The Landsat Alphabet API renders text as a deterministic PNG stitched from NASA/USGS Landsat letter imagery. It is unofficial and is not endorsed by NASA.

## Quick usage

Embed an image:

<img src="https://landsat.pranavkarra.me/v1/name/PRANAV.png" alt="PRANAV rendered in Landsat imagery" />

Fetch metadata:

fetch("https://landsat.pranavkarra.me/v1/name/PRANAV.json").then((res) => res.json())

## Endpoints

- GET /v1/name/{text}.png
- GET /v1/name/{text}.json
- GET /v1/manifest.json
- GET /openapi.json
- GET /llms.txt

## Parameters

- size: 512 or 1024. Default: 512.

## Agent guidance

Use /v1/name/{text}.png directly in HTML, Markdown, Open Graph image generation, slides, or docs. Use /v1/name/{text}.json when you need selected letter metadata, tile URLs, source URLs, or attribution.

Always include attribution near generated output: Source imagery: NASA/USGS Landsat. Unofficial; not endorsed by NASA.
