Read-Only, Agentless Cost Monitoring

See the workflow in practice.
Read-only access, with nothing to install.
Billing integrations read cost and usage data without changing your provider resources. Permissions vary by provider; follow its setup guide. Claude usage uses opt-in OpenTelemetry, and custom sources use cost imports or scoped ingestion rather than a billing API.
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.
Team plan and above
How it worksProduct examples are illustrative. Usage estimates and provider-reported costs are separate measures; availability varies by connected source.
Explore the data viewWhy is this spend hard to control?
- 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.

The workflow
- 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.
The source
Billing and usage from your connected providers. Credential types and permission controls vary by provider.
Provider connection guidesThe limits
Provider reporting and scheduled sync determine freshness. Available history and attribution vary by source; review the setup guide for coverage. Alerts notify your team; they do not block requests or enforce a spending cap.
What we 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
Who is this for?
- 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.
Evaluation checklist
- 01
Start a trial
Open a StackSpend workspace with no credit card required.
- 02
Connect with read-only access
Use the setup guide to connect the provider or workflow with the minimum permissions needed.
- 03
Review the first 90 days
Check history, alerts, anomalies, and forecast so you can decide whether the workflow is worth adopting.
How does StackSpend support this workflow?
Native tools provide provider-specific reporting and controls. StackSpend adds a shared monitoring workflow across connected sources.
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
What do you get when you connect?
- Setup time
- Most teams can connect and validate setup in about 5-10 minutes.
- Access model
- Read-only credentials only. StackSpend does not modify provider resources or billing settings.
- Signals
- Daily Slack or email updates, anomaly alerts, and budget tracking in one workflow.
- History and forecast
- Historical spend context plus pace-to-forecast so overruns are visible before month-end.

When is this workflow useful?
- 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
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.
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.
