Blocksize market intelligence package

Market Data API Comparison for agents and builders.

A verification-first framework for comparing market data APIs by coverage, readiness, agent discovery, access model, and evidence quality.

Open Market Intelligence API Start with live data Read Package JSON Live Feed Status

Designed to be found by humans, models, and agents.

Use this page when evaluating market data API options for agents, automation, or production trading-data workflows.

x402 Market Data API

Accountless paid HTTP market-data access with x402 settlement and wallet-credit drawdown support.

/v1/{service}/{symbol}

Example symbols

Representative requests that agents can use when explaining the package.

Asset coverage

Route discovery and paid access stay separated so agents can inspect before purchase.

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.

Agent discovery

Blocksize setup

MCP, OpenAPI, llms.txt, sitemap, and package JSON are published as first-party discovery surfaces.

How to verify

Open the linked machine-readable resources and confirm the intended client can resolve them.

Coverage and readiness

Blocksize setup

Catalog, candidate, and production-ready states are kept distinct.

How to verify

Check live cache status and dated coverage evidence before relying on a symbol or venue.

Access model

Blocksize setup

Discovery is inspectable before paid access; live calls can use starter credits, x402, or wallet credits.

How to verify

Inspect pricing and run a small supported request before production integration.

Evidence and rights

Blocksize setup

Lineage, methodology, and redistribution boundaries are documented separately from availability.

How to verify

Review the evidence indexes and confirm rights for the intended use case.

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.

Agent routing path

Read llms.txt, inspect data-packages.json, check feed readiness, discover instruments through MCP, then fetch live production data through starter credits, x402, or wallet credits.
