cisco-eox-query

Python client for the Cisco End-of-Life (EOX) API.

Built on httpx for transport and pydantic for response models. This package implements the Cisco EOX API v5 as described by Cisco-End-of-Life-EOX-v5_0.wadl.

Versioning

Library major versions track the EOX API version:

The versioned implementation lives under cisco_eox_query.v5. The top-level package re-exports the latest supported version for convenience.

Install

pip install cisco-eox-query

Authentication

EOX is one of the Cisco Support APIs and requires a Smart Net Total Care (SNTC) or Partner Support Service (PSS) entitlement. Register an application at the Cisco API Console to obtain a client ID and client secret. The client exchanges them for a bearer token (client-credentials grant) and refreshes it automatically before expiry.

Usage

from cisco_eox_query import EOXClient

with EOXClient(client_id="...", client_secret="...") as client:
    records = list(client.iter_product_ids(["WS-C2960X-48TS-L", "WIC-1T="]))
    for record in records:
        print(record.eol_product_id, record.last_date_of_support)

All four WADL endpoints are exposed as search_* methods returning an EOXResponse (with records, pagination, and optional error), plus iter_* variants that follow pagination automatically:

The iter_* variants accept an optional max_pages keyword (default 1000) as a safety valve against runaway pagination; if the API never reports a final page, a PaginationError is raised instead of looping forever.

If you already hold a token:

client = EOXClient(access_token="...")

Command line

The package installs an eox-query console script. Credentials may be passed as flags or via EOX_CLIENT_ID, EOX_CLIENT_SECRET, and EOX_ACCESS_TOKEN environment variables.

eox-query --client-id ... --client-secret ... pid WS-C2960X-48TS-L WIC-1T=
eox-query --client-id ... --client-secret ... serial JAE11108ESH SAD11510738
eox-query --client-id ... --client-secret ... software 12.4\(15\)T,IOS
eox-query --client-id ... --client-secret ... dates 2011-01-01 2015-12-31 --attribs EO_SALES_DATE

Run eox-query --examples for annotated usage examples, or eox-query <command> --examples (e.g. eox-query pid --examples) for command-specific examples. Examples are also embedded in --help output.

Logs go to stderr with the format YYYY-MM-DD HH:MM:SS - SEVERITY - module - message; queried records print to stdout so they can be piped. Diagnostics are silent by default and increase with -v (info) / -vv (debug).

eox-query -vv --client-id ... --client-secret ... pid WIC-1T=

Library users get the same structured loggers (cisco_eox_query._base, cisco_eox_query.v5.client, ...) without any handler configuration.

Rate limiting and retries

The EOX API is limited to 5 requests/second and 5000 requests/day. The client handles this automatically:

• Requests are throttled to stay under the per-second limit (default 0.25s between requests, configurable via min_request_interval).
• HTTP 429/408/425/5xx responses and transport errors are retried up to max_retries times (default 3) with retry_delay seconds between attempts (default 5s), honoring the server's Retry-After header (both delay-seconds and RFC 7231 HTTP-date formats) when present.
• After retries are exhausted on a 429, a RateLimitError is raised; the CLI prints a message about hitting the daily limit and exits with code 2.
• Non-retryable errors (e.g. HTTP 403) are raised immediately.

from cisco_eox_query import EOXClient, RateLimitError

with EOXClient(client_id="...", client_secret="...", max_retries=5, retry_delay=2.0) as client:
    try:
        for record in client.iter_product_ids(["WIC-1T="]):
            print(record.eol_product_id)
    except RateLimitError as exc:
        print(f"Hit the daily request limit: {exc}")

Error handling

• EOXAPIError — raised when a response contains an EOXError payload. Call response.raise_for_error() on search_* results; the iter_* variants raise automatically.
• RetryError — a request failed after exhausting all retries.
• RateLimitError — a rate-limited request failed after exhausting retries (subclass of RetryError).
• PaginationError — pagination did not terminate within max_pages (subclass of RetryError).
• ValueError — invalid input, a malformed JSON response body, or an unexpected response shape (possible API schema change). The message includes the request path and the first validation error.

The client tolerates common API quirks: a null EOXRecord is treated as an empty result set, and a single record returned as a bare object (not wrapped in a list) is accepted.
