LopoRail Public API

Quickstart

# Your key looks like:
lra_abcdefghijklmnopqrstuvwxyz123456

curl -H "Authorization: Bearer lra_abcdefghijklmnopqrstuvwxyz123456" \
  "https://loporail.com/wp-json/loporail/v1/stations?search=kings+cross&limit=5"

const res = await fetch('https://loporail.com/wp-json/loporail/v1/stations?search=kings+cross&limit=5', {
  headers: { Authorization: 'Bearer lra_abcdefghijklmnopqrstuvwxyz123456' },
});
const data = await res.json();
console.log(data);

r = requests.get(
    'https://loporail.com/wp-json/loporail/v1/stations',
    params={'search': 'kings cross', 'limit': 5},
    headers={'Authorization': 'Bearer lra_abcdefghijklmnopqrstuvwxyz123456'},
)
print(r.json())

$res = wp_remote_get( 'https://loporail.com/wp-json/loporail/v1/stations?search=kings+cross&limit=5', array(
    'headers' => array( 'Authorization' => 'Bearer lra_abcdefghijklmnopqrstuvwxyz123456' ),
) );
$data = json_decode( wp_remote_retrieve_body( $res ), true );

Rate Limits

API keys have tier-based limits:

The Free tier covers /stations, /boards, /info. Live /ppm and /positions require the Developer tier or higher. Free and Developer keys must show a "Powered by LopoRail" link; Business and Enterprise may white-label. See plans

Rate Limit Headers

Every response includes headers to help you manage your quota:

• X-RateLimit-Limit-Day — Daily limit
• X-RateLimit-Remaining-Day — Requests remaining today
• X-RateLimit-Limit-Month — Monthly limit
• X-RateLimit-Remaining-Month — Requests remaining this month
• X-RateLimit-Reset-Day — Unix timestamp when daily limit resets
• X-RateLimit-Reset-Month — Unix timestamp when monthly limit resets

Exceeding Limits

When you exceed a limit, the API returns 429 Too Many Requests with a Retry-After header indicating seconds until reset.

Live data demo

A real departures board, rendered server-side from the same feed the API serves. No key needed for this sample.
