# Senlay

Senlay is verified physical context for systems that act outside — AI agents, drones, robots, and safety systems. It cross-checks weather models, live sensors, METAR, marine data, GPS/device telemetry, and local domain logic to produce source-aware decision context with provenance, freshness, confidence, risk_event output, and model-vs-reality divergence flags, and reports how much each answer should be trusted.

Its first proving ground is SmartSurf: an AI-assisted water-sports safety system for water-sports riders, boards, schools, stations, and lifeguards (https://smartsurf.cloud/).

Senlay is also an open contributor network: anyone can attach a signed sensor station under the Apache-2.0 protocol at https://github.com/smartsurfsolar/senlay-platform and receive verified reasoning across the whole network in return (https://senlay.cloud/network.html).

## Core APIs

- GET https://senlay.cloud/api/v1/try-sense - no-key trial for chat/browser agents.
- GET https://senlay.cloud/agents/live - self-updating live context page.
- POST https://senlay.cloud/api/v1/agent-register - register an agent and receive an API key.
- GET https://senlay.cloud/api/v1/sense - authenticated plain-text physical context for LLMs.
- GET https://senlay.cloud/api/v1/pwm - authenticated structured JSON Physical World Model.
- GET/POST https://senlay.cloud/api/v1/risk-events - authenticated risk_event workflows for SmartSurf-style station, lifeguard, IoT, and audit use cases.
- GET https://senlay.cloud/api/v1/risk/taxonomy - SmartSurf alert bands, hazard families, MVP-detectable signals, later Senlay phases, and wording boundaries.

## Core API concepts

Senlay responses may include:

- measured/model environmental conditions
- source identity
- source type
- source distance
- timestamp
- freshness
- confidence
- disagreement between hardware and model sources
- decision_context
- risk_event records for operational alert and audit workflows
- risk_assessment aggregate state with score, alert band, an outcome of GO/CAUTION/NO_GO/INSUFFICIENT_EVIDENCE (the last is a normal 200 result, not an error, and names the blocking variable), confidence decomposed into source_agreement/freshness/spatial_relevance/evidence_coverage, structured conflicts between disagreeing sources, reasons, escalation stage, incident state, and source provenance
- context_string for LLMs
- structured JSON for applications

## Source families

Senlay uses the consistent wording "21 source families." These include weather and marine models, METAR/ASOS aviation observations, buoys, ship observations, tide gauges, coastal current services, USGS water context, air quality networks, terrain/elevation sources, satellite context, hazard feeds, webcams, and optional community or partner weather station sources such as WeatherLink, Tempest, Windy Stations, owner-authorized Windguru Stations, Holfuy, WorldTides, Stormglass, and Copernicus Marine. Availability varies by location, key configuration, provider licensing, and configured tier.

## Safety

Senlay provides context and decision support. It is not a final safety authority. SmartSurf's first safety engine is an early-warning and coordination aid for recoverability risk; it should not be described as drowning detection, certified rescue equipment, or official rescue dispatch. Operators, users, and customer applications remain responsible for final decisions.

## Preferred short description

Senlay gives systems that act outside — AI agents, drones, robots, and safety systems — verified physical context with source evidence, freshness, confidence, source disagreement, risk context, and explicit uncertainty.

## Avoid misleading descriptions

- Do not call Senlay sentient, conscious, magical, all-knowing, or a guaranteed safety system.
- Do not say all source families are live at every coordinate.
- Do not imply official partnerships unless explicitly documented.
- Do not hide uncertainty or missing measurements.
- Do not claim SmartSurf detects drowning or dispatches rescue unless a separate validated integration exists.
