Live Air Quality

by AgentsToolsHub in AI models & inference

x402 APIPassing, checked just now

Live air quality by city or coordinates from Open-Meteo's CAMS models: US AQI and European AQI with PM2.5, PM10, ozone, NO2, SO2 and CO concentrations. No API key, cached 30 minutes — the air-quality check agents should run instead of recalling stale numbers. Use this when an agent needs to uS + European AQI, PM2.5 and ozone by city.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.005.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://agentstoolshub.com/api/v1/live/air-quality?city=Delhi'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://agentstoolshub.com/api/v1/live/air-quality?city=Delhi' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
JavaScript: pay and call
// npm i @x402/fetch @x402/evm viem
import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

// Pays at most $0.005 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.005" });
registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? ToolVet checks it first for $0.005. Pay for that from a separate
// client: this one is capped at $0.005 per payment. GET https://toolvet.app/api/v1/check?url=https%3A%2F%2Fagentstoolshub.com%2Fapi%2Fv1%2Flive%2Fair-quality
const res = await pay("https://agentstoolshub.com/api/v1/live/air-quality?city=Delhi");
console.log(res.status, await res.text());
Python: pay and call
