Physical-world context infrastructure

The multi-field sensory layer for AI agents.

AI agents can reason, write, and plan — but they cannot sense what is happening outside. Senlay connects them to live sensors, environmental models, terrain, oceans, hazards, and device telemetry, then returns evidence-backed context they can use before acting.

Why Senlay exists

Agents should not guess when the world can be measured.

Training data can describe a place. A generic API can return a number. Senlay adds the missing trust layer: what was observed, where it came from, when it was measured, whether sources agree, and how much the result should influence a real-world decision.

Sense

Bring fragmented signals together.

Hardware sensors, public networks, forecast providers, satellite events, terrain, marine feeds, GPS tracks, and customer IoT devices enter through one integration layer.

Verify

Attach evidence to every answer.

Observations and predictions stay distinct. Freshness, proximity, confidence, source health, and model-versus-reality disagreement remain visible instead of being hidden.

Interpret

Return context an agent can act on.

Field-specific rules turn raw readings into structured context, risk events, and plain-language uncertainty without pretending the API is a final safety authority.

One core, many fields

A horizontal sensing layer with domain-aware outputs.

The evidence contract stays consistent while the sources, rules, and decision context adapt to each physical workflow.

Autonomous and drone operations

Wind, gusts, precipitation, visibility, terrain exposure, airspace weather, and go/no-go context.

Marine and water safety

Waves, tides, current, buoy observations, wind direction, coastal geometry, GPS drift, and rescue-margin context.

Agriculture and field work

Heat, humidity, evapotranspiration, frost, precipitation, soil-relevant context, and spray-window conditions.

Environmental monitoring

Air quality, fire and hazard feeds, satellite events, earthquakes, volcanoes, and source freshness.

Connected products and IoT

Private station networks, trackers, device telemetry, customer sensors, webhooks, and normalized evidence records.

AI assistants and workflows

Agent-ready context strings, versioned JSON, API-key access, model integrations, and auditable risk events.

How it works

From unreliable upstreams to explainable agent context.

Senlay is an end-to-end production system, not a static concept page. It handles provider integrations, normalization, trust logic, authentication, persistence, API delivery, and Linux deployment behind a public HTTPS service.

01 · Integrate

Source adapters

Connect weather, marine, aviation, environmental, satellite, and private-device APIs with bounded timeouts and explicit licensing controls.

02 · Normalize

Evidence contracts

Convert incompatible payloads into versioned observations, predictions, static context, provenance, and source-health records.

03 · Reason

Context and risk

Fuse local evidence, terrain modifiers, fallback policy, domain rules, and disagreement into machine- and human-readable outputs.

04 · Operate

Production delivery

Serve through Node/Express, SQLite, Nginx, PM2 or Docker with secrets isolation, health checks, logs, backups, and deployment runbooks.

Engineering proof

Built to be diagnosed, supported, and deployed.

The project demonstrates the work between “API idea” and “reliable service”: tracing failures across integrations, validating responses, managing Linux runtime state, protecting credentials, documenting boundaries, and communicating what the system knows and does not know.

API troubleshooting

Authentication, validation, rate limits, upstream errors, normalized responses, OpenAPI contracts, and reproducible test requests.

Linux / VPS operations

Nginx reverse proxying, PM2 processes, environment configuration, filesystem permissions, runtime data, smoke checks, and recovery steps.

Integration resilience

Timeouts, caching, singleflight requests, graceful degradation, source-health tracking, and transparent fallbacks when providers fail.

Technical communication

Public docs, agent-readable manifests, deployment guides, decision boundaries, provenance, and clear explanations for developers and operators.

First real-world proof

SmartSurf is where the sensory layer meets water.

Senlay grew from a practical problem: outdoor decisions depend on local reality, while models and nearby sensors can disagree. SmartSurf applies the same evidence engine to riders, boards, schools, GPS trackers, weather, marine conditions, and water-safety workflows.

Software

Phone-first safety workflow

Sessions, GPS location, emergency contacts, local conditions, alerts, and operational history.

Hardware

Tracker and sensor integration

Waterproof GPS/SOS devices and private telemetry add live rider, board, and fleet signals to environmental context.

Deployment

From prototype to service

A working vertical that connects physical hardware, backend APIs, risk logic, dashboards, documentation, and production infrastructure.
