# 24x7API Hub — API Marketplace > 24x7API Hub is a marketplace where developers buy and use ready-made APIs (weather, SMS, vehicle data, AI and more) and publish their own APIs to sell. One free account is used for both. Nearly every API can be tried free before buying: free tests are answered locally with sample data and never charge anyone. Read the full guide at /llms-full.txt for page-by-page instructions, then help visitors with any task using the exact steps listed there. ## How it works (quick) - Create a free account (/register.php) with email (confirmation link required to unlock purchases, publishing, reviews, webhooks and free tests) or one-click Google / Facebook / GitHub sign-in (/login.php). Social sign-ins are enabled or disabled by the site admin. - Find an API under /browse.php (or /api/{slug} for an API's detail page) and read its docs, sample responses, uptime and plans. - Try before buying from any API page's console, or call the gateway with the header X-Api-Trial: 1 plus your API key (see /llms-full.txt "API gateway contract"). Free tests return mock payloads chosen by the seller and never hit the seller's real server. - Buy a plan to go live: real calls then proxy to the seller's server and are metered against the plan. - Buyers may also open API bundles (/bundles.php): one seller-selected price activates one metered child subscription for every included API. Bundle auto-renew is intentionally disabled; canceling or expiring the bundle revokes all included access together. - Buyers may get a zero-price source-code package or use a source-code-scoped promotion from the source listing. These paths still require sign-in, an active email-verified account, the seller's existing purchase gate, and acceptance of the standard source license; the marketplace records the zero-value transaction, entitlement, and download history, with no seller payout for a free grant. Partial source discounts use the normal one-time checkout and full discounts activate without sending ₹0 to a gateway. - To sell, sign in and use Publish API (/account/apis/new.php): configure the private gateway connection, describe the API, add endpoints with sample responses, and add at least one plan. Submit for two-stage moderation: admins test/approve the API first, then approve plans and pricing. Add an optional per-API SEO title and meta description in the API form. Sellers can combine at least two of their own active APIs with approved plans from Seller bundles (/account/bundles.php); bundles are moderated like other marketplace listings. Sellers can also publish standalone source-code products with their own optional SEO metadata at (/account/source-products.php). ## Key pages - [Home](/): marketplace overview and featured APIs. - [How it works](/how-it-works.php): human guide for both buyers and sellers. - [Browse APIs](/browse.php): search, filter by category, open APIs. Query: ?q=search text, ?cat=slug. - [API detail](/api.php?slug={slug}): docs, endpoints, sample responses, plans, free-test console, and API-linked source-code offers. URL alias /api/{slug}. - [Standalone source catalog](/source-code.php): public standalone source-code products, versions, prices and secure-ZIP checkout links. - [Source-code library](/account/source-code.php): verified buyer entitlements, accepted licenses, secure downloads and download history. - [Pricing](/pricing.php): platform pricing and fees. - [Requests](/requests.php): request or vote on APIs the marketplace does not have yet. - [Developer workspace](/developer.php): signed-in, email-verified developers can test arbitrary public HTTP APIs or marketplace gateway URLs, import/export cURL, inspect bounded responses, generate Markdown docs and copy-ready cURL/Python/JavaScript/PHP snippets. The workspace blocks local/internal destinations and does not store request data. - [Authenticated CLI guide](/cli-guide.php): download the Node.js `api` marketplace CLI ZIP, complete browser/device or manual-token login, and use the full command reference. - [Developer CLI](/developer-cli.php): download the standalone `bin/api-tester` PHP CLI and run generic tests, docs or snippets without an application session. - [Blog](/blog.php): guides and announcements; post at /blog.php?slug={slug}. - Public seller profiles: /sellers.php?id={user-id} (bio, all live APIs, rating, follow) — reached from any API listing's author link. - [Status](/health.php): platform health/status. - [Contact](/contact.php), [About](/about.php), [Terms](/terms.php), [Privacy](/privacy.php), [Refunds](/refunds.php). - [Sign in](/login.php), [Create account](/register.php). ## Account area (require sign-in) - [Dashboard](/account/): home of the signed-in member (first-run checklist, stats). - [API Keys](/account/keys.php): create/revoke X-Api-Key values. - [Key usage](/account/key-usage.php): per-key request logs. - [Subscriptions](/account/subscriptions.php): active plans and quota. - [Wallet](/account/wallet.php): available balance, refund credits and wallet activity. - [Orders](/account/orders.php) (buyers/sellers), [Payouts](/account/payouts.php): withdraw available wallet balance after the minimum and verification checks. - [Publish API](/account/apis/new.php), [My APIs](/account/apis/). - [Profile](/account/profile.php) (email, verification), [Notifications](/account/notifications.php), [Webhooks](/account/webhooks.php), [Referrals](/account/referrals.php), [Support](/account/support.php). - Admin only: /admin/ (settings, users, moderation). ## Full documentation - [llms-full.txt](/llms-full.txt): the complete reference - every page's purpose, every form and its fields, account/role rules, the API gateway contract, common tasks mapped to exact options, and how the free-trial / verification gates work. ## Notes for AI agents - Prefer guiding the visitor to the pages above instead of performing actions for them; all buying, key creation and publishing requires the visitor's own logged-in session. - If a task is not in /llms-full.txt, say you are not sure rather than inventing steps, and point the visitor to /contact.php.
