Access needs LinkedIn's approval and a member's OAuth consent, standard rate limits are not published, and no OpenAPI specification was found.\n\n**X Ads API.** Rate limits are published per endpoint type, a sandbox host never serves ads, and the X Ads MCP server has separate read and write scopes and creates campaigns paused. The REST API needs OAuth 1.0a signing and an approved app, no OpenAPI file covers it, and the official Python and Ruby SDKs were last released in May 2022.\n\n## Before you call either\n\n### LinkedIn Marketing APIs\n\n1. Send `Linkedin-Version: YYYYMM` and `X-Restli-Protocol-Version: 2.0.0` on every call. A missing or sunset version returns an error (426 for a deprecated one)\n2. Create one test ad account with `\"test\": true` and build there first. Its creatives are auto-rejected and never billed, and it returns no reporting data\n3. Create campaigns as DRAFT or PAUSED and check `servingStatuses` before activating. Some validation is postponed until activation\n4. Pass `fields=` on adAnalytics. Responses stop at 15,000 elements and the endpoint throttles at 45 million metric values per 5 minutes\n5. On Development tier, map each ad account to the app in the Developer Portal. Edits are limited to five accounts\n\n### X Ads API\n\n1. Build against `https://ads-api-sandbox.x.com/12/` first. Create a test account with `POST accounts` and a funding instrument there before touching a live account\n2. On HTTP 429 wait until the time in `x-rate-limit-reset`. On 503 wait for `retry-after`. The docs say apps that ignore these can be throttled or lose access without notice\n3. Read the account-level limit from `x-account-rate-limit-*` when present and use `x-rate-limit-*` only when it is absent\n4. For a read-only MCP session request `ads.read offline.access` only. Without `offline.access` the token expires in about two hours with no refresh\n5. Page with `count` (1 to 1,000, default 200) and `cursor` until `next_cursor` is null. Analytics endpoints page by time range instead, and `with_total_count` cannot be combined with `cursor`\n\n## Questions\n\n### Which is better for AI agents, LinkedIn Marketing APIs or X Ads API?\n\nLinkedIn Marketing APIs scores 62.4 (B) on agent readiness against X Ads API's 57.3 (C), and leads in 6 of 7 scored categories.
