Certopolis

What Certopolis is, how the game works, the public pages of the site, how to connect it to Claude, and how many questions are live. No sign-in needed.

Submit the player's answer to a dealt question. Returns whether it was right, the key, the explanation, the Renown change and the building's new level.

Submit the player's answer to a review question. Returns right/wrong, the key, the explanation and the retire streak.

Deal a batch of practice questions for one domain (building) at the player's current tier. Returns a batchId and the questions WITHOUT answers.

Deal missed questions to retry, WITHOUT answers. Reviews pay no Renown; enough correct in a row retires a miss. Optionally limit to one domain.

Close a batch and get its summary: answered, right, wrong, looked up, Renown gained and levels moved.

The public board of what players have asked for: open requests ranked by votes, what is planned, what has shipped, and what will not be done. No sign-in needed; voting and suggesting happen on the page.

One town's public page: its rank, % built, biome, each district with its buildings' levels, its hat tips, and whether it is a bot (a settlement of the realm, not a player's city). Course and domain names are never public. No sign-in needed.

A region's capital (a landmark that belongs to nobody): its name, biome, cell and its wards. No sign-in needed.

One /learn concept page in full: the answer, each section, the exam traps, the vendor docs it is drawn from, related topics and its practice questions (with keys: reveal after the person picks). No sign-in needed.

Questions the player got wrong and has not yet retired by reviewing them correctly, newest first.

One region as its map shows it: every town with its cell (axial q, r), rank, % built, biome, whether it settled this week and its page; the capital; and the open sites a newcomer can settle on, each with its biome. No sign-in needed.

The free questions anyone can try on the site for one exam (the landing page's run and the /learn hub's sampler), WITH the key and every option's explanation. Show the stem and options first and reveal the key only after the person picks. No sign-in needed.

How ready the player is for the exam: per-domain Renown, accuracy over recent answers, questions seen versus bank size, misses, days to the exam and pace.

The player's current exam and town: one building per exam domain with its domainId, level, Renown, current question tier and the bands available, plus how many misses await review.

Everything the bank teaches about a question the player has already answered or looked up: the stem, options, key, the player's pick, the explanation, why each wrong option is wrong, the longer teaching note and the concept map. Pays and changes nothing.

Every certification exam on offer, which one is current, and the player's progress in each.

Every certification exam with a live question bank: vendor, name and code, how many questions, the real exam's format, and each domain with the vendor's weight and the bank's share. No sign-in needed.

The /learn concept pages: for each exam, its domains and every topic explained there (title, one-line description, page). No sign-in needed.

The themes a town can wear (the /looks gallery): name, what it looks like, its data cost and its full-screen viewer; plus every biome a town can stand on. No sign-in needed.

Every region of the world map, each with its towns (name, settlement rank, % built, the ground or biome it stands on, and its page), its capital, and a count of towns per biome. No sign-in needed.

Reveal the key and explanation for a dealt question WITHOUT answering it. Pays no Renown and parks the question for a while.

Set the date of the player's exam for the current course (YYYY-MM-DD), or null to clear it.

Make another exam the player's current course. Progress in every course is kept.
