Distill

Change records from diffing consecutive weekly builds: a hospital republishing its file (source raw_sha256), items and payer rates that appear, disappear or change price, a hospital’s status or file date changing, and the canonical payer of a payer/plan name changing. Keys: source `<source_id>`; hospital `<hospital id>`; item `<source_id>|<type>|<code>|<setting>|<billing_class>|<modifiers>`; rate `<item key>|<payer name>|<plan name>|<methodology>` (names as the hospital writes them; one rate per methodology, empty when none is given); plan `<payer name>|<plan name>`. Money is integer micro-USD (unit usd_micro). Each record cites the sha256 of the file versions it came from. Pages of up to 100, oldest first; pass next_cursor back as cursor. Price: $0.05 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: Change records are diffs of consecutive serving DBs, computed deterministically; confidence is the feed’s freshness only: 1 within 14 days of the newest build, then halving every 30 days. Posted standard charges from hospital machine-readable files (45 CFR 180): posted rates, not a quote; not medical or financial advice. What you pay depends on your plan, your care and the hospital. See /terms.

For each named hospital: whether it posts the code, and over its items for the code (only those without modifiers when it posts any, so a professional -26 or bilateral -50 line does not skew the row) nearest-rank statistics of its gross charges, discounted cash prices and negotiated dollar amounts across payers and plans, the range of negotiated percentages, the de-identified minimum and maximum, and the number of payers. The same filters as hospital.prices. Hospital ids come from hospital.prices (or pass a CMS certification number). Not charged when none of the hospitals is known. Price: $0.02 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: Mean over the returned rows (each rate; an item with no rate counts once) of normalize × quality × freshness. Normalize: the stored per-rate normalize confidence (payer canonicalization: rule 1, model 0.9, fallback 0.6; rate basis for rates with no dollar amount: rule 1, model 0.9, fallback 0.75; 1 for an item with no rate). Quality of the MRF: 1 valid against the v3.0 schema, 0.85 parsed with conformance errors, 0.7 parsed only after header repair. Freshness: 1 while the MRF’s last_updated_on is at most 365 days old, then halving every 180 days (0.5 with no date), times 1 within 14 days of our fetch, then halving every 30 days. Rows are each hospital’s items for the code as compared. Posted standard charges from hospital machine-readable files (45 CFR 180): posted rates, not a quote; not medical or financial advice. What you pay depends on your plan, your care and the hospital. See /terms.

Every payer’s negotiated dollar amounts for the code at the hospitals within the radius, grouped by canonical payer_id (the stable id behind the many ways hospitals write a payer’s name), plan type and methodology (a per diem and a case rate are never pooled): how many hospitals and rates, and nearest-rank statistics. Payers with the most hospitals first. Percentage-only rates are left out (they have no dollar amount; hospital.prices shows them). The payer_ids here are what the payer filter of hospital.prices and hospital.compare takes. Price: $0.02 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: Mean over every rate in the payer rows returned of normalize × quality × freshness, with the same factors as hospital.prices (normalize: the stored per-rate payer canonicalization confidence, rule 1, model 0.9, fallback 0.6; quality: 1 valid v3.0, 0.85 with conformance errors, 0.7 after header repair; freshness: 1 while last_updated_on is at most 365 days old, then halving every 180 days, times 1 within 14 days of our fetch, then halving every 30 days).

See /terms.

From the machine-readable standard-charge files hospitals must publish (45 CFR 180), parsed and normalized: for each hospital within the radius that posts the code, nearest first, the gross charge, the discounted cash price, the de-identified minimum and maximum, and every payer and plan’s negotiated dollar amount or percentage (with the v3.0 median, 10th and 90th percentile allowed amounts), payers canonicalized to a stable payer_id. Filters: payer, plan type, plan name text, setting, billing class. A summary gives nearest-rank statistics over the hospitals returned. Served states: Colorado. An area with no hospital posting the code answers 404 and is not charged. Price: $0.02 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: Mean over the returned rows (each rate; an item with no rate counts once) of normalize × quality × freshness. Normalize: the stored per-rate normalize confidence (payer canonicalization: rule 1, model 0.9, fallback 0.6; rate basis for rates with no dollar amount: rule 1, model 0.9, fallback 0.75; 1 for an item with no rate). Quality of the MRF: 1 valid against the v3.0 schema, 0.85 parsed with conformance errors, 0.7 parsed only after header repair. Freshness: 1 while the MRF’s last_updated_on is at most 365 days old, then halving every 180 days (0.5 with no date), times 1 within 14 days of our fetch, then halving every 30 days.

Change records read from the states’ rate and boundary files: rates that change, begin or end; ZIP+4 and 5-digit ZIP ranges whose jurisdictions change; new files posted. Each record cites the sha256 of the files it came from. Pages of up to 100, oldest first; pass next_cursor back as cursor. Price: $0.05 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: Freshness only (change records are read from the state files deterministically): 1 until the next SST posting deadline (the 1st of Mar, Jun, Sep or Dec) after the files were last checked, then halving every 30 days. Not tax advice. Rates as published by the state in its Streamlined Sales Tax rate and boundary files for the stated effective period; verify with the state. See /terms.

From the state’s own Streamlined Sales Tax rate and boundary files (24 states: AR, GA, IA, IN, KS, KY, MI, MN, NC, ND, NE, NJ, NV, OH, OK, RI, SD, TN, UT, VT, WA, WI, WV, WY). Matches an address when the state publishes address records, else the ZIP+4 record, else the 5-digit record (the lowest rate in the ZIP, per SSUTA 305). Returns each jurisdiction’s rate, the combined rate, and the period it holds. Locations outside these states answer 404 and are not charged. Price: $0.005 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: agreement × freshness. Agreement: for a 5-digit ZIP answer, the share of that ZIP’s ZIP+4 records with the same combined rate; for a ZIP+4 answer, the share of address records inside it with the same rate; 1 for an address match or when the state publishes nothing finer. Freshness: 1 until the next SST posting deadline (the 1st of Mar, Jun, Sep or Dec) after the files were last checked, then halving every 30 days. Not tax advice. Rates as published by the state in its Streamlined Sales Tax rate and boundary files for the stated effective period; verify with the state. See /terms.

The same answer as tax.sales_rate for each location, in order. A location that fails (outside the SST states, a bad date) carries its own error; the call is still one price. Price: $0.1 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer, taken by an unpaid call unless its _meta["distill/free-tier"] is "skip". Confidence: The lowest per-location confidence in the batch; each is agreement × freshness. Agreement: for a 5-digit ZIP answer, the share of that ZIP’s ZIP+4 records with the same combined rate; for a ZIP+4 answer, the share of address records inside it with the same rate; 1 for an address match or when the state publishes nothing finer. Freshness: 1 until the next SST posting deadline (the 1st of Mar, Jun, Sep or Dec) after the files were last checked, then halving every 30 days. Not tax advice.
