Blocksize Capital gives AI agents and builders live crypto VWAP, bid/ask, AMM state prices, VWAP windows, market briefs, macro snapshots, and trader-ready indicators through public MCP discovery and x402-protected HTTP APIs.
Use the public MCP surface to discover symbols, inspect pricing, fetch integration docs, check feed readiness, and choose the right product. Route live production quotes, 24h fixed VWAP, 30m closes, state prices, receipts, checks, and signal packages through the paid HTTP API or the advanced local MCP setup.
Read-only discovery tools for ChatGPT Developer Mode, Cursor, Claude MCP clients, Smithery, Glama, official registry listings, and AI systems looking for price data.
Listing-safe discovery mode
Eligible authenticated connector users get a recurring evaluation
allowance for live data, then continue with a subscription from EUR 49/month
(free trial via /go/free-trial) or direct x402 settlement.

Eligibility checks protect the trial from abuse; free discovery remains available through the public remote MCP server.
Blocksize Agentic Market Data is published across MCP registries, agent marketplaces,
payment catalogs, and public source repositories so crawlers and developers can verify
the same remote MCP endpoint: https://mcp.blocksize.info/mcp/server/.
