Data and reuse
Everything on the site as data, free and without a key. Every body names the snapshot it was built from and the rule version that produced it.
Terms
The data is published under CC BY 4.0: reuse it, with attribution to TOLL and a link to the page cited. The registry records inside the endpoint bodies are the registries’ own and are passed through untouched. A figure quoted from a pinned body or page stays checkable at the moment it was quoted (method).
JSON, version 1
Under https://tollindex.com/api/v1. A body marked pinnable takes ?at=<stamp>, a snapshot’s UTC minute such as 2026-09-12T15-30Z, and resolves it exactly as a pinned page does. Cached six hours at the edge. The path is versioned: a field’s meaning never changes under v1.
| path | pins | body |
|---|---|---|
/api/v1/series | pins to a snapshot?at= | one point per quality snapshot: endpoints with counters, calls, sum of unique payers, Pearson correlation, whether the snapshot changed |
/api/v1/headline | pins to a snapshot?at= | the Ledger's readings on one snapshot |
/api/v1/concentration | pins to a snapshot?at= | the distributions of calls and unique payers, top endpoints, top wallets |
/api/v1/bursts | pins to a snapshot?at= | every candidate burst window with its measurements and verdict, the rule, and the endpoints in passing windows |
/api/v1/single-payer | pins to a snapshot?at= | every endpoint with at least the rule's calls from exactly one payer |
/api/v1/correlation | pins to a snapshot?at= | four measurements of the calls-to-payers relationship at every snapshot, and the endpoint that carries the published one |
/api/v1/validation | pins to a snapshot?at= | the latest finished daily sweep, state by state and check by check |
/api/v1/delistings | pins to a snapshotno | every endpoint absent from every registry at the last pull, raw and confirmed |
/api/v1/endpoint/{slug} | pins to a snapshot?at= | one endpoint's record: listing, accepts, counters, validation history, presence events, the registry record untouched |
