TL;DR you can POST a blueprint string directly to /paste.

`GET /`

The text/html landing page, with a webform which accepts a space platform blueprint by sending a POST to /paste.

`POST /paste`

This endpoint accepts pasted blueprints strings.

The body can be one of two forms:

A blueprint string, or
A webform body of the form blueprint=:encoded-bp where :encoded-bp is the percent-encoded blueprint string.

It will respond with a 302 with a Location of /:md5, where :md5 is the MD5 sum of the blueprint string.

`GET /:md5`

The text/html page with the rocket plan for a blueprint.

`GET /:md5/:md5.md`

The Markdown version of a rocket plan, returned as text/plain.

`GET /:md5/:md5.json`

The JSON representation of a rocket plan, returned as application/json.

`GET /:md5/:md5-book.txt`

The rocket plan as a construction blueprint book (using a silo loader), returned as text/plain.

`GET /:md5/:md5-silos-p1-p1-p1-s3l.txt`

The rocket plan as a construction blueprint book (using pre-filled silos), returned as text/plain.
Silo modules may be suffixed, using types 'p', 's', 'e', levels '1', '2', '3' and quality 'u', 'r', 'e', 'l' (legendary speed 3 would be 's3l').

`GET /icons-32/:slug.png`

The 32x32px icon for a given item slug (e.g. fast-inserter), returned as image/png.

`GET /icons-64/:slug.png`

The 64x64px icon for a given item slug (e.g. fast-inserter), returned as image/png (for Retina/HiDPI displays).

`GET /recent`

A text/html page which lists all of the blueprints, sorted by submission date.

`GET /about`

This page.

`GET /weights.json`

An application/json table of all item slugs and weights known by rocketcal.cc (in kg).

`GET /200`

Returns the text/plain response "OK", which verifies the site is still up.

Fixed a bug with modules of non-normal quality (thanks WhiteWhistle).

2025/7/29 tue

Added blueprint book using silos with pre-filled ghosted inventory items (/:md5/:md5-silos.txt) (thanks Zulan!).
Silo modules are specified via the URL (e.g. /:md5/:md5-silos-p1-p1-p1-s1.txt).

2025/1/9 sat

Fixed a bug where small blueprints could cause the tiles under the hub to not be populated in the auto-launch blueprint, which would result in a superfluous rocket launch (thanks Zulan!).

2024/12/14 sat

Fixed a bug in rockets which have an item of both quality and non-quality (thanks Deltaqyto!).

2024/12/11 wed

Added launch count and tags to /recent.

2024/12/10 tue

Fixed a foundation counting bug in the auto blueprint (thanks again DOSorDIE4Csp!). Regenerated all rocket manifests.

2024/12/7 sun

A separate "Auto launches" blueprint is generated which contains all items which fill whole rockets, minimizing the number of manual launches required.

2024/12/6 sat

Space platform foundations are now part of a separate blueprint which uses auto requests for construction.

2024/11/23 sat

Added construction blueprint book generation (/:md5/:md5-book.txt).
Tolerate trailing spaces and newlines when pasting a blueprint.
Fixed another module counting bug. Regenerated all rocket manifests.

2024/11/22 fri

Fixed that modules were missing (thanks DOSorDIE!). Regenerated all rocket manifests.
Added /:md5/:md5.json.
Added 2x icons to support Retina/HiDPI displays.

2024/11/18 mon

Added support for quality.
Fixed an off-by-one error (introduced by yesterday's performance improvements) which dropped the last item of the manifest. Regenerated all rocket manifests.

2024/11/17 sun

Fixed a weight parsing bug (thanks DOSorDIE!). Regenerated all rocket manifests.
Performance fix which reduced Lucrehulk processing time from 18 seconds to 330ms.

2024/11/11 mon

Added icons.
Added about.
Added weights.json.
Added support for Accept-Encoding: gzip.
