Install Jentic One Beta
Connect the Twilio SendGrid Email Address Validation API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Twilio SendGrid Email Address Validation API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fsendgrid.com%2Ftwilio-sendgrid-email-address-validation-api" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fsendgrid.com%2Ftwilio-sendgrid-email-address-validation-api" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Twilio SendGrid Email Address Validation API by hand means learning its bearer auth where the API key is the token, calling api.sendgrid.com, and tracking validation jobs yourself. Through Jentic you install once, import the Twilio SendGrid Email Address Validation API from the API Directory, store the key once, and your agent calls it.
Permission scoping
This API validates addresses by request body and puts the job id in the URL path (/v3/validations/email/jobs/{job_id}), so scoping stays operations-only: limit the agent to the operations it needs, such as validating an email or reading a job. You choose the operations it may call, so anything you do not add is unreachable.
Credential isolation
Your Twilio SendGrid Email Address Validation API key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'validate an email' or 'check a validation job', and Jentic returns the matching Twilio SendGrid Email Address Validation API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

What authentication does the Twilio SendGrid Email Address Validation API use?
The Twilio SendGrid Email Address Validation API uses a Bearer token in the Authorization header. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.
Can I validate an email with the Twilio SendGrid Email Address Validation API?
Yes. Use the POST /v3/validations/email endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Twilio SendGrid Email Address Validation API?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I validate an email through Jentic?

Jentic returns the matching Twilio SendGrid Email Address Validation API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Twilio SendGrid Email Address Validation API have?
The Twilio SendGrid Email Address Validation API exposes 4 endpoints covering email address validation, bulk email address validation operations.
Can I limit what my agent is allowed to do with the Twilio SendGrid Email Address Validation API?
Yes. Because you run Jentic One yourself, your own rules decide which operations and credentials the agent may use, and scoping here is operations-only. You add only the calls the agent needs, such as POST /v3/validations/email to validate an address or GET /v3/validations/email/jobs/{job_id} to read a single bulk job, while leaving out bulk upload operations like the presigned-URL request if the agent should not touch them. Anything you do not add stays unreachable, so the agent cannot call operations you never granted.
