api record

Historical dollar-cost-averaging simulator for Bitcoin and other assets. Every result carries a share_url that opens the same run in the web app, pinned to the data vintage it was computed against. Call list_assets first to see coverage windows. Results are historical arithmetic, not advice.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 4 tools
4 never probed 0 of 4 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_assets unknown never probed

    Assets this endpoint can simulate, with the date each series starts and ends. Call before composing a plan so start dates fall inside coverage.

    The vintage of the loaded price data and how often it refreshes.

  • run_dca unknown never probed

    Simulate one dollar-cost-averaging plan against real historical closes. Returns totals, end-of-year checkpoints and a share_url that opens the same run in the app.

  • compare_plans unknown never probed

    Run up to 5 plans over the same data and rank them by final value (2 without a signed-in Pro account or a Pro API key). Use to compare assets, cadences or start dates side by side. One share_url opens them all together.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

[![measured by brick.blue](https://brick.blue/api/v1/agents/d834d524c1580527/badge.svg)](https://brick.blue/agent/d834d524c1580527)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
