|---|---|---|
| Free tier | Limited / trial-based | 1,000 requests / month free trial Free trial |
| Entry paid plan | Enterprise / quote-based | $19 / mo · 5,000 requests Transparent |
| Real-time flight tracking | Yes — strong global coverage | Yes — ADS-B, ~5 s updates |
| True ADS-B positions | Yes — within its platform/API terms | Yes — ICAO24 hex, bounding-box queries |
| METAR / TAF weather | Not a core API offering | Yes — decoded, US & international |
| Airport database | Airport pages, limited API depth | Full ICAO/IATA, runways & frequencies |
| ML flight-time & FAA delays | Not available | ML flight-time + live FAA delay status (US) |
| MCP server for AI | Not available | Yes — native MCP server |
| Historical data | Yes — enterprise tiers | Up to 365 days (90 d Pro, 365 d Business) |

Beyond flight status
Where SkyLink API goes further
Beyond live tracking, SkyLink ships the rest of the aviation stack developers need — natively, behind one key.
True ADS-B, ~5-second updates
SkyLink reads raw ADS-B receiver data — ICAO24 hex, callsign, latitude, longitude, altitude, ground speed and track — sampled roughly every 5 seconds, with bounding-box queries for any map viewport.
Decoded METAR & TAF weather
Fully decoded METAR observations and TAF forecasts across US and international airfields — wind, QNH, visibility, cloud layers, temperature and dew point — alongside live flight data.
Complete airport & navaid database
Search 74,000+ airports by ICAO, IATA, city, location or IP, with runways, frequencies, navaids (VOR, NDB, ILS) and elevation.
ML flight-time, FAA delays & carbon
An ML gate-to-gate flight-time model, a real-time FAA delay-status feed, and ICAO-based carbon estimates — all behind one key.

Flightradar24 vs SkyLink API: common questions
Flightradar24 is a leading flight-tracking product with an API geared to its own platform and enterprise agreements. SkyLink is a developer-first aviation data API: true ADS-B plus weather, airports, navaids, charts and ML predictions, with self-serve pricing and no sales process.
Flightradar24: Enterprise / quote-based. SkyLink API: $19 / mo · 5,000 requests. Free access — Flightradar24: Limited / trial-based; SkyLink API: 1,000 requests / month free trial. Every SkyLink plan includes all data endpoints and paid plans include a commercial licence.
Flightradar24: Yes — within its platform/API terms. SkyLink API: Yes — ICAO24 hex, bounding-box queries, refreshed roughly every 5 seconds.
Flightradar24: Not a core API offering. SkyLink API: Yes — decoded, US & international, on the same API key as flight data.
Get an API key, run SkyLink alongside your current provider while you map response fields using the API reference, then move traffic over. Official SDKs for Python, Node.js and Go keep the change small, and paid plans include a key immediately after checkout.
