Deliver an image to the signed-in buyer, spending the image's price in credits (price.credits in search_images and get_image — often 1, sometimes more) if they do not already own it. Credits buy the personal license only; the commercial license is bought with create_checkout, and this then delivers it. If they DO already own it this is free and always will be — use it freely for re-downloads, and for a fresh download link. The purchased image comes as two links, both as the photographer framed it, uncropped: download_url, 2560px WebP on the long side, which a phone or desktop fits to its own screen as a wallpaper; and print_url, the original file at full resolution (often 10–35 MB), for printing (null when unavailable). Give the person both; they expire at download_expires_at, a day out, and their account page (account_url in get_account) lists every image they own with fresh links. The picture returned inline is a 1200px copy to show them what they got. Pass full_image: true to have the full file inline as well — often 1–3 MB — only if you can accept a result that large and save it yourself. Confirm the price with the person before spending credits. An image bought wholly with free-trial credits is the screen file only: print_url is null, print_included false, and print_offer says what the print costs — the full price again, in paid credits. With the person's agreement, call again with buy_print: true to spend them (or create_checkout kind=one_off to pay by card). After a card checkout for this image it spends nothing: it answers payment_pending until the payment lands, then delivers. Requires sign-in.

Return a payment link for the person to open in a browser: either a subscription plan, or a single image bought outright (only where price.card_available is true) — or that image's commercial license, with licence=commercial, where price.commercial is not null. The commercial license is sold only this way; Stripe's page asks the person to name the licensee. THE AGENT NEVER HANDLES CARD DETAILS and must not ask for any — hand the url over and let the person pay on the payment page. Nothing is granted until they finish. After a one-off, call fulfil_image with the same listing_id: once the payment has landed it delivers the image at no credit cost, and until then it answers payment_pending. After a subscription, get_account shows it. Every result lists the plans with their prices. Use fulfil_image instead when the buyer already has credits or already owns the image, and start_trial when they have none and have not tried the store. Refused when the buyer already owns the image or already has a subscription, so that nobody pays twice — except an image the free trial bought, which is the screen file only: a one-off for it buys the print file at the full price. Each new link cancels the previous one — any earlier subscription link, or an earlier link for the same image — so give the person only the latest.

The full terms an image is sold under: what the buyer may and may not do with it. Read this before recommending a purchase, and whenever the person asks what they are allowed to do with an image. "personal" (the default) is what credits and a card one-off buy; "commercial" is the business licence, sold by card where price.commercial is offered.

Give the signed-in buyer 3 credits free, once per email address, ever, and never to an account that has paid here. Offer it when get_account says trial_available, someone wants an image, has no credits and has not tried the store before — AND the trial would buy that image: its price.credits is no more than 3 and price.trial_credits_accepted is true. Otherwise the trial is spent on nothing they wanted. Trial credits buy the screen file only — tell the person, so a print is not expected; the print can be bought afterwards at the full price. Requires sign-in.

Open a PRIVATE collection to the signed-in buyer, using the address and access code its photographer gave them — for example a wedding or client gallery whose pictures are also for sale. Afterwards search_images, get_image and list_collections include it for this buyer, and its images can be bought like any other. Use it only with a code the person gave you; never guess one. Requires sign-in.

The signed-in buyer: their credit balance, subscription status, how many images they already own, and whether a free trial is still available. Call this before proposing a purchase, so you know what they can already afford. Requires sign-in.

Everything known about a single listing: its description, keywords, price in credits and money, the license it sells under, and a preview. Use after search_images when the person wants a closer look at one option.

The collections available in the store, with how many images are in each. Use for browsing when there is no particular search in mind; prefer search_images when the person has described what they want.

Everything the signed-in buyer has bought, newest first. Re-downloading any of them with fulfil_image costs nothing. Pass include_previews: true whenever the person wants to see their library: small pictures (at most 12 per page) without a fulfil_image per image. Requires sign-in.

Find images for sale by description, mood, colour or subject — a plain description of the feeling or scene works as well as a keyword, so pass what the person actually said. Give target_width and target_height when the image is destined for a specific screen — results are then ranked by how close each frame is to that shape, and frames whose shape is badly wrong for it (a landscape frame for a phone) are left out. Images are sold as the photographer framed them, never cropped. Returns a preview of each image. Use get_image for one listing you already have the id of; use list_collections to browse rather than search.
