Posts createCreate 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
Posts cross postPost 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 get usageUsage 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.
