Data your software can buy itself. No signup. No API key. No account.
Every endpoint answers with HTTP 402 and a machine-readable price. Your agent pays in stablecoin and retries — one round trip, no human in the loop. Settlement is verified on-chain before a single byte is returned.

payload.transaction and a facilitator settles itEvery live-data endpoint and the guide catalog are also exposed as tools over Streamable HTTP MCP at https://saylorinnovations.com/mcp — add it as a tool server to Claude or any MCP-compatible agent and it can list, sample and buy directly, no custom integration code.
https://saylorinnovations.com/mcp — connect as an MCP tool serversaylorinnovations.com. Use the URLs exactly as published in the manifest — that is the authoritative source.x402 is an open protocol that reuses the HTTP 402 Payment Required status code as a real, machine-readable price quote. A server responds 402 with exact payment terms, the client pays on-chain, and retries the same request with proof of payment attached. No accounts, no API keys, no subscriptions — pay per call.
An agent reads the 402 response, builds a small on-chain payment in USDC, USDT or SOL (or USDC on Base), and retries with an PAYMENT-SIGNATURE header. Settlement takes a few seconds to confirm, so a client should retry 3-4 times over 10-20 seconds rather than treating an initial "not found yet" as failure.
Yes. /mcp is a Streamable HTTP MCP server. Connect it as a tool server to Claude or any MCP-compatible client and it exposes every live-data endpoint plus the guide catalog as callable tools, each with a free sample and its price.
Yes. Every paid endpoint has a matching /api/sample/{kind} route that returns a real response for a fixed subject, free, so an agent can confirm the exact shape and data quality before spending anything.
Same underlying intelligence, two audiences. The scanner at crypto.saylorinnovations.com/scanner/ is the free browser tool for humans — paste an address, get a score. This API sells that same intelligence per request to software: agents, bots, and anything querying many tokens programmatically.
