Can I get SendGrid spend per day from the API?

No. Count calls and price them yourself, or let the Argus SDK do it.

How to get your SendGrid API usage, balance and spend programmatically

SendGrid has no credit balance or remaining-quota endpoint. GET /v3/user/account only tells you whether the account is free or paid; consumption has to be counted from /v3/stats against your tier.

What the SendGrid API exposes

Gotchas

The named tier (Essentials, Pro, Premier) and its email volume aren't in any API.
Overage is metered and invoiced the following month, so the bill lags the sends.
The free tier was replaced by a 60-day trial capped at 100 emails a day.

How SendGrid charges

Volume-tier subscriptions (Essentials/Pro) by included emails/month; overage metered and invoiced next month. 60-day trial replaced the free tier.

Plan	Monthly price
Free Trial	$0
Essentials (50k)	$19.95
Essentials (100k)	$34.95
Pro	$89.95
Premier	Contact sales

At zero. 429. Paid plans meter overage, invoiced the following month; trial hard-stops at 100/day.

Or let Argus track it

Paste the key once. Argus keeps the ledger, and your coding agent reads it through the MCP server.

Tracks the plan: the allowance, what's used this period, the reset date, and when you cross into overage.
With the SDK, counts each call and every 429 against the plan's allowance, since there's no meter to read.
Emails you on low balance, days to zero, a spend spike, or projected overage.
Hands all of it to your coding agent over MCP, so it can ask what a run cost or how much runway is left without leaving the editor.
