## Why Jentic

- **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 handling:** 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.
- **Discovery method:** 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.

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.
