Can I get Apollo.io spend per day from the API?

Not as a series. Derive it from how much the balance drops each day, ignoring top-ups.

Enrichment

How to get your Apollo.io API usage, balance and spend programmatically

Yes, if your key is allowed to read it. POST https://api.apollo.io/api/v1/usage_stats/credit_usage_stats returns each credit pool's limit, consumed and left_over, plus the current credit cycle. The call costs 0 credits.

What the Apollo.io API exposes

Signal	Apollo.io
Balance	Yes. Apollo API (usage)
Spend history	No
Cost breakdown	No
Plan and quota	No
Cost on each response	No
Rate-limit headers	None
Credential	API key

Call it yourself

Credential. An Apollo API key with the usage stats endpoint in its scope, or a master key. A narrower key returns 403.

Credit pools

curl -X POST https://api.apollo.io/api/v1/usage_stats/credit_usage_stats \
  -H "X-Api-Key: $APOLLO_API_KEY" \
  -H "Content-Type: application/json"

{
  "credit_usage_stats": {
    "lead_credit": { "limit": 12000, "consumed": 4310, "left_over": 7690 },
    "dialer": { "limit": 500, "consumed": 32, "left_over": 468 }
  },
  "current_credit_cycle": { "start_date": "2026-10-01", "end_date": "2026-11-01" }
}

Gotchas

Auth is header-only (X-Api-Key) since September 2024. Keys in the query string or body no longer work.
On unified plans lead_credit already nets mobile, export and power-up spend. Don't add the pools together.
dialer is minutes, not credits.
Credits are weighted by operation: an email costs 1, a phone number 8.
GET /api/v1/auth/health is a free key check.

How Apollo.io charges

Per-seat plans with credits granted upfront (annual) or monthly (Free), operation-weighted (email 1, phone 8). Plus team-level feature add-ons (Inbound, Advanced Dialer).

Plan	Monthly price
Free	$0
Basic	$49
Professional	$79
Organization	$119

Free allowance. 75 a month. 900/seat/year on Free.

At zero. 402. Credits granted upfront per term; buy additional credits in-app when depleted.

Or let Argus track it

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

Reads the Apollo.io balance every hour and keeps the series, so you get burn per day (top-ups never count as negative spend) and days until it hits zero.
With the SDK, itemizes each call by endpoint and prices it at Apollo.io's per-operation rates.
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.
