Quickstart

1. Get credentials

After your merchant account is opened, the platform provides:

Credential	Purpose
API key + API secret	Sign API requests. The secret is shown only once — store it safely. Create keys per scope (read / deposit / withdraw) and bind an IP allowlist
Webhook URL + webhook secret	We sign every event we push to your URL with the webhook secret; verify it on your side

Base URL: https://api.dtpg.net

2. Your first request

List supported chains. Every request carries 4 signature headers — see Authentication; ready-made code is in Code examples.

# 1. Your credentials
API_KEY="your-api-key"
API_SECRET="your-api-secret"

# 2. This request
METHOD="GET"
URI_PATH="/v1/chains"
QUERY=""                                # canonical query string; empty if none
BODY=""                                 # request body; empty for GET
TIMESTAMP=$(( $(date +%s) * 1000 ))     # now, Unix milliseconds
NONCE=$(openssl rand -hex 16)           # 32-char random string

# 3. String to sign: 6 parts joined by newlines
BODY_HASH=$(printf '%s' "$BODY" | openssl dgst -sha256 | awk '{print $NF}')
STRING_TO_SIGN=$(printf '%s\n%s\n%s\n%s\n%s\n%s' \
  "$METHOD" "$URI_PATH" "$QUERY" "$TIMESTAMP" "$NONCE" "$BODY_HASH")

# 4. Signature = hex(HMAC-SHA256(API secret, string to sign))
SIGNATURE=$(printf '%s' "$STRING_TO_SIGN" | openssl dgst -sha256 -hmac "$API_SECRET" | awk '{print $NF}')

# 5. Send it
curl "https://api.dtpg.net${URI_PATH}" \
  -H "X-Api-Key: $API_KEY" \
  -H "X-Timestamp: $TIMESTAMP" \
  -H "X-Nonce: $NONCE" \
  -H "X-Signature: $SIGNATURE"

{ "chains": [{ "code": "TRON", "name": "TRON" }] }

3. Typical integration

1. Assign a deposit address: POST /v1/wallets/{user_id}/addresses (idempotent — safe to call before every display).
2. Wait for the deposit.confirmed webhook: dedupe by event_id, then credit the user. Missed one? Backfill with GET /v1/events.
3. Create a withdrawal: POST /v1/withdraws with your own order number as biz_id (idempotency key).
4. Track it: webhooks withdraw.broadcasted → withdraw.confirmed (or withdraw.failed / withdraw.rejected), or poll GET /v1/withdraws/{withdraw_id}.

For AI / coding assistants

Give /llms-full.txt or /openapi.yaml to your AI assistant and it can write the integration for you. Every page also has a "Copy as Markdown" button under its title.
