Allium Onchain Data

Save format:

mkdir -p ~/.allium && cat > ~/.allium/credentials << 'EOF'
API_KEY=...
QUERY_ID=...
EOF

Register (No API Key)

OAuth flow. 5-min timeout — complete promptly.

1. Ask user for name and email (one prompt).
2. POST to initiate:

curl -X POST https://api.allium.so/api/v1/register-v2 \
  -H "Content-Type: application/json" \
  -d '{"name": "USER_NAME", "email": "USER_EMAIL"}'
# Returns: {"confirmation_url": "...", "token": "..."}

3. Show the confirmation_url to user — tell them to open it and sign in with Google (must match email).
4. Auto-poll immediately — don't wait for user to confirm. Start a background polling loop right after showing the URL:

# Poll every 5s until 200 or 404. Run this in background immediately.
TOKEN="..."  # from step 2
while true; do
  RESP=$(curl -s -w "\n%{http_code}" "https://api.allium.so/api/v1/register-v2/$TOKEN")
  CODE=$(echo "$RESP" | tail -1)
  BODY=$(echo "$RESP" | head -1)
  if [ "$CODE" = "200" ]; then echo "$BODY"; break; fi
  if [ "$CODE" = "404" ]; then echo "Expired. Restart."; break; fi
  sleep 5
done
# 200 body: {"api_key": "...", "organization_id": "..."}

5. On 200 — save API_KEY to ~/.allium/credentials, then create query below for QUERY_ID. No user prompt needed between poll and save.

Create Query (Has API Key, No query_id)

curl -X POST "https://api.allium.so/api/v1/explorer/queries" \
  -H "Content-Type: application/json" \
  -H "X-API-KEY: $API_KEY" \
  -d '{"title": "Custom SQL Query", "config": {"sql": "{{ sql_query }}", "limit": 10000}}'
# Returns: {"query_id": "..."}
# Append to ~/.allium/credentials

Before Calling Developer Endpoints

Read references/realtime/overview.md first — it covers supported chains discovery, error codes, and common gotchas that apply across all realtime endpoints.

Pick Your Endpoint

Wrong choice wastes a call. Match the task:

Common Tokens

Don't guess addresses. Use these:

Chain names are lowercase. ethereum, base, solana, arbitrum, polygon, hyperevm. Uppercase fails silently.

Quick Examples

Current Price

curl -X POST "https://api.allium.so/api/v1/developer/prices" \
  -H "Content-Type: application/json" \
  -H "X-API-KEY: $API_KEY" \
  -d '[{"token_address": "0xcbb7c0000ab88b473b1f5afd9ef808440eed33bf", "chain": "ethereum"}]'

Historical Prices (Last 7 Days)

Format matters. Not token_address + chain — use addresses[] array:

END_TS=$(date +%s)
START_TS=$((END_TS - 7*24*60*60))

curl -X POST "https://api.allium.so/api/v1/developer/prices/history" \
  -H "Content-Type: application/json" \
  -H "X-API-KEY: $API_KEY" \
  -d "{\"addresses\": [{\"token_address\": \"0xcbb7c0000ab88b473b1f5afd9ef808440eed33bf\", \"chain\": \"ethereum\"}], \"start_timestamp\": $START_TS, \"end_timestamp\": $END_TS, \"time_granularity\": \"1d\"}"
