What is TianAPI Vehicle Limit Lookup?
TianAPI Vehicle Limit Lookup is an Openclaw Skills package for retrieving city driving restriction data from TianAPI. It supports lookups by city name or city code and returns local-vehicle and out-of-town vehicle restrictions, rule windows, restricted zones, and fine standards in a format that is easy for agents and scripts to consume.
Use it when your workflow needs fast answers about traffic limitations before a route is planned, a trip is confirmed, or a compliance check is performed. Openclaw Skills can call the bundled scripts/fetch_vehiclelimit.py wrapper or hit the REST endpoint directly, making the skill suitable for both automation pipelines and ad-hoc command-line queries.
TianAPI Vehicle Limit Lookup Use Cases
- Checking today’s local and non-local vehicle restrictions before driving into a city.
- Building travel assistants that warn users about tail-number bans, time windows, or zone-specific limits.
- Automating route planning or dispatch decisions for fleets, delivery teams, or field sales reps.
- Verifying whether a city’s restriction policy applies to a vehicle by name or code.
- Embedding Openclaw Skills into CLI workflows that need fast, structured traffic rule lookups.
How TianAPI Vehicle Limit Lookup Works
- The user asks for vehicle restriction information for a city and supplies either a city name or a city code.
- The skill resolves the request parameters and reads the TianAPI key from the configured environment variable,
.envfile, or inline CLI argument. - Openclaw Skills runs
scripts/fetch_vehiclelimit.pyor issues a direct GET request to the TianAPI vehicle limit endpoint. - TianAPI returns structured JSON containing
city,localcar,foreigncar, andlimitinfodata. - The skill formats the response into a concise, readable summary and maps any API error codes to actionable guidance.
- If the request is incomplete or the network fails, the skill surfaces the specific failure state so the caller can retry or correct the input.
TianAPI Vehicle Limit Lookup Setup
- Install prerequisites: ensure Python 3 is available.
python3 --version
Register at TianAPI, apply for the city vehicle limit interface, and copy your API key.
Configure authentication using one of the supported Openclaw Skills patterns:
export TIANAPI_VEHICLELIMIT_KEY=your_api_key
echo "TIANAPI_VEHICLELIMIT_KEY=your_api_key" > scripts/.env
- Run a lookup or test the REST endpoint:
python3 scripts/fetch_vehiclelimit.py your_api_key --city 北京
curl "https://apis.tianapi.com/vehiclelimit/index?key=YOUR_API_KEY&city=北京"
