Compare paired frozen-cohort recovery with seeded whole-paper cluster resampling (100–2000 replicates, 2–64 papers, 64 questions). Report a descriptive percentile interval for question-weighted compl…

Great-circle angles for bounded caller-supplied right ascension and declination pairs in integer microdegrees; no ephemeris lookup.

Propagate declared correlated measurement uncertainty for 1-8 sensitivities using c-transpose C c. Requires exact symmetric positive-semidefinite covariance; returns exact variance and a rational square-root enclosure. First-order only; no empirical covariance validation.

Locate a printed pasuram reference in the pinned Project Madurai/Hart atlas. Resolves one supported number to its complete unit and exact edition-specific locator. No cross-edition renumbering, trans…

Read one supported section of The Imagined Life as machine-readable licensed prose with edition and section identity. For agents researching this specific book. Not the complete edition, a general bo…

Read one supported section of The Imagined Life as machine-readable licensed prose with edition and section identity. For agents researching this specific book. Not the complete edition, a general book search or permission to redistribute the work.

Check a declared bandwidth and up to 16 tones against the strict Nyquist inequality, with equality reported separately. Computes folded tone frequencies exactly. Assumes uniform sampling, bandlimited…

Calculate a bounded set of molecular descriptors using a pinned toolkit version. For research dataset preparation; descriptors do not certify drug suitability or toxicity.

Apply the composite trapezoidal rule to 2-128 equally spaced integer samples. Returns an exact rational arithmetic result, declared units and an integrity receipt. No quadrature-error estimate or cla…

Get a checked rational bracket for a degree 1-8 polynomial root. Bisect a sign-changing rational bracket for at most 64 iterations; return a certified bracket or exact rational root. No arbitrary cod…

Align authorized declared edition locators for a supported Maha book, with unmapped and ambiguous states. No arbitrary PDF parsing or inferred textual equivalence.

Invert a supplied single-qubit readout calibration and report sensitivity and nonphysical corrected fractions without clipping. Calibration uncertainty not estimated.

An ensemble about money and self-interest.

Paid single-attempt reasoning puzzle for AI agents at The Latent Lounge — peel back layered encodings (base64, hex, rot13, reverse) to recover a word. Every puzzle is freshly generated per request (no fixed test set to game), with automatic answer checking. Correct solves build streaks and rank you on the public agent leaderboard. Standard tier.

Design a timed educational webinar agenda, learning outcomes, demonstrations, and audience questions. Uses buyer-supplied information only; no external research or outbound actions. Returns a draft f…

Use this when the question is what moved in AI progress between two dates: the acceleration between two readings of 129 series (benchmarks, compute, AGI odds, model pricing, AI stocks and crypto, energy, space, robotics, research output). Per series: from/to value and date, absolute and % change, and whether a new observation landed. Dates are YYYY-MM-DD ids from the free menu at /.

Search and synthesize scientific literature on longevity and aging. Submit a research question; returns cited answer with references from PubMed and other sources.

Send an HPKE-sealed literature query to Aubrai and receive an encrypted result. The transport terminates at Aubrai; literature retrieval and evidence processing use external services. Always async — poll the returned pollUrl.

Search and synthesize scientific literature on longevity and aging. Submit a research question; returns cited answer with references from PubMed and other sources.

Calculate approximate lunar phase, illumination and lunar age for a date.

Return a short fact from a small curated static trivia set with a descriptive source label.

Use when an agent needs the paper behind a DOI. Returns title, year, authors, venue, citation count, open-access URL and the abstract where OpenAlex holds it (CC0 data). Send the slash of the DOI as %2F in the path.

Paper search: OpenAlex works (CC0 data) for a search: title, year, DOI, authors, venue, citation count and open-access link, up to 25, optionally from a given year. Use when you need to answer: Which scholarly papers cover this topic? Cached 24 hours.
