An autonomous agent that browses, fills forms, or calls tools across dozens of steps needs to look like one continuous visitor, not a new bot on every hop. Sticky residential sessions hold a single identity for the length of an agent run, so the eighth request does not get challenged like the first.
Use sticky rotating-residential sessions for AI agents and MCP-connected browsing tools. A single identity held across the full multi-step task avoids the re-authentication and CAPTCHA challenges that hit agents which change IP mid-session. Switch to ISP proxies for agents that run for hours, and datacenter only for low-stakes API-style calls to permissive endpoints.
| Expected success | 97%+ across a full multi-step agent run |
| Session hold | Up to 24h sticky for long-running agents |
| Rotation | Sticky per task; rotate only between separate tasks |
| Cost fit | ~$2.10/GB residential PAYG |

Do not use agent sessions to bypass paywalls, automate purchases without authorization, or defeat rate limits designed to protect a service from overload.
Sites correlate identity signals across a session -- cookies, IP, TLS fingerprint, timing. An agent that starts a task from one IP and finishes it from another breaks that correlation, which is exactly the pattern account-protection systems are built to flag. A sticky identity held for the full task reads as one visitor working through a normal flow.
The only reliable way to see what a real user sees is to become one.
Scheduler, proxy fetch, parser, store -- the proxy is one line in the fetch step. Everything else is pipeline you already run.
Generate a fresh sticky session ID at the start of every agent run and reuse it for every step of that run. Never share a session ID across unrelated tasks.
Once a task completes, drop the session and start the next one fresh. Reusing an identity across many unrelated tasks is what makes automated traffic detectable.
Cap sticky sessions at the length a real user session would plausibly run -- typically under an hour. A single IP active for days looks synthetic regardless of behavior.
Failed fetches are never billed, so your effective cost tracks the success rate you actually observe.
Sticky rotating-residential sessions -- one identity held for the full length of an agent run. This avoids the re-authentication and CAPTCHA challenges triggered by an IP changing mid-task.
Up to 24 hours sticky, though most agent tasks complete in minutes. Match the session length to how long a real user would plausibly take -- longer than that looks synthetic.
Yes -- the proxy is transparent to the request, so existing auth headers and cookies pass through unchanged. The sticky session just keeps the source IP consistent across calls.
Yes, as long as each agent run has its own sticky session ID. Parallel agents on separate sessions do not interfere with each other or share identity signals.
