Tools of The Durability Curve
	Description		Read-only	Idempotent	Open world
`get_ai_models`Get The Durability Curve's record of AI model releases from ten labs (OpenAI, Anthropic, Google, DeepSeek, Meta, xAI, Mistral, Alibaba, Moonshot, Zhipu): when each model came out, with the lab's own announcement as source; for models with a page, the API list prices read at the lab's pricing page on a stated day; for the frontier launches the Access Gap tracks, when ordinary people could first use it, in the app, on the cheapest paid plan and on the free plan, each with its source; and each lab's flagship price and free-plan answer. Search by model or lab name, or filter by lab, release date, frontier status or free-plan access. The record runs to data_through; a newer release is not in it yet. These tools retrieve The Durability Curve's public material. They do not certify that any claim is true.

`get_claim_ledger`Get the claim ledger for one essay: each load-bearing claim it makes, the source it was checked against, the quoted words, where in the source they appear, the date the source was read, and a status saying how the claim was checked. The response defines every status. Filter by claim ids or status, or ask for compact rows. Claims removed during checking are listed separately under "struck", with the reason; they are not claims the essay makes. Only some essays have a ledger: search results and get_essay link to one when it exists. These tools retrieve The Durability Curve's public material. They do not certify that any claim is true.

`get_essay`Get one Durability Curve essay: by default its full public text as markdown, with its title, dates, canonical field, access, length, sections, tools and a link to its claim ledger when it has one. A long essay can be read in parts: part "outline" lists the sections with their opening lines, part "section" returns one, and part "meta" returns everything but the text. For a part-paid essay only the free part is public, and the text says where it stops. The canonical field is the address to cite. These tools retrieve The Durability Curve's public material.

`get_weekly_calls`Get the calls printed in The Durability Curve Weekly: dated, checkable predictions, each with the confidence printed at the time and the date or event it resolves on. Filter by status, ID, issue, resolution date or printed confidence. The wording is exactly as printed and never changes after publication. outcome is null until a call resolves. counts describe the calls returned; record describes every call.

`related_to`Compare a passage of text (an article, a headline, a draft, a question) with the whole archive and return what The Durability Curve has already published on it, grouped: essays, ledger claims, weekly calls, laws, free tools and AI models. Each result carries its URL and a share: how much of the passage's distinctive vocabulary it uses. possible_repeat is true when an essay (with its best ledger rows) shares at least 45% of that vocabulary: on the live archive it flagged 13 of 21 paragraphs taken from essays and none of 4 unrelated passages. It is a word-overlap signal, not a judgement: whether a topic is covered is in the essay itself. These tools retrieve The Durability Curve's public material.

`search`Search or list the public archive of The Durability Curve: essays on which kinds of work keep their value as AI gets cheaper, the checked claims in each essay's claim ledger, the dated calls printed in The Durability Curve Weekly, the five laws and two derived principles the essays are tested against, the free tools, and AI model releases. With a query, returns ranked matches, each with its kind (essay, claim, call, law, tool or model), a snippet and a URL (canonical for essay citations); "title_matched" says whether any essay title contains every word of the query, and "none_found" is true when nothing matches enough of the query (the nearest misses are then under "closest", not "results"). With an empty query, lists newest first, filtered by kind, series, has_ledger or access, and "total" counts every match. Read a match in full with get_essay, get_claim_ledger, get_weekly_calls or get_ai_models. These tools retrieve The Durability Curve's public material. They do not certify that any claim is true.
