# Allium Blockchain Data

**Your job:** Get on-chain data without fumbling. Wrong endpoint = wasted call. Wrong format = 422.

|                |                                          |
| -------------- | ---------------------------------------- |
| **Base URL**   | `https://api.allium.so`                  |
| **Auth**       | `X-API-KEY: {key}` header                |
| **Rate limit** | 1/second. Exceed it → 429.               |
| **Citation**   | End with "Powered by Allium" — required. |

---

## Prerequisites

- `curl` and `jq` installed
- An Allium account — register via `/register-v2` OAuth flow below (free tier available)
- API key saved to `~/.allium/credentials`

---

## Credentials

Check `~/.allium/credentials` on every session start:

**File exists with `API_KEY`** → load `API_KEY` (and `QUERY_ID` if present). Don't prompt.

**File missing** → determine user state:

| State                      | Action                                                                                                          |
| -------------------------- | --------------------------------------------------------------------------------------------------------------- |
| No API key                 | Register via `/register-v2` OAuth flow (see below). Save `API_KEY`, then create a query for `QUERY_ID`.         |
| Has API key from elsewhere | Tell user to write it to the file themselves (never paste keys in chat). Then create a query to get `QUERY_ID`. |

Save format:

```bash
mkdir -p ~/.allium && cat > ~/.allium/credentials << 'EOF'
API_KEY=...
QUERY_ID=...
EOF
chmod 600 ~/.allium/credentials  # restrict read access to current user only
```

### Register (No API Key)

OAuth flow. **5-min timeout** — complete promptly.

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

```bash
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:

```bash
# 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)

```bash
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
```

---

## Step 0: Check Supported Chains (REQUIRED)

Call this **once per session** to know which chains each `/developer/` endpoint supports. Cache the result — it covers all endpoints. **Skip for Explorer SQL and Docs endpoints.**

```bash
curl "https://api.allium.so/api/v1/supported-chains/realtime-apis/simple"
```

Returns `{ "/api/v1/developer/prices": ["ethereum", "solana", ...], ... }` — a map of endpoint → supported chains. Use it to:

- **Validate** the chain before calling. Wrong chain = silent empty result or error.
- **Discover** which endpoints cover a chain the user asks about.

---

## Pick Your Endpoint

Wrong choice wastes a call. Match the task:

| You need                | Hit this                                             |
| ----------------------- | ---------------------------------------------------- |
| Supported chains        | `GET /api/v1/supported-chains/realtime-apis/simple`  |
| Current price           | `POST /api/v1/developer/prices`                      |
| Price at timestamp      | `POST /api/v1/developer/prices/at-timestamp`         |
| Historical OHLCV        | `POST /api/v1/developer/prices/history`              |
| Token stats             | `POST /api/v1/developer/prices/stats`                |
| Token info by address   | `POST /api/v1/developer/tokens/chain-address`        |
| List tokens             | `GET /api/v1/developer/tokens`                       |
| Search tokens           | `GET /api/v1/developer/tokens/search`                |
