Tools
| Tool | Description | Behaviour |
|---|---|---|
| calculate_fee_cap | The most a lawyer may charge on one award under a statutory or agency fee limit: Social Security (the lesser of 25% and the current dollar cap), the Federal Tort Claims Act (20% administrative, 25% after suit), VA, workers' compensation sliding scales and medical-malpractice or contingency scales where the dataset has them. Returns the dollar limit, the formula, who approves the fee, the statute or rule with a quote and the day it was read. Rules with no number come back with no figure and say why. Arithmetic on the published limit only. | Read-only |
| check_ad_elements | For one US state or DC and the elements an ad contains (testimonials, results, specialist or expert claims, "no fee unless you win", dramatizations, Spanish or another language, a paid spokesperson, an AI-generated person or voice, comparative claims, a referral or lead service), returns each element's rule text from that state, its status (P/S/D/U), date checked, source and the page section to cite, plus the state's ad filing rule. Optional ad copy is scanned with fixed phrases (for example "best", "expert", "guarantee", "no fee unless we win", dollar amounts) to suggest elements; it is not stored. It flags rules to read and never says an ad passes or fails. Not legal advice. | Read-only |
| cite | The citation sentence, credit line, DOI and URL to cite: for a whole dataset, for one state, or for one rule cell (dataset "rules" with state and topic), or for one record id in another dataset. CC BY 4.0 asks for credit and a link. | Read-only |
| compare_states | One rule topic side by side across several states (or all 50 states and DC when `states` is left out), each with its status, sources and cell URL. Not legal advice. | Read-only |
| data_compare | The records for up to 10 keys of one dataset side by side. Datasets and their keys: benchmarks (table, e.g. AD-CALL-OUTCOMES, CALLS-AND-HOURS, COST-PER-SIGNED-CLIENT, LSA-LEAD-MIX); ca-courts (area, e.g. ALAMEDA, ALPINE, AMADOR, BUTTE); civil-filings (district, e.g. AK, ALM, ALN, ALS); fees (jurisdiction, e.g. AK, AL, AR, AZ); filing (jurisdiction, e.g. AK, AL, AR, AZ); language (area, e.g. 10180, 10420, 10500, 10540); mdl (mdl, e.g. MDL-1358, MDL-1570, MDL-1663, MDL-1720); opinions (jurisdiction, e.g. ABA, AK, AL, AZ); platforms (platform, e.g. CHATGPT-ADS, GOOGLE-ADS, GOOGLE-LSA, LINKEDIN-ADS); referral (jurisdiction, e.g. AK, AL, AR, AZ). Not legal advice. | Read-only |
| data_lookup | The records for one key in one dataset, with sources, status and dates. Datasets and their keys: benchmarks (table, e.g. AD-CALL-OUTCOMES, CALLS-AND-HOURS, COST-PER-SIGNED-CLIENT, LSA-LEAD-MIX); ca-courts (area, e.g. ALAMEDA, ALPINE, AMADOR, BUTTE); civil-filings (district, e.g. AK, ALM, ALN, ALS); fees (jurisdiction, e.g. AK, AL, AR, AZ); filing (jurisdiction, e.g. AK, AL, AR, AZ); language (area, e.g. 10180, 10420, 10500, 10540); mdl (mdl, e.g. MDL-1358, MDL-1570, MDL-1663, MDL-1720); opinions (jurisdiction, e.g. ABA, AK, AL, AZ); platforms (platform, e.g. CHATGPT-ADS, GOOGLE-ADS, GOOGLE-LSA, LINKEDIN-ADS); referral (jurisdiction, e.g. AK, AL, AR, AZ). Not legal advice. | Read-only |
| data_search | Keyword search (deterministic, no model) across benchmarks, ca-courts, civil-filings, fees, filing, language, mdl, opinions, platforms, referral, or only the datasets named. Returns the best-matching records with their dataset, sources and status. For lawyer advertising rules use search_rules. Not legal advice. | Read-only |
| fetch | The full text of one record found with search (ids like rules:TX:filing, opinions:ny-nysba-1306 or benchmarks:speed-to-sign): the rule, opinion, policy, limit or table in plain English, with its status, the day its source was checked, the source URL, the DOI and the page to cite. Not legal advice. | Read-only |
| get_ad_filing_requirements | Whether a state's bar requires lawyers to file or submit ads for review, which ads, when (before or after first use), the standard, expedited and late fees in US dollars, the portal or method, how long to keep copies, and the rule cited. One record per state or DC, read from the state's rules of professional conduct and bar pages, each with its sources and the day they were read. Results summarize public sources for marketing planning; they are not legal advice. | Read-only |
| get_ad_platform_policies | The published advertising policies that apply to law-firm ads on Google Ads, Google Local Services Ads, Microsoft Advertising, Meta (Facebook and Instagram), LinkedIn, YouTube and ChatGPT ads: who may advertise, restricted categories (bail bonds, debt relief, legal services verification), creative, targeting, measurement and billing rules, each quoted from the platform's own policy page with the day it was read. Paginated with cursor. Results summarize public sources for marketing planning; they are not legal advice. | Read-only |
| get_attorney_fee_caps | Statutory and agency limits on what a lawyer may charge: workers' compensation in every state and DC; Social Security (SSDI and SSI), the Federal Tort Claims Act, VA, Longshore and other federal programs (jurisdiction US); medical-malpractice and general contingency-fee rules where read. Each record gives the cap type, percent, dollar cap or sliding scale, what it applies to, who approves the fee, the statute or rule cited with a quote, and the day it was read. A lookup, not a fee calculator. Results summarize public sources for marketing planning; they are not legal advice. | Read-only |
| get_benchmark | Published benchmark tables on law-firm intake and marketing, as bands, tiers and rounded values with the methods page to cite: speed-to-sign (how quickly inquiries become signed clients); calls-and-hours (phone calls and signed-client likelihood); organic-ai (ai answers and organic search clicks); search-click-costs (what law-firm search-ad clicks cost); search-query-patterns (what people type when they search for a lawyer); ad-call-outcomes (what happens to calls from ads); lsa-lead-mix (local services ads: what kind of leads arrive and what gets charged); quarterly-demand (seasonality: inquiries by calendar quarter); cost-per-signed-client (what a signed client costs, by ad channel). Give a table id for its rows, or leave it out for the list of tables. Optional words narrow the rows (for example "same day"). Values are approximate by design. | Read-only |
| get_ca_court_filings | Cases filed in one California county's superior court (or CA for the whole state) in fiscal year 2024-25, by case type: civil (including motor-vehicle injury and other injury and wrongful death), criminal, family, juvenile, probate, mental health and appeals, each with the prior year and the Judicial Council of California Court Statistics Report table it came from. Counts are cases, not people or clients. Results summarize public sources for marketing planning; they are not legal advice. | Read-only |
| get_rule | One state's rule on one topic: the plain-English text, status (P/S/D/U), note, sources with dates, the cell URL and a one-sentence citation. Not legal advice. | Read-only |
| get_spanish_demand_supply | For one US state, DC, the US, or a metro area: people aged 5 and over, Spanish speakers, Spanish speakers who speak English less than very well, employed lawyers, Spanish-speaking lawyers, and how many Spanish speakers with limited English there are per Spanish-speaking lawyer. U.S. Census Bureau American Community Survey 5-year estimates, each with its margin of error, table and reliability flag. Results summarize public sources for marketing planning; they are not legal advice. | Read-only |
| get_state_rules | Every lawyer advertising rule we track for one US state or DC (ad filing, required content, waiting periods, claims and testimonials, referral and lead rules, other languages, call recording, texting law, privacy law), each with its plain-English text, status (P primary source, S secondary, D ABA model default, U open question), sources with the days they were read, and the state page URL to cite. Not legal advice. | Read-only |
| list_datasets | Every public dataset on this server: what it covers, its version, DOI, license (CC BY 4.0), credit line, last-checked date, the page to cite, its files and its tools. | Read-only |
| list_mdl_dockets | Federal multidistrict litigation (MDL) dockets from the Judicial Panel on Multidistrict Litigation's monthly pending-dockets reports, largest first: the docket number, title, court district, actions pending on the report date, total actions, and the change over the past year. Filter by words in the title (for example "hair relaxer" or "talcum") or ask for one docket (MDL-2738) to get its monthly history since 2019. Counts are court actions, not people. Paginated with cursor. Results summarize public sources for marketing planning; they are not legal advice. | Read-only |
| list_rule_changes | Confirmed changes to the lawyer advertising rules dataset, newest first, each with its date, state, the cells it touched and its primary source. Optional `since` (YYYY-MM-DD). | Read-only |
| search | Finds records about US lawyer advertising rules by state, bar ad filing, ethics opinions on lawyer marketing, ad-platform policies for law firms, attorney fee caps, federal MDL dockets, Spanish-language legal demand, California court filings and law-firm marketing benchmarks. Returns up to 10 results, each an id, title and URL; pass an id to fetch for the full text with its source. Deterministic keyword ranking, no model. | Read-only |
| search_ethics_opinions | Ethics opinions from the ABA and state bars on lawyer marketing: lead generators and pay-per-lead, fee sharing, online reviews, lawyer platforms, trade names, solicitation, social media, testimonials, AI tools and more. Each record gives the issuing body, opinion number, date issued, whether it is still in force, its holding in plain words, the rules it applies, what to do, and a link to the opinion. Filter by state, topic or words; newest first within equal matches. Paginated with cursor. Results summarize public sources for marketing planning; they are not legal advice. | Read-only |
| search_rules | Keyword search over every rule cell. States (names, or capitalized codes like TX) and topics (filing, disclaimer, waiting period, testimonials, referral, Spanish, recording, texting, privacy) named in the query narrow the results. Deterministic keyword matching, no AI. Returns the best-matching cells with sources. Not legal advice. | Read-only |
| whats_new | Confirmed changes across the datasets, newest first, each with its date, what changed and its source. Optional `since` (YYYY-MM-DD) and `datasets` filter. | Read-only |
