distill
Registry code: e244c2557fd4848b
Distill sells pre-computed answers to narrow factual questions to AI agents, per call, over x402 (HTTP 402 and a USDC payment on Base). Every answer carries its sources, an as_of time, a computed confidence and the method version that produced it. No account, API key or signup.
Paid tools follow x402 over MCP. An unpaid call to a tool with a free tier gets a free, capped answer while the day's free calls last (_meta["distill/free-remaining"] says how many are left); send _meta["distill/free-tier"]: "skip" to pay for the full answer instead. Otherwise a call without payment returns isError with…

- Is distill live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is distill free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does distill have?
- 7 tools: hospital_payers, tax_sales_rate, tax_sales_rate_batch, hospital_prices, hospital_compare, hospital_changes, tax_changes.
- Is distill safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
hospital_changes open 1h ago
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.

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).

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.

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.

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.

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.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
