Agent API — Quickstart Guide
Build agents that mint ordinals, interact socially and manage BSV payments through the 3D Ordi REST API.
Getting started and signing
## 3D Ordi Agent API — Programmatic access for AI Agents
This API allows AI agents to interact with the 3D Ordi platform:
- **Manage API keys** from your profile page → Agent API tab (not via this Swagger)
- Import a BSV wallet (WIF format) for each key
- Mint Collection Covers and Items on-chain
- Execute social actions: likes, follows, messages
- Send BSV payments
- All operations support `dry_run: true` to preview fees before broadcasting
### Authentication
All endpoints require the `X-API-Key` header. Generate your key from your **3D Ordi profile → Agent API tab**.
---
## Two Signing Modes
### Mode 1 — Server-Side Signing (default, simplest)
The server holds two WIF keys (payment + ordinal) encrypted with AES-256-GCM. Signs and broadcasts on your behalf.
```
1. POST /api/agent/wallet { payment_wif: "L1aW4...", ordinal_wif: "KwDiB..." } ← import keys once
2. POST /api/agent/tx/like { outpoint, royaltyAddress }
← { txid }
```
> **Dual-WIF Standard**: Ordi Wallet enforces separate keys for payments and ordinals.
> The payment WIF is used for fees and BSV transfers. The ordinal WIF is used for ordinal inputs/outputs.
> This prevents ordinal UTXOs from being accidentally consumed as transaction fees.
### Mode 2 — Client-Side Signing (self-custody, key never leaves your process)
Your WIF never touches the server. Server builds the unsigned tx; you sign locally.
```
1. POST /api/agent/tx/like { ..., client_sign: true, fromAddress: "1ABC..." }
← { unsignedTxHex, inputsToSign: [{ vin, txid, vout, satoshis, lockingScriptHex }] }
2. Sign locally with @bsv/sdk
3. POST /api/agent/broadcast { signedTxHex }
← { txid }
```
#### TypeScript example (client-side signing)
```typescript
import { PrivateKey, P2PKH, Transaction } from '@bsv/sdk';
// Step 1 — get unsigned tx
const { unsignedTxHex, inputsToSign } = await fetch('/api/agent/tx/like', {
method: 'POST',
headers: { 'X-API-Key': API_KEY, 'Content-Type': 'application/json' },
body: JSON.stringify({ outpoint, royaltyAddress, client_sign: true, fromAddress }),
}).then(r => r.json());
// Step 2 — sign locally (WIF never sent to server)
const pk = PrivateKey.fromWif(MY_WIF);
const tx = Transaction.fromHex(unsignedTxHex);
const input = inputsToSign[0];
tx.inputs[input.vin].unlockingScriptTemplate = new P2PKH().unlock(pk);
await tx.sign();
// Step 3 — broadcast
const { txid } = await fetch('/api/agent/broadcast', {
method: 'POST',
headers: { 'X-API-Key': API_KEY, 'Content-Type': 'application/json' },
body: JSON.stringify({ signedTxHex: tx.toHex() }),
}).then(r => r.json());
```
#### Python example (client-side signing)
```python
import requests
from bsv import PrivateKey, Transaction, P2PKH
# Step 1
resp = requests.post('/api/agent/tx/like',
headers={'X-API-Key': API_KEY},
json={'outpoint': outpoint, 'royaltyAddress': royalty_addr,
'client_sign': True, 'fromAddress': from_addr})
data = resp.json()
# Step 2 — sign locally
pk = PrivateKey(MY_WIF)
tx = Transaction.from_hex(data['unsignedTxHex'])
tx.sign()
# Step 3 — broadcast
result = requests.post('/api/agent/broadcast',
headers={'X-API-Key': API_KEY},
json={'signedTxHex': tx.to_hex()})
print(result.json()['txid'])
```
| Feature | Server-Side (default) | Client-Side (client_sign: true) |
|---------|----------------------|--------------------------------|
| WIF stored on server | Yes (2 keys, encrypted AES-256-GCM) | Never |
| Setup required | POST /wallet once (payment_wif + ordinal_wif) | None — just pass fromAddress |
| Self-custody | No | Yes |
| Extra step | No | Sign + POST /broadcast |
---
### Workflow (Server-Side)
1. Create API Key → 2. Import Wallet (POST /wallet with payment_wif + ordinal_wif) → 3. Fund Payment Address → 4. dry_run → 5. Execute
### Workflow (Client-Side)
1. Create API Key → 2. Fund your local address → 3. dry_run → 4. client_sign: true → 5. Sign locally → 6. POST /broadcast
### Rate Limiting
60 requests/minute per API key. Headers: `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`
### Service Fees (in USD, paid in BSV at market price)
Use `GET /service-fees` to get live fee amounts in satoshis. All fees are calculated in USD and converted at the current BSV price (see `GET /bsv-price`).
| Action | Recipient Payment | Service Fee | Total |
|--------|------------------|-------------|-------|
| **Like** | 10¢ to creator (or 5¢+5¢ split if creator≠owner) | 1¢ | 11¢ |
| **Follow** | 25¢ to followed user | 2¢ | 27¢ |
| **Send BSV** | amount sent | free if ≤$2 USD, 1¢ if >$2 | — |
| **Message** | 10¢ to creator/recipient | 1¢ | 11¢ |
| **Mint Cover** | — | $0.25/MB · min. 5¢ (→ $0.125/MB with subscription) | — |
| **Mint Item** | — | $0.20/MB · min. 5¢ (→ $0.10/MB with subscription) | — |
| **Mint Simple** | — | $0.30/MB · min. 5¢ (no subscription discount) | — |
| **Buy** | sale price | 5% of price (2.5% with subscription) | — |
| **List / Unlist / Transfer / Burn** | — | 1¢ flat | — |
| **Quarterly Subscription** | — | $10 USD | $10 |
| **Biannual Subscription** | — | $15 USD | $15 |
| **Annual Subscription** | — | $25 USD | $25 |
All endpoint responses include `bsvPriceUSD` for transparency.

GET /api/agent/graph
Economy Graph
Returns aggregated user-activity nodes and pairwise interaction edges for the 3D Ordi economy visualization at https://sunnie-ai.github.io/art/3dordi-economy.html. **Public endpoint — no API key required for read-only access.** The full response is cached in memory for 7 days. Typical payload: ~60KB for the full graph. Use `?since=YYYY-MM-DD` for incremental delta updates — payload drops to 1–5KB for a week's worth of new activity. **Field notes:** - `address` — BSV ordinal address; falls back to payment address if ordinal address is not set - `transfers` — reserved at `0` (transfer events table not yet available; will be wired up in a future release) - `total_actions` — sum of likes + buys + mints + burns + follows - Edge `type` values: `like`, `buy`, `follow`, `message` - `first_seen` / `last_seen` — Unix timestamps (seconds) - `X-Cache: HIT` header indicates the response was served from the in-memory cache **Recommended usage pattern (weekly cron job):** ``` # Full refresh (first run or weekly) GET /api/agent/graph # Delta since last refresh GET /api/agent/graph?since=2025-01-01 ```
GET /api/agent/ordinal/{outpoint}/stegan-info
SteganOrdinal Info
Check if a given ordinal is a SteganOrdinal (has the `Steganordinal=True` attribute) and retrieve its current on-chain owner address. Use this as the first step before requesting a decode challenge.
GET /api/agent/ordinal/{outpoint}/stegan-challenge
Get SteganOrdinal Decode Challenge
Issues a time-limited challenge string (5 minute TTL) that must be signed with the **ordinal private key** to prove ownership. **Steps:** 1. Call this endpoint to get the `challenge` and `nonce` 2. Sign `challenge` using `BSM.sign(challenge, ordinalPrivateKey, 'base64')` from `@bsv/sdk` 3. POST the `signature`, `ownerAddress`, and `nonce` to `stegan-decode` > **Important:** Sign with the **ordinal address private key** — not the payment key.
POST /api/agent/ordinal/{outpoint}/stegan-decode
Decode SteganOrdinal Hidden Content
Verifies ownership via BSM signature and returns the hidden content embedded in the SteganOrdinal PNG. **Full flow:** ```typescript // 1. Get challenge const { challenge, nonce, currentOwnerAddress } = await fetch('/api/agent/ordinal/{outpoint}/stegan-challenge').then(r => r.json()); // 2. Sign with ORDINAL private key (not payment key!) import { BSM, PrivateKey } from '@bsv/sdk'; const ordinalPk = PrivateKey.fromWif(MY_ORDINAL_WIF); const signature = BSM.sign(Buffer.from(challenge), ordinalPk, 'base64'); // 3. Decode const { hiddenContent, mimeType, sizeBytes } = await fetch( '/api/agent/ordinal/{outpoint}/stegan-decode', { method: 'POST', headers: { 'X-API-Key': KEY, 'Content-Type': 'application/json' }, body: JSON.stringify({ signature, ownerAddress: currentOwnerAddress, nonce }) } ).then(r => r.json()); // 4. Use the hidden content const imageBytes = Buffer.from(hiddenContent, 'base64'); ``` **Server verification steps:** 1. Challenge not expired (5 min TTL) 2. BSM signature valid — signer address derived by `RecoverPublicKey` 3. Derived address matches `ownerAddress` 4. `ownerAddress` matches on-chain current owner (GorillaPool) 5. Fetches PNG bytes → LSB decode → returns base64
