Worth starting with a 'CSV cost breakdown experiment': have target users upload
Biggest risk
If users' API costs are low or they rarely do manual CSV calculations, the pain
Critical assumption (summary)
The user's pain point is strong enough and they are willing to pay for a lightweight tool, rather than solving it with a
Show objections and continue/stop
Strongest objection
OpenRouter's dashboard already has usage statistics, or the user's cost scale is too small to justify a dedicated tool.
Continue if
If interviews show users have high API spend and time-consuming manual calculation, continue developing the MVP.
Pivot if
If users generally say costs are low and Excel is sufficient, pivot to another scenario or abandon.
Show score rationale
Inferred from the keyword and expanded description, the product direction is OpenRouter multi-model API cost monitoring, but demand intensity and willingness to pay are both unverified.

“I don’t know” is fine — we give how to get evidence; we never invent interviews or payments.
02 Where the signal came from
Search interest 03 Search trend evidence
Is anyone searching? Relative interest — not monthly volume.
Trends 0–100 is relative interest, not monthly volume; 0 ≠ no demand.
Trends unchecked
Live search interest not checked yet. Conclusions below are hypotheses pending validation.
04 Business breakdown
Who needs this
Founders of one-person companies or independent developers who use OpenRouter to call multiple models
Job to be done
Quickly understand how much API cost each feature or model consumes, and receive alerts when costs are abnormal, to avoid eroding gross margin
Why they might pay
Saves time spent manually organizing CSVs each month; provides timely alerts to prevent overspending; supports pricing decisions
Alternatives
OpenRouter's official dashboard, manual CSV + Excel aggregation, cloud cost management tools (e.g., Vantage, CloudZero)
Differentiation wedge
Only build CSV import plus breakdown by model or tag plus gross margin alerts; no real-time API integration, no complex reports
OPC scope
Deliverable this week: a web page where users upload an OpenRouter CSV, automatically aggregate costs by model and custom tags, and show each feature's share of revenue (with user-defined gross margin threshold).
Open questions
- Will users tag requests with feature labels, or should the tool infer from the model automatically?
- Does the OpenRouter CSV contain enough information (e.g., request path, tags)?
- How do users want to be notified when an alert triggers (email, Slack)?

Talking points
- How one-person companies can prevent API costs from eating into gross margin
- The hidden costs in OpenRouter multi-model bills
- A 5-minute method for breaking down API costs with CSV

How should I read the score?
Current OPC feasibility score is 6/100. It is an AI-assisted executability check, not a market guarantee. Low scores mean “prove demand first,” not “never build.”
07 Evidence & boundaries
Demand evidence summary
Currently, only the user-described manual CSV scenario serves as the demand starting point; external evidence and payment evidence are missing.
