RECORD ARECORD B
A shared perspective
One connection can matter.
The other readings stay in view.
BUILD ON WHAT IS THERE
From a broad question
to the record underneath.
15 tools hold 81 operations over 74 documented datasets. Each result states its retained scope and dates.
Explore another perspective
Follow publication references to captured research abstracts. Explore authorship, affiliations and individual instrument matches across a retained selection of 305,563 retained research records.
Keep the evidence close
Open Treasury, Federal Reserve, BLS, BEA and CFTC observations and retained revisions. Compare changes in money, prices and equity accounts across time. Compare Prime fund managers, changes and concentrations, then reopen their original holdings. Follow fund reports through accounting comparisons, amendments and original SEC holdings. Inspect separate instrument outputs and child measurements. Publication dates and capture times remain distinct.
Each tool covers one area: markets, SEC filings, funds, rates and Treasury, liquidity, government and companies, world events, research literature and more. Your agent names a tool and sets op to one of its operations. Over MCP, agents see only the tools their key can use plus four free helpers. See every tool and operation →
Association results are research observations. They do not establish causality, calibrated relevance or an admitted full meaning panel. Financial, publication-reference and research coverage is qualified per capability. Publisher article text and additional readers are being qualified separately.
PAY FOR THE READ
A price before every operation.
Prepay $20–$500. No automatic recharge. Your own model handles the conversation; CalyxCash provides the data and processing.
METADATA
$0.002/ readSource coverage, captures, retained revisions, series and fund catalogues, and association overviews.
SEARCH & EVIDENCE
$0.008/ readCatalogue search, retained financial observations, fund holdings and dynamics, scholarly works, publication-reference members, research abstracts and association record, parts or evidence views.
ASSOCIATIONS
$0.02/ readInstrument neighbors, authorship, topics, affiliations, fund-report and time-series comparisons, valuation and context diagnostics.
Capability discovery, quotes and receipt replays are free. Successful reads consume credit, including an empty result. Failed operations are uncharged. A few views are priced between these tiers; every operation’s exact price is in the docs. Each page is a read. One account balance pays for API reads and website research questions; the tools pass is separate.
