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 # Link or unlink asset group assets > Ad Campaigns. Changes the ad account without starting or raising spend; audited. validateOnly=true checks the request without acting and needs no confirmation. Links new or existing assets to a Performance Max asset group and unlinks others in one change, keeping unlinked assets in the account library. Link existing assets or new content to the asset group, and unlink assets, in one atomic request. Links are applied before unlinks, so swapping the last asset of a role does not trip Google's per-role minimum. A request reference price is not currently available; use a request quote where supported. Account-specific pricing and final settlement may differ. ## Request contract * **Method and path:** POST /apis/v1/ads/campaigns/\{campaignId}/asset-groups/\{assetGroupId}/assets * **Availability:** enabled * **Request URL template:** `https://api.aisa.one/apis/v1/ads/campaigns/{campaignId}/asset-groups/{assetGroupId}/assets` * **campaignId:** path; required * **assetGroupId:** path; required * **connectionId:** query; required * **Runtime facts:** fe60122939c67dc98a3a6ac6b97bd5c326b526105150c8959304dd2160d4dd09 [Complete OpenAPI definition](https://aisa.one/docs/reference-contracts/aisa-ads.json) Effective request and pricing declaration (including authentication and referenced schemas): ```json theme={null} { "operationId": "post_aisa_ads_apis_v1_ads_campaigns_campaignid_as_2291fd", "method": "POST", "path": "/apis/v1/ads/campaigns/{campaignId}/asset-groups/{assetGroupId}/assets", "servers": [ { "url": "https://api.aisa.one" } ], "parameters": [ { "description": "Google Ads campaign id.", "in": "path", "name": "campaignId", "required": true, "schema": { "pattern": "^\\d+$", "type": "string" } }, { "description": "Google asset group id.", "in": "path", "name": "assetGroupId", "required": true, "schema": { "pattern": "^\\d+$", "type": "string" } }, { "description": "The ads connection (adc_...) the request runs on: one of yours, from GET /apis/v1/ads/connections.

Account-specific pricing and final settlement may differ. Published reference values are not an account-specific quote or a settled charge. For endpoints supporting X-AISA-Cost-Mode: quote, obtain a free quote for your exact request before execution; reconcile the settled cost with response metadata and Usage Logs. USD amounts use 1,000,000 integer micro-USD per dollar. ## OpenAPI ````yaml reference-contracts/aisa-ads.json POST /apis/v1/ads/campaigns/{campaignId}/asset-groups/{assetGroupId}/assets openapi: 3.1.0 info: description: '' title: AIsa Ads version: '1' x-aisa-capabilities: idempotency: Idempotency-Key max_price: X-AISA-Max-Price-USD quote: header: X-AISA-Cost-Mode value: quote x-aisa-configured-paths: [] x-aisa-document: facts_hash: fe60122939c67dc98a3a6ac6b97bd5c326b526105150c8959304dd2160d4dd09 generator_version: '3' protocol_version: '1' schema_version: '1' composer_version: '27' response_pending: [] document_hash: sha256:ba353f59e89e1ebabe0e301d8ef57d3cbfa6bb406a8c591ee9c3833d64b60520 x-aisa-plans: builder: 1 display_plan: payg payg: 1 similarweb_payg: 1 team: 1 version: e70a0959cd1b93b84ae16dffd7a538273ddb9c1d46277b82823c37ff1b6bc0fb x-aisa-provider: aisa-ads x-aisa-catalogs: aisa-ads: title: AIsa Ads description: '' x-aisa-document: facts_hash: fe60122939c67dc98a3a6ac6b97bd5c326b526105150c8959304dd2160d4dd09 generator_version: '3' protocol_version: '1' schema_version: '1' x-aisa-plans: builder: 1 display_plan: payg payg: 1 similarweb_payg: 1 team: 1 version: e70a0959cd1b93b84ae16dffd7a538273ddb9c1d46277b82823c37ff1b6bc0fb x-aisa-capabilities: idempotency: Idempotency-Key max_price: X-AISA-Max-Price-USD quote: header: X-AISA-Cost-Mode value: quote servers: - url: https://api.aisa.one security: - bearerAuth: [] paths: /apis/v1/ads/campaigns/{campaignId}/asset-groups/{assetGroupId}/assets: post: summary: Link or unlink asset group assets description: >- Ad Campaigns.
