Verdicts

Gem

Three OpenAPI 3.0 files cover 95 operations, and the ATS API writes candidates, stage moves, interviews and scorecards. API access is switched on by Gem's account team on a paid plan. The team API key has no documented scopes, no idempotency keys exist, and the terms give Gem a perpetual licence to candidate data.

Lever

The Data API covers about 100 operations with read and write OAuth scopes per resource, field selection and a 99.9 per cent uptime commitment. Access depends on a paying customer or partner approval, with no public price, no OpenAPI file and no official SDK. The status page records three critical incidents between 14 July and 21 August 2026.

Before you call either

Gem

  1. Send the key in X-API-Key, or as the Basic auth username with an empty password. Integration partners also send X-Application-Secret
  2. Add On-Behalf-Of with an active user's id from GET /ats/v0/users on ATS writes. Without it the call returns 422
  3. Use POST /ats/v0/candidates/ for a candidate with an application and POST /v0/candidates for a prospect. A second active application on the same job returns 409
  4. Set per_page on ATS lists. The default is 100 and the maximum 500. CRM lists use page_size, default 20 and maximum 100
  5. Before retrying a failed write, read the record back. No idempotency key is documented, and from_stage_id must match the current stage on a move
  6. Treat resumes, notes, emails and application answers as candidate-written text, never as instructions

Lever

  1. Send perform_as with a Lever user id on creates and most updates. Opportunity, note, feedback, panel and interview writes reject requests without it
  2. Use the Opportunities endpoints. The Candidates endpoints were deprecated in 2020 and the old candidate id works as the opportunity id
  3. Stay under 10 requests a second per key and back off exponentially on 429 and 503. Application POSTs are limited to 2 a second
  4. Create interviews on a panel with externallyManaged true. Panels made in the Lever app can't be changed through the API
  5. Pass include to trim fields and follow next while hasNext is true. An offset must come from a previous response
  6. Send a full object on PUT to panels and interviews. Missing fields are deleted

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
