## Tools available

**25** tools available. First 12:

- `COUNTDOWN_API_CLEAR_ALL_REQUESTS` — Clear Collection Requests — Clears (removes) all pending requests from a collection. Use this to reset a collection before adding new requests, or to cancel all queued requests. The collection must be in 'idle' status. Returns the updated collection details after clearing.
- `COUNTDOWN_API_COLLECTIONS_CREATE_COLLECTION` — Create a new collection — Tool to create a new collection. Use when you need to batch and orchestrate multiple requests on a schedule.
- `COUNTDOWN_API_COLLECTIONS_GET_COLLECTION` — Get Collection — Tool to retrieve details for a single collection by ID. Use when you need collection metadata and counts for a given collection ID.
- `COUNTDOWN_API_COLLECTIONS_LIST_COLLECTIONS` — List Collections — Tool to list all collections for the authenticated account. Use when you need to retrieve paginated collections with filtering, sorting, and timing constraints.
- `COUNTDOWN_API_COLLECTIONS_START_COLLECTION` — Start Collection — Start processing a collection's queued requests on the Countdown API. Use this tool to manually trigger a collection to begin executing its requests. The collection must have at least one request added to it before it can be started. You need sufficient API credits to run all requests in the collection. Prerequisites: - Collection must exist (use List Collections or Create Collection first) - Collection must have at least one request added - Sufficient API credits available for the number of requests - Collection must not already be running
- `COUNTDOWN_API_COLLECTIONS_UPDATE_COLLECTION` — Update an existing collection — Update an existing collection's settings. Use this to modify collection properties like name, schedule, priority, notification settings, or enabled status. The collection_id must be obtained from list_collections or create_collection. Only specified fields are updated; omitted fields retain their current values.
- `COUNTDOWN_API_CORE_API_SEND_REQUEST` — eBay Autocomplete — Tool to fetch eBay autocomplete suggestions. Use when needing search-term-based suggestions from Countdown API.
- `COUNTDOWN_API_CREATE_COLLECTION_REQUEST` — Create Collection Request — Tool to create new requests within a collection for bulk eBay data retrieval. Use when you need to add search, product, reviews, or other eBay data queries to a collection that will be executed on schedule. Collections must be in 'idle' status to accept new requests.
- `COUNTDOWN_API_CREATE_DESTINATION` — Create Destination — Creates a cloud storage destination where batch result sets will be automatically uploaded. Supports Amazon S3, S3-compatible services (MinIO, DigitalOcean Spaces), Google Cloud Storage, Microsoft Azure Blob Storage, and Alibaba Cloud OSS. When enabled=true, the API validates credentials by uploading and deleting a test file. Set enabled=false to create the destination without credential validation.
- `COUNTDOWN_API_DELETE_COLLECTION` — Delete Collection — Tool to delete a collection and its configuration by ID. Use when you need to remove an existing, non-running collection.
- `COUNTDOWN_API_DELETE_DESTINATION` — Delete Destination — Tool to delete a destination by ID. Use when you need to remove an existing destination.
- `COUNTDOWN_API_DELETE_SINGLE_REQUEST` — Delete Single Request — Delete a specific request from a Countdown API collection by its ID. Use this to remove individual requests that are no longer needed. The collection must not be running when deleting requests.

## How agents use Countdown API

Inside a Definable workflow, Countdown API is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → Countdown API** — the Researcher (GPT-5.5) pulls context from Countdown API (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → Countdown API** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into Countdown API (create record, post message, draft email).
- **Designer / Engineer → Distributor → Countdown API** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via Countdown API (attach file, open PR comment, post status).

The Verifier checks every Countdown API call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
