This server accepts AION 2 combat logs in a2log, an open JSON format. Any meter, parser or bot can upload a fight with one HTTP request and get back a link anyone can open.

Discovery	https://island-1.tailbe3340.ts.net/.well-known/a2log.json
JSON Schema	https://island-1.tailbe3340.ts.net/schema/a2log-v1.json
Upload	POST https://island-1.tailbe3340.ts.net/api/v1/logs
Auth	Authorization: Bearer <key> (ask the server owner for a key; anonymous uploads are not allowed)
Body	one a2log document, Content-Type: application/json, optionally Content-Encoding: gzip; at most 25 MB
Visibility	?visibility=public|unlisted|private or meta.visibility; default unlisted (link only). Public logs are listed on the home page; private links carry a secret ?t= token.

One document is one fight: players, and one or more segments (pulls). Times are seconds from the segment start. Only t, player and damage are required per hit; add what your tool knows.

Field	Meaning
players[].class	gladiator, templar, assassin, ranger, sorcerer, spiritmaster (or elementalist), cleric, chanter
players[].specs	skill name → chosen specialization slots 1-5
players[].stats	optional: the character's stats during the fight as the game shows them (critical_hit, attack, double_pct, perfect_pct, multihit_pct, combat_speed_pct, cooldown_pct, accuracy); lets the server calibrate crit and the other rates
meta.contribute	"no" keeps the fight out of the anonymous class statistics (private logs are always kept out)
hits[].skill_id	the game's skill id; variant codes are fine (the viewer maps them to the class skill)
hits[].multi	extra hits of a multi-hit (0 = none)
hits[].step	name of a chain follow-up (e.g. "Cold Wave" with Ice Chain's id)
segments[].hp	boss HP samples [t, hp]

Answer (201):

{"id": "aB3dE5fG7h", "visibility": "unlisted", "url": "https://island-1.tailbe3340.ts.net/l/aB3dE5fG7h",
 "json_url": "https://island-1.tailbe3340.ts.net/api/v1/logs/aB3dE5fG7h/raw", "delete_token": "…", "delete_url": "…"}

import json, urllib.request
req = urllib.request.Request("https://island-1.tailbe3340.ts.net/api/v1/logs", json.dumps(doc).encode(),
                             {"Content-Type": "application/json", "Authorization": "Bearer " + key})
print(json.load(urllib.request.urlopen(req))["url"])

Errors come back as {"error": "…"} with 400 (the document is invalid; the message names the field), 401 (no key), 413 (too large) or 429 (too many uploads).

Read: GET /api/v1/logs (public list), GET /api/v1/logs/<id> (summary), /raw (the document), /analysis?segment=0&player=p1 (breakdown). Delete: DELETE /api/v1/logs/<id>?token=<delete_token> or with the uploader's key.

Learned from all public and unlisted uploads (anonymous): GET /api/v1/stats/<class> (class statistics, also on the statistics page) and GET /api/v1/calibration/<class> (per-skill damage factors, rate factors and crit curve for simulators).
