# Read the page now, on demand

`POST /corroborations/{id}/verify`

## Request

- Base URL: `https://api.epovest.com/v1`
- URL: `https://api.epovest.com/v1/corroborations/{id}/verify`
- Auth: HTTP bearer

One pass refreshes the two findings of the line, dated, and every line carries the latest
result as `page_check`. On the MENTION: the passage around the brand is archived on the line,
and when a change has been found, `excerpt_before` carries the passage as it stood before
`changed_at`. On the LINK: every link of the page towards an address of the brand, each with
its rel tokens, its anchor text and its target. Free of charge. Manager or above.

## Response `200`

The corroboration, with the findings of the pass.

- CorroborationEnvelope
  - `corroboration` Corroboration, required
    - `id` string, uuid, required
    - `project_id` string, uuid, required
    - `url` string, required: The exact page.
    - `domain` string, required: The registrable domain the page sits on, derived from the address by the same normalizer as the Atlas. Correcting the `url` always recomputes it.
    - `label` string, nullable, required
    - `notes` string, nullable, required
    - `published_on` string, date, nullable, required: The day the page was PUBLISHED, distinct from `created_at`, the day it was recorded. It is the publication date that means something against the citation curves.
    - `author` string, nullable, required
    - `request_channel` 'available' | 'none' | 'unknown', required: Whether someone can be asked to change the page: `available` (a contact or a process exists), `none` (nobody to ask) or `unknown` (not filled in, the default). Three states, because "no channel" and "not filled in" are two different facts.
    - `monitoring` 'off' | 'daily' | 'weekly' | 'monthly', required: The cadence of the automatic watching of a corroboration. Each executed check runs the same pass as the on-demand check and debits the prepaid balance per executed check.
    - `monitoring_paused` boolean, required: True while the passes wait on the balance, the cadence kept: a top-up resumes them as they were.
    - `archived` boolean, required
    - `page_check` PageCheck, required: The latest reading of the page, refreshed by `POST /corroborations/{id}/verify` and by the watching cadence.
      - `readability` 'pending' | 'html' | 'unreadable' | 'blocked' | 'unreachable' | 'no_page', required
      - `checked_at` string, date-time, nullable, required
      - `http_status` integer, nullable, required
      - `mention` object, required: The finding on the passage around the brand: `unchanged`, `changed` (the passage moved, worth re-reading), `figures` (it moved on NUMBERS only, such as a rank or a counter, so `changed_at` stays where it was) or `gone` (the page did not answer).
        - `finding` 'unchanged' | 'changed' | 'figures' | 'gone' | 'null', nullable
        - `excerpt` string, nullable
        - `excerpt_before` string, nullable: The passage as it stood BEFORE `changed_at`, so comparing the two texts says what moved without reading the whole page again.
        - `extractor` string, nullable
        - `changed_at` string, date-time, nullable
      - `link` object, nullable, required: The finding on the links of the page towards the addresses of the brand.
        - `finding` 'unchanged' | 'changed' | 'gone' | 'none'
        - `changes` unknown[]
          - unknown
        - `outbound` integer, nullable
        - `noindex` boolean, nullable
        - `page_nofollow` boolean, nullable
        - `canonical_elsewhere` string, nullable
        - `links` LinkSighting[]
          - `url` string
          - `kind` string, nullable
          - `anchor` string, nullable
          - `rel` string[]: The rel tokens of the link, among `nofollow`, `sponsored` and `ugc`.
          - `html_target` string, nullable
          - `title` string, nullable
          - `in_main_content` boolean, nullable
          - `nature` string, nullable
          - `final_url` string, nullable
          - `hops` integer, nullable
          - `final_status` integer, nullable
          - `first_seen` string, date-time
          - `last_seen` string, date-time
          - `changed_at` string, date-time, nullable
    - `created_at` string, date-time, required

## Other responses

- `401`: `unauthenticated`: missing, unknown or revoked key.
- `403`: `insufficient_scope`: the credential may not do this, either because the key lacks the scope, or, on a one-click connection, because the person lacks the role the action needs (manager, or owner to start, pause and top up). On that path, read it as "this person may not do this" and tell them which role the action needs.
- `404`: `not_found`: unknown for this account.
- `409`: `corroboration_archived`: put the line back live with `POST /corroborations/{id}/archive` and `{"archived": false}` to check it again.
- `429`: `rate_limited`: 120 requests per minute per credential, sliding window. Retry after `Retry-After` seconds.
