Sherlock Calls
for Twilio + Retell AI
Retell AI handles your conversations. Twilio handles your calls. Sherlock Calls connects both — so you can ask why calls fail, which agents perform best, and what everything costs, from a single Slack message.
TL;DR — What beta users get access to
- 1
Sherlock Calls connects to both Twilio and Retell AI with read-only API access, letting you investigate your combined stack without switching dashboards or writing any code.
- 2
Ask cross-provider questions neither platform can answer alone: which Retell AI agents produce the most Twilio errors, what the combined cost per successful conversation is, and where conversations drop off.
- 3
Sherlock correlates Twilio call records with Retell AI conversation logs and returns a single sourced answer in under 5 seconds.

The Investigation Gap
What's invisible when you use Twilio + Retell AI without Sherlock
Each platform shows you its own data. But the questions that matter most live in the gaps between them.
Conversation drop-offs don't have a single source of truth
When a Retell AI conversation ends abruptly, was it a Twilio connection issue or a Retell AI agent logic failure? Both platforms log the event differently, and without a unified view, your team spends hours reconstructing what happened.
Agent performance is invisible across the telephony boundary
Retell AI shows you conversation metrics. Twilio shows you call quality. But which Retell AI agent configurations produce the cleanest Twilio call records — lowest error rates, shortest drop durations — is data that doesn't exist in either platform alone.
Cost per completed conversation is a mystery
Twilio invoices you for telephony. Retell AI invoices you for agent compute. The actual cost per successfully completed AI conversation spans both bills, and without correlating them, you can't know whether your AI calling is profitable.

FAQ
Common questions about Sherlock + Twilio + Retell AI
How does Sherlock correlate Twilio calls with Retell AI conversations?
- Sherlock uses timestamp and phone number matching to correlate Twilio call records with Retell AI conversation logs. It queries both APIs in parallel when you ask a question and joins the results automatically.
Can Sherlock tell me why a specific Retell AI conversation failed in Twilio?
- Yes. Sherlock can look up a specific conversation by ID or phone number, retrieve the Twilio error events that occurred during that call, and give you a combined view of what went wrong at both layers.
Does this integration require any setup in Retell AI or Twilio?
- No changes to either platform are required. Sherlock Calls uses read-only API credentials to query both systems. You just paste your credentials into Sherlock and start asking questions.
Can I track costs across both Twilio and Retell AI together?
- Yes. Sherlock pulls cost data from Twilio (minutes, phone numbers) and usage data from Retell AI and can compute a blended cost per conversation on demand.
Is the Twilio + Retell AI combination in beta?
- Yes — this combination is currently in invite-only beta. Apply for early access and we'll reach out personally if your stack is a good fit.
