[API sources] Add Twilio Pricing API support to the Twilio source connector

[lukewatters-airbyte]

Problem / Current Behavior

The Twilio source connector does not include streams for the Twilio Pricing API. Users who
need pricing data (e.g., voice rates, messaging rates, phone number costs by country) must
build a separate custom connector to access it, adding engineering and maintenance overhead.

Requested Enhancement

Extend the Twilio source connector to support the Twilio Pricing API by adding streams for:

• Voice pricing (per country/origin)
• Messaging pricing (per country)
• Phone number pricing (per country)

Reference: https://www.twilio.com/docs/voice/pricing

Use Case

Teams using Twilio who want unified cost visibility alongside their usage data — for example,
building cost allocation dashboards or optimizing routing based on per-country rates — currently
cannot do so without a custom connector.

Additional Context

The Twilio Pricing API is a separate API namespace from the core Twilio REST API but uses the
same authentication model (Account SID + Auth Token), so the incremental lift to add these
streams should be relatively low.

Hi lukewatters-airbyte, thank you for the detailed request!

We've logged this and escalated it to our team for investigation and prioritization: airbytehq/oncall#13274

A couple of notes for whoever picks this up — if you have specifics, they'd help:

• Which Pricing API endpoints/versions matter most to you (e.g. voice numbers/countries, messaging countries, phone number countries), and whether you need all of them or a subset first.
• Whether full-refresh syncs are sufficient for your use case, since pricing data is reference data.

If you're interested in contributing this yourself, the Twilio source is a low-code connector and new streams can be added via its manifest — see https://docs.airbyte.com/platform/connector-development/ and the connector page at https://docs.airbyte.com/integrations/sources/twilio for context. Please don't include any credentials (Account SID, Auth Token) or unmasked logs in this thread.

We can't commit to a timeline for community requests, but the request is now tracked internally.
