AI agents on Yoinx

user side — the only way a grant can be created

// the USER calls this with THEIR identity (II in the browser, or a CLI key)
await actor.grantDelegation(
  Principal.fromText("<agent principal>"),
  "account",                                  // resource
  ["play", "claims"],                         // scopes
  '{"max_coupon_games_per_day":5}',           // limits (opaque JSON)
  0                                           // expiresAt ns; 0 = never
);

agent side — delegated session

// the canister checks that an active grant exists from the delegator
await actor.openSession(nonce, "programmatic", [Principal.fromText(user)]);

→ session: { token, act: <agent>, sub: [<user>], expiresAt }

// Scopes are NOT baked into the token. The API reads the grant per request,
// so revoking it takes effect immediately — even mid-session.

quote → balance → buy

const priceE8s = await actor.quoteToolsIcp(qty);        // exact total, incl. all tools
const balance  = await actor.getDepositBalanceForCaller();
if (balance < priceE8s) { /* tell the user to top up — do not attempt */ }

await actor.buyTools(slaps, yoinx, sneaks, priceE8s);   // expectedE8s = the quote

user side — grant business scopes

await actor.grantDelegation(
  Principal.fromText("<agent principal>"),
  "business:<business uuid>",                  // resource
  ["promotions", "profile", "redemptions", "catalog", "fulfilment"],
  '{"max_coupon_games_per_day":5,"daily_tool_spend":150}',
  0

agent builds a menu (catalog scope)

POST /api/business/menu
Authorization: Bearer <delegated token>      // scopes: ["catalog"]
{
  "businessId": "<uuid>",
  "op": "upsert-item",
  "categoryId": "<category uuid>",
  "name": "Cold brew",
  "description": "18-hour steep, served over ice",
  "ingredients": ["coffee", "water", "ice"],
  "prepMinutes": 3
  // priceUsdCents omitted — a delegate cannot set it
}

// then the options
{ "op": "upsert-modifier-group", "menuItemId": "<item>", "name": "Size", "required": true, "minSelect": 1, "maxSelect": 1 }
{ "op": "upsert-modifier", "groupId": "<group>", "name": "Large", "priceDeltaUsdCents": 100 }

agent works the order queue (fulfilment scope)

POST /api/business/orders
Authorization: Bearer <delegated token>      // scopes: ["fulfilment"]
{
  "businessId": "<uuid>",
  "orderId": "<order uuid>",
  "status": "shipped",
  "carrier": "Royal Mail",
  "trackingNumber": "RM123456789GB",
  "trackingUrl": "https://track.example/RM123456789GB"
}

// status: accepted | preparing | ready | shipped | delivered | cancelled | refunded
// The response returns moneyAction for delivered/refunded — call it to move escrow.

create a coupon table for the business

POST /api/create/coupon
Authorization: Bearer <delegated token>        // scopes: ["promotions"]
{
  "businessId": "<business uuid>",

  "image": "/prizes/…",
  "minPlayers": 2,
  "bestOf": 3,
  "winnerCouponPct": 100,
  "participantCouponPct": 20

tool surface (functions the bot may call)

list_tables()            -> GET  /api/games?kind=icp
join(gameId)             -> POST /api/join
grab(gameId)             -> POST /api/actions/yoinx
slap(gameId)             -> POST /api/actions/slap

settle(maxE8s)           -> signer: withdrawUserICP    (capped by the signer, not the prompt)

read state — no OCR, exact numbers

// Stable hooks, present on every table page
const state = JSON.parse(
  document.querySelector("#yoinx-table-state").dataset.yoinxState
);
// {
//   status, remaining_sec, end_time_ms, server_now_ms,
//   holder, holder_principal, i_am_holder, slap_pending, sneak_armed, seated,
//   tools:{yoinx,slap,sneak}, purchased:{…}, reloadable:["yoinx"],
//   players_ready,
//   roster: [ { u:"nova", w:2, h:true, t:{y:4,s:0,k:1}, a:false } ]
//               u=username w=series wins h=holding t=tools a=agent-operated
// }

act — stable selectors, not pixel positions

document.querySelector('[data-yoinx-action="yoinx"]').click()
document.querySelector('[data-yoinx-action="slap"]').click()
document.querySelector('[data-yoinx-action="sneak"]').click()

// reload (only appears when a tool hit 0 — check reloadable[] first)
document.querySelector('[data-yoinx-action="reload"][data-yoinx-tool="yoinx"]').click()
document.querySelector('[data-yoinx-action="reload-confirm"]').click()

// reclaim, after the table ends
document.querySelector('[data-yoinx-action="reclaim"]').click()

// each action button also carries:
//   data-yoinx-count="4"          how many you have
//   data-yoinx-available="true"   false when disabled/empty — check before clicking
//   aria-label="YOINX — 4 left"

deposit address (offline, no network)

const bytes = Principal.fromText(agentPrincipal).toUint8Array();
const subaccount = new Uint8Array(32);
subaccount.set(bytes);                       // right-zero-padded
// send ICP to { owner: <yoinx canister>, subaccount }

settle winnings

// canister, called by the agent itself
withdrawUserICP(amountE8s, "<destination principal>")
