Sherlock Calls
for Twilio + VAPI + Datadog
VAPI runs your AI agents. Twilio carries the calls. Datadog monitors your infrastructure. When something goes wrong, the root cause could be in any of the three. Sherlock Calls connects all of them — so you can find it in seconds, not hours.
TL;DR — What beta users get access to
- 1
Sherlock Calls connects to Twilio, VAPI, and Datadog simultaneously with read-only API access, enabling full-stack reliability investigation of your AI calling infrastructure from a single Slack question.
- 2
Ask questions that span all three platforms: did a Datadog infrastructure event cause VAPI agent failures that showed up as Twilio call errors, which VAPI agents have the worst Twilio error rates during Datadog alert windows, and how your AI call stack SLA looks across all three layers.
- 3
Sherlock correlates infrastructure events, agent sessions, and telephony call records, returning a root-cause timeline in under 5 seconds.

The Investigation Gap
What's invisible when you use Twilio + VAPI + Datadog without Sherlock
Each platform shows you its own data. But the questions that matter most live in the gaps between them.
Call failures could be Twilio, VAPI, or infra — and you can't tell which
When AI call success rates drop, the root cause could be a Twilio carrier issue, a VAPI agent error, or an infrastructure event captured in Datadog. Without correlating all three, your on-call team is guessing — and guessing costs hours.
Infrastructure deploys that break AI calls are discovered too late
A deployment event in Datadog may cause VAPI agent errors that surface as Twilio call failures — but these three events are logged in three separate systems. By the time your team correlates them manually, the incident has been ongoing for an hour.
AI call stack SLA calculations span three systems
Your AI call stack uptime depends on Twilio availability, VAPI reliability, and infrastructure health. Calculating a true end-to-end SLA — and communicating it to customers — requires correlating all three, which nobody does without tooling.
Cross-Provider Questions
What teams ask Sherlock about Twilio + VAPI + Datadog
Questions that would take hours to answer manually — answered in under 5 seconds from Slack.
- SC“Did any Datadog infrastructure events precede the VAPI agent failures that caused Twilio call errors yesterday?”
- SC“Which VAPI agents have the highest Twilio error rate during Datadog alert windows?”
- SC“Give me a timeline of Datadog events, VAPI failures, and Twilio errors for the last 24 hours”
- SC“What's the end-to-end AI call success rate across Twilio and VAPI during periods of high Datadog alert volume?”
- SC“Show me all VAPI agent sessions that failed during the last Datadog deployment event, and how they appeared in Twilio”

FAQ
Common questions about Sherlock + Twilio + VAPI + Datadog
How does Sherlock correlate Twilio, VAPI, and Datadog events?
- Sherlock queries all three APIs simultaneously and aligns events by timestamp, correlating Twilio call error windows with VAPI agent failure periods and Datadog infrastructure events. It surfaces temporal correlations automatically and presents them as a unified timeline.
Can Sherlock help us write post-mortems for AI call incidents?
- Yes. Sherlock can reconstruct the full event sequence across Twilio, VAPI, and Datadog for any incident window — giving your team the raw material for a complete post-mortem in seconds rather than hours.
Does this work if VAPI and Datadog aren't natively integrated?
- Yes. Sherlock queries all three APIs independently and performs the correlation itself. No native integration between any of the three platforms is required.
Can Sherlock calculate our end-to-end AI call SLA across all three platforms?
- Yes. Sherlock can compute AI call success rates, availability windows, and error rates across Twilio, VAPI, and Datadog for any time period — giving you the inputs for a true end-to-end SLA calculation.
Is the Twilio + VAPI + Datadog combination in beta?
- Yes — this combination is currently in invite-only beta. Apply for early access and we'll reach out if your stack is a good fit.
