Spaceflight News API
Latest space news — articles and blog posts about rockets, launches, missions and astronomy, aggregated from dozens of sources (SpaceNews, NASA, ESA, Spaceflight Now and more). Search the archive by keyword or fetch a single article. Great for space dashboards, newsletters, aggregators and education apps.

Meteorites API
NASA's catalogue of 45,000+ meteorites recovered on Earth as an API. For each meteorite: its name, NASA id, classification (recclass, e.g. L5, Iron), mass in grams, whether it was seen to fall or simply found, the year, and the latitude/longitude where it was recovered. Look one up by name or id, find the meteorites NEAR any coordinate (great-circle distance), rank by mass or year, list a classification or year, or search. Great for space, education, mapping and museum apps. Distinct from asteroids and close-approach data — these are rocks already on the ground.

Orbital Mechanics API
Orbital-mechanics maths as an API, computed locally and deterministically. The circular endpoint computes a circular orbit around a body — the orbital speed v = √(GM/r), the orbital period T = 2π·√(r³/GM), the escape speed and the specific orbital energy — from a built-in body (Sun, Mercury through Neptune, the Moon) and an altitude above its surface, or from an explicit orbital radius, central mass or standard gravitational parameter. The escape endpoint gives the escape velocity √(2·GM/r) at any radius or altitude, which is √2 times the circular-orbit speed there. The period endpoint applies Kepler's third law in both directions: from a semi-major axis it returns the orbital period, and from a period it returns the semi-major axis — so a sidereal day around Earth gives the geostationary radius of about 42,164 km. Speeds come out in metres and kilometres per second and km/h, distances in metres and kilometres, and periods in seconds, minutes, hours and days. Everything is computed in SI and is instant and private. Ideal for aerospace and satellite tools, space-mission and education apps, astronomy and KSP-style games, and physics calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is orbital mechanics; for live satellite catalogues use a satellites API and for sky positions use an astronomy API.

Asteroid Close Approaches API
Live near-Earth object close approaches as an API, straight from NASA/JPL's Close-Approach Data (CAD) system. List the asteroids and comets passing nearest Earth over the next N days (or look back), with the approach date, miss distance (in astronomical units, lunar distances and kilometres), relative velocity and an estimated diameter from the object's absolute magnitude; or pull the full close-approach history for a specific object (e.g. 99942 Apophis, 101955 Bennu). Ideal for planetary-defense dashboards, astronomy & space apps, education and "asteroid of the week" content.

Frequently asked questions
Quick answers about pricing, quotas, and integration.
How do I get an API key for SpaceX API?
Sign up for free at oanor.com, generate an API key from the developer dashboard, and call SpaceX API with the x-oanor-key header. No credit card needed for the free tier.
What's the rate limit for SpaceX API?
Free tier allows 1 request per second. Paid plans scale up to 50 requests per second on the Mega tier. Hard limits return HTTP 429 above the quota — no surprise overage charges.
How much does SpaceX API cost?
SpaceX API has a free tier with 100 calls / month. Paid plans start at €6.00 / month with higher quotas and faster rate limits.
Can I cancel my subscription anytime?
Yes. Plans are billed monthly and you can cancel anytime from your billing dashboard. No long-term contracts and no cancellation fee.
Is SpaceX API GDPR-compliant?
All requests to SpaceX API go through our EU-based gateway. Your upstream API key never leaves our server and no personal data is shared with the upstream provider beyond the request you send.
