24 tools

• find_limits

  What is the limit for a substance in a place (an effluent, a river, drinking water, soil), as the regulation itself prints it? Numeric limits and guidelines for one substance or measure, read from the regulations themselves (US federal effluent guidelines, the rules of 31 states…

• check_value

  Is a measured value over the limits we hold? Give a parameter, a number and its unit (and a place, medium or statistic to narrow). Every row find_limits would return comes back with a verdict: over, within, under (below a floor or a band's bottom), or not_comparable with a `why`…

• check_values

  Which results in a lab table are over the limit? A lab table in one call: up to 200 rows of parameter, value and unit, checked against the limits held for one place (and a medium or statistic). Each row is answered by check_value itself: its verdicts (over, within, under…

• read_certificate

  What does a laboratory certificate report, and is any result over the limit? The rows a laboratory certificate prints, read by rules (no AI writes a row): a PDF certificate, or the laboratory's own export as XLSX, XLS or CSV. Each row gives the sample, the parameter, the value…

• verify_claim

  Does a limit we hold say what a claim says? Give the claim as read from a sentence (an AI's answer, a report): parameter, value and unit, and the place, medium and statistic when the sentence gives them. The verdict: confirmed (a held row prints the same number, in that unit or…

• list_sources

  Which regulations, and which editions, does an answer for a place rest on? Every regulation, guideline or permit table we hold for a place: title, issuer, edition, what it governs, how many rows were read from it, and the source URL and sha256. Use it to say what an answer was…

• get_permit

  What are a US facility's discharge permit limits, when is its renewal due, and has it gone over a limit lately? One US NPDES discharge permit as EPA's national file (ECHO / ICIS-NPDES) holds it: facility, place, every limit by outfall, parameter, statistic and months, the…

• list_permits

  Which facilities in a US state hold a discharge permit, which of them are in one industry (paper mills, meat packing, sewage treatment), which went over a limit lately or face a renewal, and which must meet a new or tighter limit already written into their permit? The state's…

• check_dmr

  Will EPA flag this period's Discharge Monitoring Report (DMR)? A US NPDES permit's Discharge Monitoring Report for one period, checked before it is filed: each value you send (outfall, parameter, statistic, value, unit) is set beside the permit's own limit for that period, from…

• fill_dmr

  What numbers go on a permit's DMR this period, computed from the plant's own daily results? The numbers a US NPDES permit's Discharge Monitoring Report asks for in one period, computed from the plant's own raw results (daily samples, flows): for each value due on the period's…

• map_to_darwin_core

  Which Darwin Core term does each column of a species file map to, before it goes to GBIF? Which Darwin Core term each column of a species occurrence or checklist file maps to, by the header rules our file-to-archive converter runs before it checks values: for each column the…

• find_designations

  Is a species protected or at risk, and under which act, list and edition? What the species registers we hold say about one species: its status under each list that names it (the US Endangered Species Act lists, Canada's Species at Risk Act and COSEWIC, provincial acts, the IUCN…

• screen_species

  Which species on a list are protected or at risk? A species list in one call: up to 500 names, each answered by find_designations itself, for one place or everywhere: its designations with their cites and the registers searched that are `silent` on it with what each one's…

• cite_document

  A public document sent here is kept in our library, to be indexed and read into cited rows; a link on a file-sharing host or carrying a signature or token is read and never kept (`kept` says which, and why). Cite numbers or phrases from a public document by page: give its…

• build_dwc_archive

  A file this tool reads, sent or fetched from the address given, is read as one dropped on our website: what the read finds (column headings, the shape of its rows, the terms they became, refusal codes) is kept so the reader learns, never the file or its values. Names and…

• audit_archive

  A file this tool reads, sent or fetched from the address given, is read as one dropped on our website: what the read finds (column headings, the shape of its rows, the terms they became, refusal codes) is kept so the reader learns, never the file or its values. Names and…

• screen_exposure

  Do these occurrence records publish where a listed species lives too precisely? Occurrence records in one call, up to 5000: each record's species name and coordinates as published, optionally coordinateUncertaintyInMeters, a place, and what the file declares about the point…

• export_limits

  Every limit and guideline held for one place and the places above it (CA-QC brings Canada's too, US-OH the US's), as one table: each row with its value, unit, statistic and conditions, and its instrument, edition, section or page, quote, source address and sha256, and what the…

• search

  Search everything this server holds by free text: a substance and a place (copper effluent Québec, ammonia Ohio, a CAS number), a species and a place (Myotis lucifugus Ontario, little brown myotis), an instrument's title (Metal and Diamond Mining Effluent Regulations, 40 CFR…

• fetch

  One document search returned, as text: limits/<place>/<parameter> = every cited row for that parameter there (value, unit, statistic, conditions, and each row's instrument, edition, section or page, quoted text and source URL), and limits/<place>/<parameter>/<medium> the rows of…

• list_sites

  The sites of the signed-in account: id, name, status, when made, and how many documents each holds and how many of them are read. A site holds a project's documents (permits, studies, lab reports, tables); ask_site answers a question from them, cited to the page.

• create_site

  A new site in the account, with its name only: it is placed on a map later, on its page. Each call makes one more site, so look for the site with list_sites first.

• add_document

  One file held on a site and read, as a file dropped on the site's page is: its text layer page by page, its summary and, for a laboratory table, its result rows, all kept in the account and searched by ask_site. Give the file as `content_base64`, or a text as `text`. The same…

• ask_site

  What do a project's own documents say about a question, cited to the page? A question answered from one site's own read documents, by Claude, and checked before it is shown: every statement carries quotes, each quote is found again on the page it names, and a statement whose…
