Client API Reliability Retainer Build (10-15 days)
A productized engagement that inventories a client's live integrations, hardens the endpoints their revenue depends on, and converts the result into a monthly governance retainer. Built for agencies whose delivery work already touches client CRMs, payment rails, or LLM features. Time: 10-15 days.

Client API Reliability Retainer Build (10-15 days)
A productized engagement that inventories a client's live integrations, hardens the endpoints their revenue depends on, and converts the result into a monthly governance retainer. Built for agencies whose delivery work already touches client CRMs, payment rails, or LLM features.
- A signed statement of work that grants read access to the client's API inventory, gateway configs, and error logs A named client-side technical owner who can approve rate limits, auth changes, and deployment windows An inventory of every third-party service the client pays for, including LLM providers and any IoT or device fleets A documented escalation path for production incidents, with on-call contacts on both sides Agreed severity tiers so the retainer's response times are contractual, not improvised
- 1.Map every inbound and outbound integration the client runs, including internal-only endpoints
- 2.Log owner, auth method, and last-known traffic volume per endpoint
- 3.Flag endpoints with no documented owner as immediate risk items
- 1.Pull 30 days of error logs and latency data from the chosen platform or gateway
- 2.Rank endpoints by failure frequency and business criticality
- 3.Identify which failures reached the client's customers versus staying internal
- 1.Review authentication and key rotation practices across the integration estate
- 2.Check whether agent or LLM traffic shares credentials with human-facing systems
- 3.Document any secrets stored in code, spreadsheets, or shared notes
- 1.Audit rate limits and spend caps on outbound model calls and paid third-party APIs
- 2.Compare current caps against observed peak usage
- 3.Draft recommended thresholds with headroom for client growth
- 1.Assess documentation coverage for the endpoints the client's own team consumes
- 2.Identify specs that have drifted from live behavior
- 3.Note where an interactive reference would cut support tickets
- 1.Present the risk register to the client's technical owner
- 2.Agree which fixes ship this engagement and which move to the retainer
- 3.Confirm the deployment window and rollback plan
- 1.Implement auth hardening and key rotation on the highest-risk endpoints
- 2.Apply agreed rate limits and spend caps in the gateway layer
- 3.Add alerting on the three failure modes most likely to recur
- 1.Publish or refresh the endpoint reference for the client's internal consumers
- 2.Include authentication steps and a working example request per endpoint
- 3.Hand the draft to the client's team for a 48-hour review
- 1.Run a load test against peak-traffic endpoints at 2x observed volume
- 2.Record latency and error rates at each step
- 3.Fix any endpoint that degrades before the client sees the numbers
- 1.Write the incident runbook covering the top five failure scenarios
- 2.Assign a first responder and a client-side escalation contact per scenario
- 3.Test the runbook with one simulated failure
- 1.Compile the governance pack: inventory, risk register, thresholds, runbook
- 2.Set the retainer's monthly cadence for reviews and rotation
- 3.Present the pack and the retainer terms to the client's decision-maker
The setup fee covers roughly 40 to 60 hours of senior integration work, which most agencies already absorb informally when a client's endpoints break mid-campaign. Packaging that work as a fixed-scope engagement converts unbilled firefighting into a paid line item, and the retainer attaches recurring revenue to infrastructure the client cannot easily hand to another vendor. Margin holds because the monthly cadence is monitoring and rotation, not net-new build.
- Integration inventory with owner, auth method, and traffic volume per endpoint
- Risk register ranking endpoints by failure frequency and business criticality
- Gateway configuration pack covering auth, rate limits, and spend caps
- Incident runbook with named responders and a tested failure simulation
- Monthly governance retainer scope with review cadence and rotation schedule
The client's technical owner signs off on the risk register and runbook, and every endpoint flagged as high risk has a deployed fix or a scheduled retainer task with a named owner.
