Safecast Recently Reporting Devices (Radiation and Air Quality)

safecasttt/recent-devices

Returns a summary of the Safecast citizen science network of fixed radiation and air quality devices: the total number of devices, a count per country, and the 50 most recently reporting devices with location, place name, temperature, humidity, pressure, battery, radiation counts and PM1.0, PM2.5 and PM10 particulate values where the device measures them. Each Notecard-based device carries a device_id for the device-readings tool. Takes no input. Safecast data as served by Eden Engine, not an official Safecast product.

Price

$0.0026 per call

You pay the price shown. If a call turns out to cost more than its quote, you pay the actual price, capped at twice the quote. No monthly minimum. Top-ups start at $0.50.

Data source

Safecast

Radiation and air quality readings from Safecast (safecast.org), a citizen science project whose data is released to the public domain. No attribution is required; we credit Safecast as a courtesy. Served by Eden Engine; not an official Safecast product.

Use it

Five steps: search, inspect, learn, run, settle. No per-tool setup; your agent reaches this tool through the meta-tools it already has.

Connect once and your AI can find and run this tool, and any other it needs.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "safecasttt/recent-devices" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "safecasttt/recent-devices" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "safecasttt/recent-devices", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "safecasttt/recent-devices", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
