locus.report
EPA National Emissions Inventory facility and pollutant rows near an address. Perfect for: environmental diligence, facility emissions research, per-pollutant tonnage, and distance-ranked industrial context. Summary is bounded; detailLevel=full returns the large facility-pollutant matrix. Periodic inventory estimates only, not monitoring, ambient concentration, exposure, health evidence, or a burden score. Charge-free when no facility rows resolve.

Reported by the source catalog.
Paid to
0xF121fbeceC43e1B616D47285851c20d5fC64431bThe wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.

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.
Live 402 challenge
Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

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
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 30 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.
Show the promptHide the prompt
Using Roundhouse, look up the x402 service locus.report 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=locus.report' 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://locus.report/api/locus-nei-emissions-nearby, 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.
