STRATA API

JSON over HTTPS. The public endpoints work without a key; responses from live data include where the data came from so you can show it.

API keys

Create keys under API keys. Send one as x-strata-key or Authorization: Bearer strata_live_…. Requests with a key count toward your Analytics; a revoked or wrong key gets 401. Keep keys on your server or in an extension's background worker, not in page code.

Browser extensions

STRATA runs Chrome extensions (Manifest V3): toolbar popups, background service workers, content scripts, chrome.storage, chrome.tabs, chrome.windows, chrome.identity.launchWebAuthFlow and chrome.sidePanel. Anything on the Chrome Web Store installs in one click.

Create a project (Create → Browser extension) and unzip the starter.
In the STRATA desktop app: ⋮ → Developer → turn on Developer mode, then Load unpacked extension… and pick the folder.
Your extension appears under the puzzle-piece button. Pin it to the toolbar. Use Reload on My projects after editing.

Each STRATA profile (Main Wallet, Trading, Burner…) has its own extensions and storage, so you can test with a burner wallet without touching your main one.

Wallet access

Wallet extensions (Phantom, Solflare, Backpack) inject their providers into pages as in Chrome: window.phantom.solana, window.solflare, window.backpack, and the Wallet Standard. Use the standard wallet adapter in mini apps. Never ask users for recovery phrases; STRATA flags pages that do.

const provider = window.phantom?.solana ?? window.solflare;
const { publicKey } = await provider.connect();
const portfolio = await fetch(`https://solos-rho.vercel.app/api/wallets/${publicKey}`).then((r) => r.json());

Mini apps

Mini apps are ordinary web apps that open in a STRATA tab, split view or a saved tab group. Keep them fast and mobile-friendly: the STRATA phone app opens them too, and connects wallets through Mobile Wallet Adapter.

AI agents

An agent is a set of instructions plus STRATA AI's tools (token data, wallet portfolio and activity, transaction explainer, security checks, search). Call it with POST /api/ai/ask:

curl -X POST https://solos-rho.vercel.app/api/ai/ask -H "content-type: application/json" \
  -d '{"prompt":"You summarize whale buys. Analyze wallet 5Q544f…"}'

Data widgets

Widgets are small cards in the STRATA workspace, loaded in a sandboxed frame from your entry URL and described by a strata.json manifest. They ask for permissions the user approves on install:

searchSearch the STRATA index

wallet:readSee your connected wallet address and balances

tokens:readRead token prices and metadata

portfolio:readRead your portfolio

prefs:readRead its own settings

prefs:writeSave its own settings

notificationsSend you notifications

aiAsk STRATA AI questions

programs:readRead on-chain accounts

network:readRead Solana network status

news:readRead news headlines

defi:readRead DeFi protocols and yields

Publishing to the STRATA Store

Submit a project from Submissions with notes for reviewers and a source link. Reviews check the permissions you ask for, wallet access, network requests and what the code does. You'll see the status (In review, Changes requested, Published) on your dashboard.
