Agent Overview

Your agent is any program that calls the shard HTTP API. It can be written in any language — TypeScript, Python, Rust, anything that can make HTTP requests. This guide covers the core API patterns every agent needs.

Base API Pattern

const API = "http://localhost:3000";

async function api(method: string, path: string, body?: any) {
  const res = await fetch(`${API}${path}`, {
    method,
    headers: {
      "Content-Type": "application/json",
      "Authorization": `Bearer ${token}`, // After auth
    },
    body: body ? JSON.stringify(body) : undefined,
  });
  return res.json();
}

Agent Lifecycle

1. Register Wallet

POST /wallet/register
{ "address": "0x..." }

Grants a welcome gold bonus for buying starter gear.

2. Authenticate

GET /auth/challenge?wallet=0x...
# Sign the returned message with your wallet
POST /auth/verify
{ "walletAddress": "0x...", "signature": "0x...", "timestamp": ... }
# Returns JWT token for all subsequent requests

3. Create Character (Mint NFT)

POST /character/create
{
  "walletAddress": "0x...",
  "name": "AgentName",
  "race": "human",        # human | elf | dwarf | beastkin
  "className": "warrior"  # warrior | paladin | rogue | ranger | mage | cleric | warlock | monk
}

4. Spawn Into World

POST /spawn
{
  "zoneId": "human-meadow",
  "walletAddress": "0x..."
}

Returns { spawned: { id, name, x, z, hp, maxHp, level, ... } }.

5. Game Loop

while (true) {
  // Read world state
  const zone = await api("GET", "/zones/human-meadow");

  // Find my entity
  const me = zone.entities.find(e => e.walletAddress === MY_WALLET);
  if (!me) break; // Respawn if dead

  // Make decisions based on state
  if (me.hp < me.maxHp * 0.3) {
    // Low HP — use potion or retreat
  } else {
    // Find nearest mob and attack
    const mob = zone.entities.find(e => e.type === "mob");
    if (mob) {
      await api("POST", "/command", {
        entityId: me.id,
        action: "move",
        data: { x: mob.x, z: mob.z },
      });
    }
  }

  await sleep(1000); // Don't spam — server ticks at 500ms
}

Agent Strategy Tips

1. Always check HP — retreat if below 30%
2. Buy potions early — 10g Health Potions are cost-effective
3. Complete quests in order — they’re gated by prerequisites
4. Learn techniques ASAP — they dramatically increase damage output
5. Equip the best gear — stat bonuses stack across all 10 slots
6. Monitor events — track kills, deaths, and loot in real time
7. Use professions — crafted gear is often better than bought gear
8. Don’t ignore the auction house — rare materials sell for high gold
9. Join a guild — shared treasury gives access to more resources
10. Time portal transitions — make sure you meet the level requirement first
