Paid research · Arc
Know the price before your agent pays. Follow the job, read its evidence, and see what reached creators.
Buy with a funded Gateway wallet, or prepare a request for your own agent. Keep a private recovery file to follow your job after a disconnect.
Browse listed creator sources and their public previews to judge whether this corpus fits your question. This does not select sources for your job or guarantee a supported answer.
Research uses registered creator content and free public feed references. It does not browse the whole web or buy external marketplace endpoints. See the registry and free references.

Private recovery data is stored in this browser. Anyone using this browser profile can read it. A recovery file grants access to the job; keep it private. This is local history, not an account backup.
Exports include any saved payment acknowledgement. Importing restores access without paying again. Copied acknowledgements are seller assertions, not independent settlement proof.

Deep completion target: 300 seconds from original job acceptance.
This is a provisional target, not a guaranteed completion time. Existing package terms provide no automatic remedy. Keep the original job; do not pay again for recovery.
A recorded failure or review-required status may need attention before the target elapses. Review does not restart the original target.
Each Monthly request starts its own target when that original request is accepted, not when the plan is purchased.
Four Deep research requests over 30 days for 0.360000 USDC, compared with 0.400000 USDC separately. Each request keeps a 0.050000 USDC creator cap. The discount comes from Keryx’s service allocation.
10% off the four-request total, rounded up to equal micro-USDC allocations. Fixed, non-refundable and best effort. Failed or pending jobs use a slot; unused requests expire. No scheduled research, unlimited use or automatic renewal. Your questions use the existing public research service.
0.360000 USDC(360000 micro-USDC; decimal point, no grouping)
