How to evaluate this category.

Compare verifiable product boundaries and run the same acceptance tests against every option. No competitor capability is asserted on this page.

Data product

Blocksize setup

VWAP, bid/ask, fixed-window VWAP, state price, and derived briefs are separate packages.

How to verify

Match the decision to the exact route and avoid substituting a spot quote for a calculated VWAP.

Freshness

Blocksize setup

Readiness and cache status are exposed independently from catalog availability.

How to verify

Set a freshness threshold and test behavior when a source is stale or unavailable.

Automation fit

Blocksize setup

Agents can discover routes over MCP and call paid HTTP endpoints without an account-first workflow.

How to verify

Test discovery, payment challenge handling, delivery, and failure recovery end to end.

Verify the claim before production use.

Live status, dated coverage, lineage, and licensing evidence are published separately so catalog visibility is never presented as production readiness.
