name: artsonia-api description: >- Access Artsonia (artsonia.com) student-art portfolios, comments, fans, teacher feedback, and downloads from a shell with curl instead of running the artsonia-mcp server — log in with a username/password form POST to get a session cookie, then curl the server-rendered member pages. Use when you want Artsonia data without the MCP, in a script, or on a machine where the MCP isn't installed.

Artsonia via curl (no MCP)

Artsonia is a classic server-rendered .asp site — no public API, no JSON store, no bot wall. All the data (students, portfolios, comments, fans, feedback, awards, profile) lives in server-rendered HTML, and auth is a real username + password form POST that hands back an HttpOnly session cookie. No browser, no Transporter extension, no fpx bridge is needed — curl with a cookie jar reaches everything a signed-in parent account can. (The MCP keeps @fetchproxy/server as an optional fallback transport for some future walled endpoint, but nothing documented here needs it.)

This is the same data the artsonia_* MCP tools return, reached with curl instead of a running server.

One-time setup

export ARTSONIA_USERNAME=you@example.com
export ARTSONIA_PASSWORD='your-password'   # or: op read "op://Private/Artsonia/password"
JAR=~/.cache/artsonia-cookies.txt
mkdir -p ~/.cache   # ensure the jar's directory exists on a fresh box
: > "$JAR"   # fresh jar

Log in (get the session cookie)

Read the password from stdin (Password@-) instead of putting it on the command line — --data-urlencode name=value puts value in curl's argv, which any local user can read via ps//proc while the process runs. This mirrors how the MCP itself sends the password: only in the POST body, never on a command line.

printf '%s' "$ARTSONIA_PASSWORD" | curl -s -c "$JAR" -b "$JAR" -L \
  --data-urlencode "Username=$ARTSONIA_USERNAME" \
  --data-urlencode "Password@-" \
  --data-urlencode "TargetUrl=/members/" \
  --data-urlencode "Action=login" \
  -o /tmp/artsonia-login.html -w '%{http_code} %{url_effective}\n' \
  https://www.artsonia.com/members/login.asp

A successful login redirects away from login.asp (final URL ends in .../members/) and leaves cookies in $JAR. If url_effective still ends in login.asp, or /tmp/artsonia-login.html matches You need to log in|Parent \(or Fan\) Login, the credentials are wrong — Artsonia has no CSRF/__VIEWSTATE token, so a bad login is the only reason this fails. Magic-link-only accounts can't use this (there's no password to POST).

Re-run this exact command any time a later request looks logged-out (see "Session expiry" below) — curl -c overwrites the jar with a fresh session.

Core call pattern

Every read is a GET through the jar; every write is a form-urlencoded POST through the jar. Fetch to a file, then extract:

curl -s -b "$JAR" -c "$JAR" 'https://www.artsonia.com/members/' -o /tmp/dash.html

For the numeric ids every other endpoint needs (artist_id, artwork_id), a plain regex on the href is enough and needs no extra tooling:

grep -oP '(?<=portfolio\.asp\?id=)\d+' /tmp/dash.html | sort -u

For the full structured fields (name, school, stats, notifications, awards, …) don't re-derive selectors by hand — this repo already ships a live-verified node-html-parser scraper (src/parse.ts → built dist/parse.js) with one function per page. Build it once, then import it in a one-liner and pipe the JSON to jq:

cd ~/git/artsonia-mcp && npm install && npm run build   # once, if dist/ is missing
node --input-type=module -e "
import { readFileSync } from 'node:fs';
import { parseStudents } from '$(pwd)/dist/parse.js';
console.log(JSON.stringify(parseStudents(readFileSync('/tmp/dash.html', 'utf8'))));
" | jq '.'

references/endpoints.md has the ready-to-run curl command, dist/parse.js import, and jq projection for every read and write tool, keyed to the same paths and selectors the MCP uses.

The one rule: resolve artist_id (and artwork_id) first

Every per-student/per-artwork endpoint needs a numeric id you can only get from a parent call — never guess one:

1. GET /members/ → .artist-card → artist_id (from each card's portfolio.asp?id= link).
2. GET /artists/portfolio.asp?id=<artist_id> → .grid-item that contains an art.asp link → artwork_id.

Session expiry

Artsonia expires a session by redirecting/rendering back to the login page, not a 401. After any GET/POST, check the response body:

grep -qE 'login\.asp|You need to log in|Parent \(or Fan\) Login' /tmp/out.html \
  && echo "EXPIRED — re-run the login step"

Writes — real caveats from the MCP build

• A 3xx is not proof a write persisted. Artsonia's form handlers 302 even on payloads they silently drop. Re-GET the page you just changed and confirm the field actually flipped before trusting a write.
• Checkboxes submit value=Y, never on. Sending Field=on is silently ignored by the server (still 302s, saves nothing).
• The profile form is read-modify-write. /members/profile/ (#TheForm) bundles name/email/password/opt-ins in one form — re-POST every current field verbatim (blank the password fields, keep DidChangePassword=N), flipping only the one you're changing.
• Never POST a password. Leave OldPassword/NewPassword/ NewPassword2 blank/omitted.

See references/endpoints.md for the exact body of every write, and how to re-read and verify each one.

Artwork images (no auth needed)

Full-resolution images live on a public CDN — no cookie required, even for private pieces:

curl -s -o "$artwork_id.jpg" "https://images.artsonia.com/art/full/$artwork_id.jpg"
curl -sI "https://images.artsonia.com/art/full/$artwork_id.jpg" | grep -i last-modified   # per-artwork upload date

Resolutions (small→large): small medium large xlarge full.

Notes

• Reads/writes both go through the member site (www.artsonia.com); nothing here needs the fetchproxy/browser-bridge path the MCP keeps as an optional fallback.
• Comment-item markup on /museum/art.asp is unverified upstream (both captured accounts had 0 comments) — references/endpoints.md flags it.
• This project is developed and maintained by AI (Claude).
