Clusters earthquakes that are close in space and time into sequences, using a single-link approach with an explicit distance and time threshold that both appear in the result. For each sequence you get the strongest event, the events that preceded it and those that followed, the duration, the spatial extent, the magnitude range and the rate of events per day. The naming is deliberate: the fields are before_strongest and after_strongest, not foreshocks and aftershocks.

Answers whether a drug carries a boxed warning, the strongest warning class the FDA applies, and returns the warning text with the label version it came from. The check runs across multiple labels for the same substance rather than the first hit, because labels are maintained independently by each manufacturer and the same generic can carry a boxed warning at one and not at another; taking the first result and answering no is how this question gets answered wrongly.

Searches the FDA enforcement database for drug recalls matching a product name, company or date range and returns each with the classification leading: class one means use can cause serious harm or death, class three means it will not, and a recall for a wrong label colour and one for contamination share only the word. The class is therefore returned with its meaning spelled out rather than as a bare code.

Retrieves the earthquakes within a radius and time window of a point and turns them into an exposure figure. Each event contributes according to its magnitude and its distance, using an explicit formula that is returned with the result: energy scales exponentially with magnitude and attenuates with distance, so a distant large event and a near small one can contribute comparably, which is the behaviour that makes a single count useless.

Returns the ingredient list of a product as a structured hierarchy including sub-ingredients, with each additive resolved to its E number and name, the percentage where declared, and the origin markers such as palm oil or vegan and vegetarian status as the record carries them.
