Change Feeds
All high-frequency datasets support ?since=ISO8601 change feed queries, returning only records updated after the given timestamp. Your agent can poll efficiently without re-fetching unchanged data.
Payment
Verilex uses the x402 protocol for pay-per-query access with USDC on Base chain. Free endpoints (stats, samples) work without payment. Paid endpoints return HTTP 402 with payment requirements.
Data Freshness
Every paid response includes headers:
X-Data-Stale: true|falseX-Data-Last-Updated: ISO 8601 timestampX-Data-Age-Seconds: number

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
