whaletape-mcp-server

Tools

  • whaletape_consult(intent) — free, never bills. Returns which route to call and its price.

  • whaletape_catalog() — free. All routes, prices, networks.

  • whaletape_free(path) — free routes: /preview/whales, /preview/signals, /preview/squeeze (real samples of paid data), /markets/preview, /public/stats, /track-record, /metrics, /health.

  • whaletape_fetch(path, method?, body?) — paid. Pays the 402 quote automatically and returns data + on-chain receipt. A 4xx/5xx answer is never billed.

Without MCP

Any x402 client works — the routes speak plain HTTP 402. Two pages are generated from the live catalog, so their prices are always the ones the 402 charges:

  • https://whaletape.xyz/skill.md — for agents with a shell or MCP

  • https://whaletape.xyz/skill-automaton.md — for autonomous agents that pay on Base

Machine-readable catalog: https://whaletape.xyz/.well-known/x402

Free routes, no wallet needed

/preview/whales, /preview/signals, /preview/squeeze are real samples of the paid data. /track-record publishes the measured hit rate of our own squeeze radar, bands and sample sizes included — read it before trusting a score.
