Access is by support ticket or a paid partner contract, and the API Fair Use Policy bars connecting third-party AI or LLM tools or MCP without Bullhorn's written permission. No OpenAPI file or numeric rate limit was found.\n\n**Greenhouse.** Harvest v3 pairs per-endpoint OAuth scopes with Markdown docs that embed an OpenAPI 3.1 definition for each call, and the beta MCP server blocks every DELETE. Access needs a paying customer account, with no public price, trial or self-serve sandbox, and no numeric rate limit or idempotency key was found in the reviewed documentation.\n\n## Before you call either\n\n### Bullhorn\n\n1. Confirm the customer holds Bullhorn's written permission for AI or LLM access before any call. The API Fair Use Policy forbids it otherwise\n2. Call `/rest-services/loginInfo?username=` first to learn the data centre, then use the returned OAuth and REST URLs and follow any 307 redirect\n3. Log in once and reuse `BhRestToken` until a call returns 401, then use the refresh token. Bullhorn limits login rates and may block frequent logins\n4. Send `BhRestToken` as a header, never in the URL, and always pass `fields`. `fields=*` is blocked outside `/meta`\n5. On 429 wait one second and retry. Writes have no idempotency key, so read the record back before repeating a PUT\n\n### Greenhouse\n\n1. Request a token from https://auth.greenhouse.io/token with client credentials, then send it as a Bearer token to https://harvest.greenhouse.io/v3. Tokens expire, so repeat on 401\n2. Put filters and `per_page` on the first list request only. A `cursor` must be the only query parameter, or the call returns 422\n3. Send the current stage as `from_stage_id` when moving an application. It guards against stale moves. Other writes have no idempotency key, so check before retrying\n4. Read `X-RateLimit-Remaining` on every response and wait for `Retry-After` on 429. The window is 30 seconds\n5. Expect empty list results or 403 unless the token's user is a Site Admin with the needed permissions\n\n## Questions\n\n### Which is better for AI agents, Bullhorn or Greenhouse?\n\nGreenhouse scores 64.8 (B) on agent readiness against Bullhorn's 46.7 (D), and leads in 5 of 7 scored categories.
