The National Aeronautics and Space Administration
NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery. The api.nasa.gov portal hosts a federated set of APIs that make NASA imagery, science, and mission data accessible to application developers.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles The National Aeronautics and Space Administration the way a machine reads it — 35 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — The National Aeronautics and Space Administration scores 37.3/100 (thin), with a separate agent-readiness read of 23/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile The National Aeronautics and Space Administration
Each block below is one kind of artifact we hold for The National Aeronautics and Space Administration. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 20
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
APOD - Astronomy Picture of the Day
One of the most popular websites at NASA is the Astronomy Picture of the Day. This API exposes the same featured image with metadata.
NeoWs - Near Earth Object Web Service
Near Earth Object Web Service is a RESTful web service for near earth Asteroid information including closest approach data and orbital data.
DONKI - Space Weather Database Of Notifications, Knowledge, Information
The Space Weather Database Of Notifications, Knowledge, Information (DONKI) is a comprehensive online tool for space weather forecasters, scientists, and researchers.
Earth Imagery and Assets
Earth imagery API providing Landsat 8 imagery and asset metadata for a given lat/lon location and date.
EONET - Earth Observatory Natural Event Tracker
EONET is a prototype web service that provides a curated source of continuously updated natural event metadata.
EPIC - Earth Polychromatic Imaging Camera
The EPIC API provides full disc imagery of the Earth captured by the DSCOVR spacecraft, including natural and enhanced color images.
Mars Rover Photos
Image data gathered by NASA's Curiosity, Opportunity, Perseverance, and Spirit rovers on Mars, accessible through this API.
NASA Image and Video Library
The NASA Image and Video Library API exposes the public NASA media library content including imagery, video, and audio.
TLE - Two Line Element Set
The TLE API provides up to date two line element set records, the standardized format for distributing earth-orbiting object orbital data.
Exoplanet Archive API
Programmatic access to NASA's Exoplanet Archive database of confirmed exoplanets and planet candidates.
InSight - Mars Weather Service
Per-Sol summary data for each of the last seven available Sols (Martian days) from the InSight lander on Mars.
TechPort
RESTful web services to make NASA technology project data available in a machine readable format.
SSD/CNEOS - Solar System Dynamics and Center for Near-Earth Object Studies
Provides access to a number of resources from the Solar System Dynamics group and the Center for Near-Earth Object Studies.
The National Aeronautics and Space Administration APOD API
Astronomy Picture of the Day.
The National Aeronautics and Space Administration DONKI API
Space Weather Database Of Notifications, Knowledge, Information.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
FinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.
Cost, billing, and metering signals for API financial operations.
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
National Aeronautics And Space Administration Domain Security
TLSv1.3 · HSTS · DNSSEC · DMARC
SECURITYAgentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

The organization behind the API
← All providers · Data indexed from github.com/api-evangelist/national-aeronautics-and-space-administration · machine-readable index on apis.io
This is an independent, third-party profile of The National Aeronautics and Space Administration, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
