Seiche — world-markets evidence terminal

SEICHE

Release scope: 28 October 2026

Eight public research tools are available: source_rights_status, money_market_context, market_workbench, world_markets_context, gift_city_context, gold_inventory_carry, research_network, data_health. Start with source_rights_status. Retired forecasts, backtests, editorial, composite and derived legacy tools are unavailable for every caller while their source reuse rights and replacements remain unqualified. A bearer token or payment does not unlock them. Do not reconstruct withheld observations from metadata, cached history or prior responses. Direct publisher observations keep their own dates; restricted inputs remain explicitly metadata-only. Authenticated callers can additionally discover five private, non-executable Agent Room tools. Earlier feature descriptions below are historical context where they conflict with this release scope; they do not advertise availability.

For a connected review, ask for institution evidence → funding context → BTC exit estimates, with each source date, coverage gap and limitation kept separate. Client/model costs and fair-use limits may apply. Research calls do not execute trades.

Choose the tool by the answer you need

Start with source_rights_status for feature availability and data_health for source clocks and faults. The broader tools have different jobs:

Start with the row matching the task. The tool selection guide includes all public tools, example questions and a repeatable funding-review workflow.

Public US dollar funding research from source-dated Fed and Treasury observations. Live board: seiche.info.

Dated answers to common research questions explain the numbers, source dates and limits.

LiquiLens, Seiche and Undertow are connected research products from LIQUILENS PRIVATE LIMITED, a registered company in India. Built for international review workflows: institution evidence → funding conditions → market liquidity. Market coverage, source clocks and authority remain specific to each product.

A seiche is a standing wave in an enclosed body of water — invisible from the

shore, until it sloshes over the edge. Funding stress behaves the same way.

Seiche is a free, open source (AGPL-3.0-or-later) money-, foreign-exchange and capital-market evidence terminal organized around the dollar funding system — US money markets, 22 public H.10 currency reference series, the Treasury capital-market complex, the global basins connected through swap lines, and the offshore-dollar crypto basin moored to the T-bill market through stablecoins. The core US board and USD desk use free official/public APIs (FRED, NY Fed Markets, OFR STFM, Treasury FiscalData, CFTC, ECB Data Portal, DeFiLlama, Coinbase Exchange). The global market-pack catalog can also declare licensed or tenant sources, but public outputs obey each source's redistribution policy and never expose restricted raw values.

Seiche publishes a construction-PIT historical diagnostic—with misses and eligibility limits kept visible—and is now accruing a separate as-published forward record that can be verified instead of reconstructed. Licensed terminals provide much broader real-time data and execution workflows, while OFR and NY Fed dashboards provide authoritative source views. Seiche is a narrower, opinionated research layer: forward-looking, alerting-ready, and provenance-honest. It is not a Bloomberg/Reuters replacement, a real-time quote service, or an execution venue.

The lab

Seiche is one of three altitudes in a single liquidity lab that fills that gap: Seiche reads the plumbing, [LiquiLens](https://liquilens.in) organizes institution evidence for review, and Undertow measures market liquidity itself (who provides depth in each segment, what an exit at position size costs today). The wiring between the three is real, not a brochure: the desk assistant pulls the LiquiLens failure board over MCP, the MARKET tab renders Undertow's published pack live, and the Windfetch engine reads the FETCH pack built in the Undertow repo back into this board. On names: the internal composite engine called "undertow" (critical slowing down, engines/undertow.py) is unrelated to the Undertow sister product.

For a first connected review, start with funding context in the browser. The shared portfolio plan prioritizes a recurring reviewer task while keeping each product's evidence and authority separate.

For a recurring agent workflow, the free starter kit combines Seiche funding context with LiquiLens bank evidence and Undertow exit estimates. Use the Hermes or OpenClaw setup guide. The selected public tools need no API key; fair-use limits and separate model-provider costs apply.

Use Seiche everywhere

Seiche is distributed as software, an MCP service, a research dataset, and machine-readable catalog metadata. Status is receipt-based: listed means a durable public record and receipt exist, prepared means an owner-controlled submission or publication remains, and blocked means a named prerequisite must clear first. “Usable in repo” describes local artifact readiness, not a ledger status. The auditable source of truth is distribution/submissions.csv.

Version 0.16.3 estuary checks the four monthly OFR money-market-fund series and six quarterly BIS series daily while preserving their observation dates and native release cadence. Signed deployment and publication acceptance are required before this source change is live.

Version 0.16.2 estuary prepares the reviewed Google-Extended policy, three dated dollar-funding answers and Riptide's public paper allocation beside the Market desk. The policy permits grounding/training only on three reviewed original explanations; source data, archives and other pages remain excluded. New signed application and publication receipts are required before these changes are live. The inherited 0.16.1 release connects the UAE DONIA reference to GIFT City's AED card and retains country funding and sovereign references for China, Japan, South Korea, Taiwan, Australia, the United Kingdom, all 21 euro-area countries and seven other European countries. Official observations retain their source dates, native frequency and gaps. The eight public MCP tools expose the country catalog through money_market_context(section="countries"); add country="JP" for a country desk or use section="india" for the India desk. New official SOFR, EFFR, IORB, overnight reverse-repo and New York Fed funding observations can reach the daily review without waiting through the previous four-to-twelve-hour cache windows. Failed refreshes retain the original source dates and stale warnings. Deployment and immutable package publication remain subject to signed release gates.
