Get daily aggregated metrics Args: platform: Filter by platform (e.g. "instagram", "tiktok"). Omit for all platforms. profile_id: Filter by profile ID. Omit for all profiles. account_id: Filter by account ID from_date: Inclusive start date (ISO 8601). Defaults to 180 days ago. to_date: Inclusive end date (ISO 8601). Defaults to now. source: Filter by post origin. "late" for posts published via Zernio, "external" for posts imported from platforms. attribution: How each post's engagement is attributed to a day. "publish" (default) sums each post's lifetime total on its publish date. "received" buckets the per-day increase in engagement by the day it actually arrived (engagement-over-time), so engagement on older posts appears on the day it was gained rather than the post's publish date.

Get post analytics timeline Args: post_id: The post to fetch timeline for. Accepts an ExternalPost ID, a platformPostId, or a Zernio Post ID. (required) from_date: Start of date range (ISO 8601). Defaults to 90 days ago. to_date: End of date range (ISO 8601). Defaults to now.

Bulk upload from CSV Args: dry_run

Create a social media post. Can be saved as DRAFT, SCHEDULED, or PUBLISHED immediately. ⚠️ IMPORTANT - Choose the correct mode based on user intent: **DRAFT MODE (is_draft=True)** Use when user says: "draft", "borrador", "save for later", "don't publish", "save it", "guardar" → Post is saved but NOT published and NOT scheduled. User can edit it later. **IMMEDIATE MODE (publish_now=True)** Use when user says: "publish now", "post now", "publica ya", "immediately", "right now", "ahora" → Post goes live IMMEDIATELY. **SCHEDULED MODE (default)** Use when user says: "schedule", "programar", "in X minutes/hours", "at 3pm", "tomorrow" → Post is scheduled for future publication. Use schedule_minutes to set the delay. ⚠️ MULTI-ACCOUNT USERS (agencies, multi-client setups): If the user has more than one account on the target platform, you MUST pass `account_id`. Call `accounts_list` (or `profiles_list` then `accounts_list`) first to discover the right ID. If you omit account_id when multiple accounts exist, the tool returns an error listing the candidates - use it to retry. Examples: - "Create a draft tweet" → is_draft=True - "Post this to Twitter now" → publish_now=True - "Schedule a LinkedIn post for 2 hours from now" → schedule_minutes=120 - "Post this to Acme's Twitter" → call accounts_list, find Acme's twitter ID, pass account_id

Post the same content to multiple platforms at once. ⚠️ IMPORTANT - Choose the correct mode based on user intent: **DRAFT MODE (is_draft=True)** Use when user says: "draft", "borrador", "save for later", "don't publish" → Posts are saved but NOT published. User can edit them later. **IMMEDIATE MODE (publish_now=True)** Use when user says: "publish now", "post now", "immediately" → Posts go live IMMEDIATELY on all platforms. **SCHEDULED MODE (default)** Use when user says: "schedule", "programar", "in X hours" → Posts are scheduled for 1 hour from now. ⚠️ MULTI-ACCOUNT USERS: - To pick a specific account per platform, pass `account_ids` parallel to `platforms` (same order, comma-separated). Use empty string for a position to fall back to profile/auto-resolution. - To target multiple accounts of the SAME platform in one call, repeat the platform: platforms='twitter,twitter', account_ids='acc_a,acc_b'. - If you omit account_ids and the user has multiple accounts for any of the requested platforms, the tool errors with the candidate list - use it to retry.

Usage snapshot (default) or billed-spend metering (with params) Args: reconcile: Snapshot mode only. For Stripe subscription users, `true` forces a subscription reconciliation pass even when cached plan data looks complete. range: Window to report. `cycle` / `prev-cycle` resolve to the customer's real billing-period bounds (falling back to a trailing 30 days when no invoice exists yet); `7d`…`12mo` are trailing windows; `custom` uses `from` / `to`. from_: Inclusive start (UTC date). Required when `range=custom`. to: Inclusive end (UTC date). Required when `range=custom`. Max span 366 days. granularity: Bucketing of the `days` series: `day` (one row per UTC day), `month` (one row per calendar month, dated to the 1st), or `total` (no series, read `totals`). Does not affect `totals`. group_by: Metering mode. Adds `attribution`: the window's spend split per profile or per account (keys are ids; resolve names via `GET /v1/profiles` / `GET /v1/accounts`). profile_id: Metering mode (pair with `range`). Project the payload onto this profile's attributed share. Mutually exclusive with `accountId`, and `groupBy` (if given) must be `profile`; 404 when the profile is not in your team (or outside a scoped key's profiles). account_id: Metering mode (pair with `range`). Project the payload onto this account's attributed share. Mutually exclusive with `profileId`, and `groupBy` (if given) must be `account`; 404 when the account is not visible to the caller.
