Use the data · API v1

Public data, without a gate.

The current Moat Index snapshot is available without an account, API key, or paid tier. The public endpoints are read-only and return prebuilt static files—never a live database or score-engine query.

Files are updated nightly after scoring completes, with the point-in-time date inside every file. This is not a realtime API; polling more often will not produce fresher data.

Full open-data catalog

The open-data portal presents the datasets named by the current publication catalog. Entries with a verified manifest supply CSV and JSON downloads, a source-event-labeled vintage, schema, citation and SHA-256 values. Manifest outages and conditional third-party datasets remain explicit without inferred downloads.

Dates and nulls

Every CSV row carries snapshot_as_of, captured_at, and as_of_fiscal_year; JSON carries top-level asOfplus each record’s capture and fiscal-year dates. A blank CSV field or JSON null means the source value is honestly null; it does not mean zero. Both responses also send the snapshot date in X-Data-As-Of. Scores can reflect different fiscal years because companies file on different schedules.

Fields

The legacy Top-100 CSV preserves its v1 column shape, but licensed market-capitalization, verdict, price, discount and per-share valuation fields are blank or null. The v2 catalog uses the per-dataset schemas shown on the data portal.

Rate expectations and availability

Responses are cached at the edge for one hour, and the underlying content-addressed artifacts carry immutable cache directives. There is no uptime SLA. Reuse a downloaded snapshot instead of polling: one request per hour is the expected maximum for routine automation. An origin safety limit of600 requests per minute per forwarded client address applies on cache misses; ordinary edge-cache hits do not consume it. On 429 or 503, back off and retry later; a 503 is returned rather than publishing an empty or unverifiable snapshot.

Versioning

The Top-100 endpoint remains API v1. Open-data catalogs and manifests carry machine-readable schema versions. Versioned vintage paths are published with immutable cache directives; incompatible schemas publish a new version.
