How does StackSpend handle Read-Only, Agentless Cost Monitoring?
A cost monitoring tool should never need write access or an agent. StackSpend connects to each provider with read-only billing credentials — AWS Cost Explorer, GCP BigQuery billing export, Azure Cost Management, and read-only API keys for AI providers — and can only read spend and usage data. It cannot create, modify, or delete resources, it does not run an agent in your accounts, and it never receives application data, prompt or completion content, logs, or customer records. Credentials are encrypted with AES-256, each organisation is isolated at the data layer, configuration changes are captured in an audit log, and data export and deletion are self-service.
How does it work in practice?
- 01
Every connection is read-only and scoped to billing and usage data, per provider, and StackSpend cannot change anything in your accounts.
- 02
There is no agent. Nothing is installed in your environment; billing APIs are read from outside, so the integration's blast radius is the billing data itself.
- 03
Cost data only — no application data, prompt or completion content, customer records, or logs.
- 04
AES-256 at rest, TLS in transit, per-organisation isolation, an audit log of configuration changes, and self-service export and deletion.
What makes this work?
Read-only access, with nothing to install.
Every integration reads billing and usage APIs with the least privilege the provider allows. No agents, no write scopes, no infrastructure changes, and you can tell your security reviewer exactly what was granted.
How it worksCatch the spike the day it starts.
StackSpend learns what normal looks like per provider, account and service, then flags the day something breaks pattern, with a severity and an owner. Each one carries a lifecycle, so it gets closed.
How it worksOne message each morning. Nobody opens a billing portal.

Read-only · 5 minutes per provider
Who uses this?
- Teams that want daily visibility into spend without manually checking billing portals.
- Buyers replacing spreadsheets and fragmented native dashboards with one monitoring workflow.
- Operators who need read-only setup, alerts, and forecasting before overrun becomes month-end reality.
What does StackSpend track?
- Read-only billing and usage data only
- No agent, nothing installed in your accounts
- No application data, prompt content, or customer records
- AES-256 at rest, TLS in transit
- Per-organisation tenant isolation
- Audit logging of configuration changes
- Self-service export and deletion
When does this use case fire?
- A security review stalls a purchase because nobody can state which scopes the tool requests
- An agent-based tool is rejected late for widening the production blast radius
- A vendor questionnaire asks where cost data is stored and how it is deleted
- An AI provider key is issued with full access because read-only scoping was never checked
Giving a third party billing access is a security decision, and it is usually the last gate before a purchase — signed off by someone who did not ask for the tool.
Most vendors answer "is it secure?" with a badge rather than the specific scopes they request, so the reviewer reverse-engineers the answer.
Agent-based tooling runs inside your accounts, which widens the blast radius and lengthens the review.
"What happens to our data if we leave?" is rarely answerable from a pricing page.
How does StackSpend do this?
Agent-based and write-access cost platforms is built for different jobs. Here is what StackSpend adds.
Agent-based and write-access cost platforms
- An agent inside your accounts widens the blast radius and lengthens review
- Write or optimisation permissions mean the tool can change infrastructure
- Platforms ingesting logs or traces receive far more than billing data
- Deletion and export are often a support request
StackSpend
- Read-only billing scopes, stated per provider, nothing installed
- Cost data only — no application data or customer records
- Tenant isolation, AES-256, and an audit log
- Self-service export and deletion
Native tools show you last month. StackSpend tells you tomorrow.
Read-Only, Agentless Cost Monitoring starts from day one — no manual setup and no threshold tuning required.

Read-Only, Agentless Cost Monitoring, answered
Is it safe to give a cost monitoring tool billing access?
It is, provided the access is read-only and scoped to billing data. StackSpend connects with read-only credentials per provider — AWS Cost Explorer, GCP BigQuery billing export, Azure Cost Management, and read-only API keys for AI providers — so it can read what you were charged but cannot create, modify, or delete any resource. Nothing is installed in your environment, and it never receives application data, prompt or completion content, logs, or customer records.
What permissions does each provider connection need?
AWS: read-only access to Cost Explorer, plus Organizations for multi-account estates. GCP: read access to a BigQuery billing export dataset. Azure: reader on the Cost Management API. AI and SaaS providers: a read-only or usage-scoped API key where one is offered. In every case the credential is scoped to billing and usage, never to workloads or data planes.
Does StackSpend need an agent in our accounts?
No. Nothing is installed in your environment and nothing runs inside your accounts — provider billing APIs are read from outside, so the blast radius of the integration is the billing data itself. That is usually the difference between a short security review and a long one.
