note: Captured from the EDI Developer portal endpoint documentation, the API FAQ,
  and live probes; EDI publishes no OpenAPI or cross-cutting conventions page, so
  only documented/observed behavior is recorded.
authentication:
  style: api-key
  header: Authorization
  reference: authentication/exchange-data-international-authentication.yml
api_style:
  paradigm: rpc-over-http
  detail: Each of the 24 API products exposes verb-named GET endpoints on the shared
    https://api3.exchange-data.com base (GetLatestEODPrices, GetLatestCorporateActions,
    GetBondSecurityMaster, ...), with query-string parameters for identifiers (MIC,
    LocalCode, ISIN, FIGI) and format.
formats:
  request: query-string parameters
  response:
  - json
  - psv
  parameter: Format
  detail: The Format query parameter selects the response encoding (for example json
    or PSV pipe-separated values); the Developers and Startups page also advertises
    JSON, XML and CSV output options.
pagination:
  style: token
  response_fields:
  - pageCount
  - totalCount
  - next
  detail: Responses include pageCount (records returned, example 10000), totalCount,
    and a next token; the caller passes the opaque next token back to fetch the next
    chunk of records.
identifiers:
  detail: Queries key on ISO 10383 MIC, exchange-local codes/tickers, ISO 6166 ISIN,
    US CUSIP-derived uscode, FIGI, and the EDI-assigned secid linkage code; currencies
    use ISO 4217.
idempotency:
  supported: null
  detail: No idempotency-key mechanism is documented; the public surface is read-only
    GET data retrieval.
versioning:
  scheme: none-documented
  detail: No version segment or versioning policy is published; the host name (api3)
    carries the platform generation.
rate_limits:
  documented: false
  detail: No rate-limit headers or quotas are documented. The API FAQ notes the platform
    runs on GCP and is sized to absorb usage spikes; the Playground UI shows 20 records
    and allows downloading up to 1,000 records per request.
error_envelope:
  shape: '{"error": "<message>"}'
  reference: errors/exchange-data-international-problem-types.yml
data_freshness:
  detail: Per the API FAQ, API data increments in batches (for example WCA increment 0
    between 5am-7am GMT); clients poll for completed sets, and there is no push/status
    alert mechanism on the API (SFTP delivery is the push alternative).
