Desktop and mobile: Developers and API users query from desks, but photographers need quick mobile access to see where their work is credited and to copy attribution text on the go. Sample screens on a computer and a phone, in the proposed brand. Their numbers are sample data.

About this appAI proposal
Bowline Photos is a search page and API for ship photographs under clear Creative Commons licences. Look up a vessel by name, IMO or MMSI number and get the image, licence, photographer's name and a source link in one response.
It is for developers and companies building maritime, logistics and shipping apps who want vessel imagery without high API fees or hand-sourcing pictures. Every photo is tied to its contributor and licence terms, so you can show the right credit.
Photographers upload their own work and keep their rights. They choose the licence, can remove a photo at any time and see where it is used. The service charges for volume and convenience, not for the pictures.

- Why this name
- A bowline is a dependable knot every sailor knows. It suggests a secure, honest link between photographers and developers.

PricingAI proposal
The material gives no competitor prices, only that existing photo APIs are called expensive. These tiers are a starting point to test, not a market-based figure.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$190,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Visible inside customers’ products. Apps using the API show the photographer credit and a small 'Photos via Bowline' link beside each image, where their own users see it.
- Do they become customers?
- Viewers are mostly end users, but some are developers or photographers. Test whether credit links lead to API sign-ups and new contributors.
- First customers
- Solo and small-team developers building vessel tracking, port or shipping tools who currently pay for photo access or collect images by hand.
- Where to reach them
- Hacker News: Post a Show HN with the free API and an open licence policy, as the demand was voiced there.
- Ship-spotting communities: Invite photographers to upload with their licence choice and usage reports.
- First milestone
- Fifty developers using the free API and five paying for higher limits within three months.

RisksAI inference
- DataThe product needs enough good photos to be useful. A photographer-contributed library may start thin, with poor coverage of less common vessels.
- Intellectual propertyPhotos must be uploaded by owners or truly openly licensed. Wrong licence claims or disputes need review and fast takedown.
- CommercialDevelopers may not pay if the free tier is enough, and photographers may not move away from existing platforms.
- DataMatching a photo to the right vessel depends on correct IMO or MMSI data, and the material does not name a source for that.
