# As-of dataset manifests (any key)

`GET /manifests`

## Request

- Base URL: `https://madeonsol.com/api/v1`
- URL: `https://madeonsol.com/api/v1/manifests`
- Auth: HTTP bearer

One manifest per dataset per night (measured on the streaming replica at `data_as_of`): rows written in the previous 24 h, min/max event timestamp, planner row estimate, a `schema_hash` (md5 of the column:type list — a change means the shape of the data changed) and a `fingerprint` (md5 of dataset|max_ts|rows_24h|estimate). Cite the fingerprint in a report and it names the exact dataset state the numbers came from. Default = latest per dataset; `?dataset=` walks one dataset's history.

## Query parameters

- `dataset` string
- `limit` integer

## Response `200`

OK. `{ manifests[], count, dataset, note }` — each: `dataset`, `data_as_of`, `produced_at`, `producer`, `ts_column`, `rows_24h`, `min_ts`, `max_ts`, `row_count_estimate`, `schema_hash`, `fingerprint`.

- object
  - `manifests` object[]
    - `dataset` string
    - `data_as_of` string, date-time: Night the manifest was measured on the streaming replica
    - `produced_at` string, date-time
    - `producer` string
    - `ts_column` string
    - `rows_24h` integer
    - `min_ts` string, nullable
    - `max_ts` string, nullable
    - `row_count_estimate` integer: Planner estimate (partitions summed), not an exact count
    - `schema_hash` string: md5 of the column:type list
    - `fingerprint` string: md5(dataset|max_ts|rows_24h|estimate)
  - `count` integer
  - `dataset` string, nullable
  - `methodology_version` string
  - `note` string

## Other responses

- `401`: Missing or invalid API key, or an expired free-tier key. Authentication-stage error: no `X-RateLimit-*` headers, no `_rid`.
- `403`: Forbidden. One of: the key's tier is below this endpoint's or parameter's gate (`tier_required` with an `upgrade` block); the public demo key used outside its allow-list (`demo_key_endpoint_not_allowed`); an invalid or revoked key; an origin-restricted key called from a disallowed origin (`code` `origin_not_allowed` / `origin_required`). `X-RateLimit-*` headers are present only on `tier_required`.
- `429`: Too many requests. Every 429 carries `Retry-After`. A quota 429 (`rate_limit_exceeded`, with `X-RateLimit-*`), a heavy-query concurrency 429 (`error_kind` `concurrency`/`capacity`), or the per-IP authentication-failure block (30 failed auths/min; plain `error` + `retry_after_seconds`, no `X-RateLimit-*`).
- `500`: Unexpected server error from the route (`Internal server error`, with `_rid`). Safe to retry with backoff. A failed API-key lookup is a 503 `auth_backend_unavailable`, never a 500.
- `503`: The API-key or subscription lookup could not be answered (authentication stage). Retryable and not your fault: it is never counted as a failed authentication. Honour `Retry-After`; no `X-RateLimit-*`, no `_rid`.
