Changelog

​

Platform

• A Browser task in an Atlas run is charged only when it finds what it was asked for. Tasks that find nothing, fail, time out or are cancelled are free, and a retried step never sends a task twice. See Billed Tools.
• Team skills give research agents your team’s playbooks, and connections let them call your team’s own APIs with a key they never see. Set both up in Settings → Agents, which now also holds Atlas instructions and the report format, and choose them for a run with skills and connections. Available to organizations with each feature enabled.
• On the Usage page, members see only their own runs and spend, including what their API keys spent. Team owners and organization admins see every member’s, and each member’s spend, on every plan. An API key sees the costs the person who created it may see. Wherever a member still sees a teammate’s run or search, such as a workflow’s run history or a search shared with the team, its cost shows as Hidden. See Roles & Permissions.
• Transcription is a paid source: Atlas runs pay for it from their budget, and teams can turn it off or cap it per run.

​

API & Data

• New: POST /feedback to report wrong, outdated or missed data. See Report Wrong Data.
• GET /workflows/runs and the Atlas API add spend_access, set with the reason when a cost is hidden from you.
• Errors are easier to handle and report to support. See Handling Errors.
• People Intelligence high runs take team skills and connections in every organization with the tier.
• People Intelligence Atlas runs take agent_trace and generate_report, both off by default. Generate a report any time. See Atlas integrations.
• Breaking: Regenerated clients omit unused and app-only fields from the API schema. Existing requests remain supported.
• Workflow blocks no longer need sequence_number or block_type. See Workflow definitions.
• Deprecates exclude_public_ids on search. Use exclude_entity_ids. See Search exclusions.
• Workflow runs can finish while result files are still saving. See Download results.
• Breaking: Deep search and export tasks answer only their starter and their team on GET /search/status/{task_id} and GET /job-status/{job_id}. Others get 404.
• While Sixtyfour’s data is briefly out of reach, every endpoint returns 503 with Retry-After instead of 500 or a wrong answer. See Handling Errors.
• Workflow runs still start when saving input is slow. Input that can’t be kept in time returns 503 with no charge. See Handling Errors.
• Breaking: An API key or OAuth app replays, exports or builds an exclusion list only from searches it ran, its team’s, or ones shared with its team. Others return 404. See Replay a saved search.
