Current US notifiable-disease surveillance from the CDC NNDSS (National Notifiable Diseases Surveillance System) weekly tables. Returns provisional weekly case counts for ~139 nationally notifiable conditions (e.g. Measles, Pertussis, Mumps, Hepatitis A, Lyme disease, Gonorrhea, West Nile, Dengue) by reporting area and MMWR week, updated weekly. Filter by condition (substring, case-insensitive: "measles" matches "Measles, Indigenous"), location (a reporting area: a US state full name like "California", "New York City", "U.S. Residents", a census region like "Pacific", or a territory), year (MMWR year, 2022 to current), and weeks (most-recent N observations). At least one of condition or location is required. Each record reports the current-week count, the previous-52-week maximum, cumulative cases YTD this MMWR year, and cumulative YTD the prior year for same-week comparison. Public-domain CDC federal data via data.cdc.gov. Use this to see live disease activity and outbreaks that postdate an agent's training cutoff.

Provider

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Hand this page to an agent

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.

GET api.roundhouseai.io/v0/endpoints

No per-endpoint history for this service yet, so this is payments indexed to its PROVIDER's wallet over 30 days. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service 2s and tell me whether it is
worth paying: what a call costs, whether the endpoint answered when last probed, and what
its payment record actually shows.

curl -s 'https://api.roundhouseai.io/v0/endpoints?q=2s'
curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>'

Then call it: read the price from the live 402 at https://2s.io/api/health/disease-surveillance, never from
a cached figure, and pay with an x402 client.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402,
or use an organization key from https://roundhouseai.io/dashboard/team.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
