Science And Education x402 offerings

Veteran education benefits guide for veteran and VA-benefits agents. Compares the US GI Bill (housing allowance calculator, VR&E eligibility, dependent transfer) against the closest UK (ELC/SLC), Canadian (VAC ETB), Australian (DVA), New Zealand, and German (BFD) education/training equivalents.

Vocabulary From a Text — Builds a vocabulary list for a language learner from one pasted text, as strict JSON: for every word the learner should learn it gives the form as written in the text, the dictionary form, a translation in the sense the text uses and the whole sentence of the text as the example sentence, copied word for word. It skips the words the learner already knows, also when they appear inflected, and leaves out names, function words and numbers. Dictionary forms follow the conve…

Is this address safe to pay? Screen a wallet address before you pay or send funds to it: an OFAC SDN sanctions check of the address plus address reputation (drainer, phishing, mixer, money laundering) for EVM and Solana. Returns one verdict to branch on (allow, review, or block) with a 0-100 risk score and per-signal evidence. AML / KYT counterparty check for x402 payments. $0.005 USDC.

Google Scholar academic search. Returns papers with snippets, publication info, and citation counts.

Fit y = intercept + slope*x to 2–64 declared pairs using positive weights and exact rational normal equations. Returns residuals and weighted SSE rounded to 12 decimal places, plus finite float64 RMSE. Rejects degenerate X values; weights are not verified uncertainties. Not field certification.

Use when an agent runs something daily and everyone must get the same thing that day: the word of the day with its definition, part of speech and an example sentence, in English or Spanish. Genuinely of the day: it is picked deterministically from the UTC date, so everyone gets the same word and you can reproduce any past day by passing it. The usual endpoints just return a random word and call it the word of the day.

Get today's curated Word of the Day (definition + part of speech).

Extract supported metrics from bounded supplied stress-strain data under a declared method. Report fit and sampling limits; no structural design approval.

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 squ…

Match supplied reference and sample peak lists under declared tolerances. For spectrum-data comparison; no unique compound identification from peaks alone.

Check one structured public or synthetic low-stakes experiment plan for timing, comparator, outcome and analysis declarations. Returns deficiencies and an integrity receipt. No registration, trusted …

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

Calculate X, Y and Z Pauli expectations for a supplied valid single-qubit density matrix. Returns basis conventions; not a hardware measurement. New modular adapter: retained result recovery for 24 h…
