships in a later phase. Everything labeled public above is live today; responses carry stable error codes, ETags, and cache headers. Agent-friendly discovery lives at /llms.txt.
