Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| GAUGE_BASE_URL | No | Base URL of the GAUGE service. Default: https://aeml-x402.zeabur.app | https://aeml-x402.zeabur.app |
| GAUGE_MAX_USDC | No | Atomic per-call cap in USDC (smallest unit). Default: 120000 ($0.12). | 120000 |
| EVM_PRIVATE_KEY | No | 0x Base-mainnet wallet key; needs a little USDC (EIP-3009 gasless, no ETH). Required for paid tools; omit for free tools only. |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| gauge_catalogA | List all GAUGE signals — hydrology (river level/streamflow), air quality (AQI/PM2.5), precipitation/drought, agriculture (drought/heat/crop VHI), power grid (demand/renewables/energy inflation), shipping (route disruption/sea state/AIS throughput), regulatory filing (8-K/late filing/insider) — with the entities you can query. Free, no payment. |
| gauge_previewA | GAUGE coverage counts, à-la-carte pricing menu, and the lists of region/company bundles (regions, agri_regions, grid_regions, shipping_regions, filing_watchlist). Use this to discover what to buy. Free. |
| gauge_sampleA | A free full sample GAUGE record — shows exactly what a paid response contains: current reading vs official thresholds (band, distance-to-action), seasonal statistical anomaly (percentile/strata), sources + record_hash provenance. Try before you buy. |
| gauge_river_freeA | Free raw US river reading (gage height / streamflow) for a USGS site id — current/previous/change/trend/sources/record_hash. No payment. Example site 07010000 = Mississippi at St. Louis. |
| gauge_flood_riskB | Verifiable flood-risk / anomaly record for one signal+entity: current vs official USGS/NOAA/EPA/CAMS thresholds (band, distance-to-action) + 5yr seasonal anomaly (percentile/strata) + record_hash. Costs $0.05 USDC on Base via x402. Works for hydrology/air/precip signals. |
| gauge_regionA | Three-leg region bundle for a US city: air quality + precipitation + nearby river, with cross-line corroboration narrative. Costs $0.10 USDC on Base. loc e.g. us-stlouis, us-chicago (see gauge_preview regions). |
| gauge_crop_droughtA | Agriculture triangle for a grain region: agricultural drought (soil moisture vs official USDM D0–D4) + heat/GDD + crop vegetation health (NOAA satellite VHI) + cross-validation (has drought hit the crop canopy). For ag traders & crop insurers. Costs $0.10 USDC on Base. loc e.g. us-iowa, ar-pampas, ua-ukraine. |
| gauge_grid_stressA | Power grid triangle for a grid region: electricity demand pressure (temperature HDD/CDD load proxy) + renewable resource (solar/wind) + energy inflation (US CPI Energy YoY) / natural gas price + cross-validation (high demand × low renewables = grid squeeze → energy inflation). For power/energy & macro/inflation traders, utilities. Costs $0.10 USDC on Base. loc e.g. us-ercot, us-caiso, eu-germany. |
| gauge_route_disruptionA | Shipping/port triangle for a chokepoint: logistics-flow disruption (WMO sea state + wind vs operational thresholds) + sea-state cause (wave decomposition: local-storm vs distant-swell) + live AIS vessel throughput (waiting vs transiting + congestion) + cross-validation. For shipping lines, commodity/freight traders, ports, marine insurers. Costs $0.10 USDC on Base. loc e.g. malacca, suez-redsea, hormuz, channel. |
| gauge_filing_checkA | Regulatory-filing triangle for a company: 8-K material events (item severity — bankruptcy/default/restatement/delisting = critical) + NT late-filing delinquency (distress leading indicator) + Form 4 insider net open-market buy/sell + cross-validation (do insiders confirm the distress by selling or contradict it by buying). All official SEC EDGAR. For event-driven/activist/short funds, quant funds, credit & distressed analysts. Costs $0.10 USDC on Base. entity = ticker e.g. AMC, CVNA, GME. |

TDQS
Scored across 10 tools
Each tool has a clearly distinct purpose: catalog vs preview, free raw data vs specialized triangles for different domains (crop, filing, grid, route), region bundle, and sample. No two tools seem to overlap.
Tool names follow a consistent 'gauge_<domain>' pattern with snake_case. Minor inconsistency: 'gauge_catalog' and 'gauge_preview' both are listing tools, but the naming is mostly predictable.
Ten tools is well-scoped for a specialized data server covering multiple domains (hydrology, air quality, agriculture, grid, shipping, regulatory). Each tool earns its place.
The tool surface covers major signals from the catalog, but some signals (e.g., standalone air quality) only appear in bundles, and there are no tools for updating data. Overall, it's complete for a read-only data retrieval server.
