🚀Put Your $TMAI to Work: Daily Rewards, No Locks, Up To 200% APR.

Token Metrics Team
5 min

Liquidity farming just got a major upgrade. Token Metrics AI ($TMAI) has launched its first liquidity incentive campaign on Merk — and it’s designed for yield hunters looking to earn fast, with no lockups, no gimmicks, and real rewards from Day 1.

đź“… Campaign Details

  • Duration: June 5 – June 19, 2025
  • Rewards Begin: 17:00 UTC / 1:00 PM ET
  • Total TMAI Committed: 38 million+ $TMAI
  • No Lockups: Enter or exit at any time
  • APR Potential: Up to 200%

For two weeks, liquidity providers can earn high daily rewards across three different pools. All rewards are paid in $TMAI and distributed continuously — block by block — through the Merkl platform.

💧 Where to Earn – The Pools (as of June 5, 17:00 UTC)

Pool                                                    Starting APR %               Total Rewards (14 days)                Current TVL

Aerodrome WETH–TMAI        150%                                16.79M TMAI (~$11,000)                   $86,400

Uniswap v3 USDC–TMAI        200%                                14.92M TMAI (~$9,800)                    $19,900

Balancer 95/5 WETH–TMAI    200%                                5.60M TMAI (~$3,700)                       $9,500

These pools are live and actively paying rewards. APR rates aren’t displayed on Merkl until the first 24 hours of data are available — but early providers will already be earning.

đź§  Why This Campaign Stands Out

1. Turbo Rewards for a Short Time

This isn’t a slow-drip farm. The TMAI Merkl campaign is designed to reward action-takers. For the first few days, yields are especially high — thanks to low TVL and full daily reward distribution.

2. No Lockups or Waiting Periods

You can provide liquidity and withdraw it anytime — even the same day. There are no lockups, no vesting, and no delayed payout mechanics. All rewards accrue automatically and are claimable through Merkl.

3. Choose Your Risk Profile

You get to pick your exposure.

  • Want ETH upside? Stake in Aerodrome or Balancer.
  • Prefer stablecoin stability? Go with the Uniswap v3 USDC–TMAI pool.

4. Influence the Future of TMAI Yield Farming

This campaign isn’t just about yield — it’s a test. If enough users participate and volume grows, the Token Metrics Treasury will consider extending liquidity rewards into Q3 and beyond. That means more TMAI emissions, longer timelines, and consistent passive income opportunities for LPs.

5. Built for Transparency and Speed

Rewards are distributed via Merkl by Angle Labs, a transparent, gas-efficient platform for programmable liquidity mining. You can see the exact rewards, TVL, wallet counts, and pool analytics at any time.

đź”§ How to Get Started

Getting started is simple. You only need a crypto wallet, some $TMAI, and a matching asset (either WETH or USDC, depending on the pool).

Step-by-step:

  1. Pick a pool:
    Choose from Aerodrome, Uniswap v3, or Balancer depending on your risk appetite and asset preference.

  2. Provide liquidity:
    Head to the Merkl link for your pool, deposit both assets, and your position is live immediately.

  3. Track your earnings:
    Watch TMAI accumulate daily in your Merkl dashboard. You can claim rewards at any time.

  4. Withdraw when you want:
    Since there are no lockups, you can remove your liquidity whenever you choose — rewards stop the moment liquidity is pulled.

🎯 Final Thoughts

This is a rare opportunity to earn serious rewards in a short amount of time. Whether you’re new to liquidity mining or a DeFi veteran, the TMAI Merkl campaign is built for speed, flexibility, and transparency.

You’re still early. The best yields happen in the first days, before TVL rises and APR stabilizes. Dive in now and maximize your returns while the turbo phase is still on.

Token Metrics API Joins RapidAPI: The Fastest Way to Add AI-Grade Crypto Data to Your App

Token Metrics Team
5 min

The hunt for a dependable Crypto API normally ends in a graveyard of half-maintained GitHub repos, flaky RPC endpoints, and expensive enterprise feeds that hide the true cost behind a sales call. Developers waste days wiring those sources together, only to learn that one fails during a market spike or that data schemas never quite align. The result? Bots mis-fire, dashboards drift out of sync, and growth stalls while engineers chase yet another “price feed.”

That headache stops today. Token Metrics API, the same engine that powers more than 70 000 users on the Token Metrics analytics platform, is now live on RapidAPI—the largest marketplace of public APIs with more than four million developers. One search, one click, and you get an AI-grade Crypto API with institutional reliability and a 99.99 % uptime SLA.

Why RapidAPI + Token Metrics API Matters

  • Native developer workflow – No separate billing portal, OAuth flow, or SDK hunt. Click “Subscribe,” pick the Free plan, and RapidAPI instantly generates a key.

  • Single playground – Run test calls in-browser and copy snippets in cURL, Python, Node, Go, or Rust without leaving the listing.

  • Auto-scale billing – When usage grows, RapidAPI handles metering and invoices. You focus on product, not procurement.

What Makes the Token Metrics Crypto API Different?

  1. Twenty-one production endpoints
    ‍
    Live & historical prices, hourly and daily OHLCV, proprietary Trader & Investor Grades, on-chain and social sentiment, AI-curated sector indices, plus deep-dive AI reports that summarise fundamentals, code health, and tokenomics.

  2. AI signals that win
    ‍
    Over the last 24 months, more than 70 % of our bull/bear signals outperformed simple buy-and-hold. The API delivers that same alpha in flat JSON.

  3. Institutional reliability
    ‍
    99.99 % uptime, public status page, and automatic caching for hot endpoints keep latency low even on volatile days.

Three-Step Quick Start

  1. Search “Token Metrics API” on RapidAPI and click Subscribe.
  2. Select the Free plan (5 000 calls / month, 20 request / min) and copy your key.
  3. Test:

bash

CopyEdit

curl -H "X-RapidAPI-Key: YOUR_KEY" \

     -H "X-RapidAPI-Host: tokenmetrics.p.rapidapi.com" \

     https://tokenmetrics.p.rapidapi.com/v2/trader-grades?symbol=BTC

The response returns Bitcoin’s live Trader Grade (0-100) and bull/bear flag. Swap BTC for any asset or explore /indices, /sentiment, and /ai-reports.

Crypto MCP Server: Token Metrics Brings One-Key Data to OpenAI, Claude, Cursor & Windsurf

Token Metrics Team
5 min

The modern crypto stack is a jungle of AI agents: IDE copilots that finish code, desktop assistants that summarise white-papers, CLI tools that back-test strategies, and slide generators that turn metrics into pitch decks. Each tool speaks a different protocol, so developers juggle multiple keys and mismatched JSON every time they query a Crypto API. That fragmentation slows innovation and creates silent data drift.

To fix it, we built the Token Metrics Crypto MCP Server—a lightweight gateway that unifies every tool around a single Multi-Client Crypto API. MCP (Multi-Client Protocol) sits in front of the Token Metrics API and translates requests into one canonical schema. Paste your key once, and a growing suite of clients speaks the same crypto language:

  • OpenAI Agents SDK – build ChatGPT-style agents with live grades
  • Claude Desktop – natural-language research powered by real-time metrics
  • Cursor / Windsurf IDE – in-editor instant queries
  • Raycast, Tome, VS Code, Cline and more

Why a Crypto MCP Server Beats Separate APIs

Consistency – Claude’s grade equals Windsurf’s grade.
One-time auth – store one key; clients handle headers automatically.
Faster prototyping – build in Cursor, test in Windsurf, present in Tome without rewriting queries.
Lower cost – shared quota plus $TMAI discount across all tools.

Getting Started

  1. Sign up for the Free plan (5 000 calls/month) and get your key: https://app.tokenmetrics.com/en/api
  2. Click the client you want to setup mcp for: smithery.ai/server/@token-metrics/mcp or https://modelcontextprotocol.io/clients

Your LLM assistant, IDE, CLI, and slide deck now share a single, reliable crypto brain. Copy your key, point to MCP, and start building the next generation of autonomous finance.

How Teams Use the Multi-Client Crypto API

  • Research to Execution – Analysts ask Claude for “Top 5 DeFi tokens with improving Trader Grades.” Cursor fetches code snippets; Windsurf trades the shortlist—all on identical data.
  • DevRel Demos – Share a single GitHub repo with instructions for Cursor, VS Code, and CLI; workshop attendees choose their favorite environment and still hit the same endpoints.
  • Compliance Dashboards – Tome auto-refreshes index allocations every morning, ensuring slide decks stay current without manual updates

Pricing, Rate Limits, and $TMAI

The Crypto MCP Server follows the core Token Metrics API plans: Free, Advanced, Premium, and VIP up to 500 000 calls/month and 600 req/min. Paying or staking $TMAI applies the familiar 10 % pay-in bonus plus up to 25 % staking rebate—35 % total savings. No new SKU, no hidden fee.

Build Once, Query Everywhere

The Token Metrics Crypto MCP Server turns seven scattered tools into one cohesive development environment. Your LLM assistant, IDE, CLI, and slideshow app now read from the same real-time ledger. Copy your key, point to MCP, and start building the next generation of autonomous finance.
