  - after: Live full pulse ($0.02 USDC on Solana via x402 after free quota). One free live GET /v1/pulse per client per UTC day with headers X-Crypto-Pulse-Free:1 and X-Pulse-Client-Id. Bare GET still returns HTTP 402 for x402 discovery. This MCP tool returns payment requirements + HTTP URL. Free stale preview: get_market_sample.
