> ## Agent Instructions
> - Base URLs: models `https://api.aisa.one/v1` (Gemini GenerateContent: `https://api.aisa.one/v1beta`); data APIs `https://api.aisa.one/apis/v1`. The `servers` of each operation in https://aisa.one/openapi.yaml is authoritative.
> - Auth: `Authorization: Bearer $AISA_API_KEY`. Never print, log, or commit the key.
> - MCP (preferred for agents): `https://mcp.aisa.one/mcp`, signed in with OAuth, so there is no key to paste.
> - Agent Skill: `npx skills add AIsa-team/agent-skills --skill aisa`. Fallback with the AIsa CLI: `aisa skills install aisa`.
> - Spending: docs, https://aisa.one/models, https://aisa.one/api, `/v1/models`, and MCP `search`, `list_categories`, `get_details`, `batch_quote`, and the `account` operation are free. Quote the exact calls before running them (MCP `batch_quote`, CLI `aisa quote --json`). If the quote reports `auto_execute_eligible: true`, run it unless the user set a tighter limit or asked only for a quote. Otherwise, tell the user in one message the planned calls, the quoted price, and a total USD budget for the task, then wait for approval. Direct HTTP calls follow the stricter rule at https://aisa.one/docs/get-started/cli.md#direct-http-fallback. Do not make paid calls to test availability. Full rule: https://aisa.one/llms.txt

# Check whether an Instagram user follows the account

> Accounts. Read only; needs social:read. Ids are yours: accounts acc_..., profiles prf_..., posts pst_...; every other object id is checked against your accounts before the call.

Resolves the follow relationship between an Instagram user and the connected account, plus their public profile counters.

`userId` is the Instagram-scoped id (IGSID) Meta gives you on a webhook: `sender.id` on `message.received`, `comment.author.id` on `comment.received`.

### When it cannot be resolved

**Meta only answers for people who have MESSAGED the account.** Commenting grants no consent, so a commenter who has never DMed you is unresolvable. That is a platform rule, not a limitation of this endpoint.

When it cannot be resolved the response is still `200` with `isFollower: null` and an `unavailableReason`, because "unknown" is a normal state to branch on:

- `consent_required`: the user has never messaged this account.
- `dm_access_disabled`: the account owner turned off Instagram Direct API access.
- `not_messageable`: the id is not a messaging-scoped id.
- `error`: a transient Graph API failure.

### Gating comment automations

To gate a comment automation on this, use the automation's `audience` rules instead of calling this per comment. They run the same lookup only on comments that actually match a keyword, and can ask the commenter to confirm with one tap.

### Caching

Answers are cached briefly per (account, user). Pass `refresh=true` right after asking someone to follow, so a follow from a moment ago is visible.

## 费用与请求规则

当前未提供请求参考价格；请使用接口支持的报价功能确认费用。 最终费用以账户适用价格及实际结算为准。

公开参考值不是你的账户报价或最终扣费。对于支持 X-AISA-Cost-Mode: quote 的接口，执行前请针对完整请求获取免费报价；执行后通过响应费用元数据和 Usage Logs 核对结算费用。1 USD 等于 1,000,000 个整数 micro-USD。
