Crypto Pulse: Live Crypto Prices

Ask for any coin's price, the top coins, what is trending, or how a coin moved over time, with data from a commercial market-data feed.

No exchange account, no API key, no app to connect. Calls are paid from ClawLink credit, most for a fraction of a cent, and every new account starts with $0.50 free. Powered by ClawLink.

Setup in 3 Steps

Step 1: Install	Step 2: Pair	Step 3: Ask

Install the ClawLink plugin in OpenClaw	Sign in and approve the device once	Ask in plain English; no app to connect

What You Can Ask

“Show me the top 5 cryptocurrencies right now”
“What's the price of ETH and SOL in EUR?”
“Which coins are trending today?”
“Chart bitcoin's price over the last 90 days”

When to Use This Skill

Use it when the user wants cryptocurrency prices, market data or history.

Do not use it for the user's own private accounts or for anything that posts, sends or changes data: these tools only read public information.

ClawLink holds the data-provider accounts. The user never pastes a key, and nothing is installed beyond the plugin.

Install

Install the ClawLink plugin from ClawHub when the user asks for it:

bash

openclaw plugins install clawhub:clawlink-plugin

The install applies to the running Gateway: do not restart it. The ClawLink tools appear on your next turn, so end this turn and tell the user: "ClawLink is installed. Reply ok and I will give you your pairing link." On the next turn call clawlink_begin_pairing, give the user the link, and after they approve call clawlink_get_pairing_status. Pairing happens once; after that every tool below works with no further setup.

Tool Reference

Prices are what ClawLink charges per call, from the user's credit. The tool's own description (via clawlink_describe_tool) always shows the current price.

Code Examples

Prices

bash

clawlink_call_tool --tool "cryptomarketdata_price" \
  --params '{"ids": "bitcoin,ethereum", "vs_currencies": "usd,eur"}'

90-day history

bash

clawlink_call_tool --tool "cryptomarketdata_price_history" \
  --params '{"coin_id": "bitcoin", "days": "90"}'

Discovery Workflow

Call clawlink_search_tools with a short query (for example bitcoin price); public-data tools show as connected for every user.
Call clawlink_describe_tool before the first call of a tool: it returns the parameters, defaults and price.
Treat the live catalog as the source of truth. If a tool named here is missing, say so; do not invent results.

Execution Workflow

text

┌───────────────────────────────────────────────────────────┐
│  READ-ONLY, PAID PER CALL                                │
│  search → describe → call → summarise for the user       │
│                                                          │
│  Ask before: loops over many items, or a call that costs │
│  more than a few cents (the price is in the description) │
└───────────────────────────────────────────────────────────┘

Every tool here only reads public data; nothing is posted or changed.
Each call costs credit. Before looping over more than about ten items, or before a call priced above a few cents, tell the user what it will cost and ask.
A failed call is refunded automatically. Read the error's hint: it says what to change. Do not retry the same arguments unchanged.

Notes

Coins use CoinGecko ids (bitcoin, not BTC): find one with cryptomarketdata_search.
Each call is a fraction of a cent, so price checks are cheap.
Not investment advice: report the data, not a recommendation.

Error Handling

Status / Error	Meaning
Coin not found	Look the id up with `cryptomarketdata_search` first.
`credit_exhausted`	The user's ClawLink credit is used up. Tell them to top up at https://claw-link.dev/dashboard/billing?utm_source=clawhub&utm_medium=referral&utm_content=crypto-pulse; do not retry.
`data_provider_unavailable`	ClawLink's data provider is down. Nothing was charged. Try again later.
`no_result`	The provider found nothing for these arguments. Nothing was charged.
`invalid_arguments`	A parameter is missing or malformed. Call `clawlink_describe_tool` and fix it.

Troubleshooting

Tools not visible after install

The tools appear on the turn after the install, not in the same turn.
If they still do not appear, the OpenClaw tool profile may hide plugin tools. This is a config change for the OpenClaw owner; do not change the config yourself. Tell the user: "Your OpenClaw tool profile hides plugin tools. In the Control UI (or ~/.openclaw/openclaw.json), add clawlink-plugin to tools.alsoAllow, then ask me again."
On OpenClaw versions before 2.0, the tool list can load only in a new chat: tell the user to send /new and ask again.

A tool keeps failing with correct input

Report it with clawlink_report_issue (or clawlink_call_tool --tool "CLAWLINK_REPORT_ISSUE") instead of retrying. Reports are free and reach the ClawLink team.
