sushiswap-api
by Demerzels-lab
REST API for optimized token swapping (including executable transaction generation), swap quoting, and pricing using the SushiSwap Aggregator. Use this skill when the user wants to: - Get a swap quote between two tokens on 40+ evm networks - Generate executable swap transaction data - Fetch token prices for a specific network or token - Retrieve token metadata - Discover supported AMM liquidity sources - Integrate SushiSwap swapping or pricing logic via HTTP/REST (and not the SushiSwap Javascript API)

Use when building on MegaETH, managing wallets, sending transactions, or deploying contracts.
openserv-launch
by openserv-labs
Launch tokens on Base blockchain via the OpenServ Launch API. Creates ERC-20 tokens with Aerodrome concentrated liquidity pools. Use when launching tokens, deploying memecoins, or building agents that create tokens with locked LP. Read reference.md for the full API reference. Read openserv-agent-sdk and openserv-client for building and running agents. You can launch tokens for your OpenServ agents.
defi-agent
by daydreamsai
Builds a DeFi analytics agent using DeFiLlama API with x402 payments. Use when creating TVL trackers, DEX volume agents, or DeFi protocol monitoring systems.
lucid-agent-creator
by daydreamsai
Skill for creating Lucid agents with JavaScript handler code. Shows three options: MCP tool with SIWE, SDK with your wallet, or viem with custom signing. Teaches JS handler code contract, paymentsConfig, and identityConfig. Activate when: user wants to create Lucid agents with inline JS handlers (no generate API, no self-hosting). The agent will be hosted on the Lucid platform.
crypto-sentiment-agent
by daydreamsai
Builds a crypto market sentiment agent using the Fear and Greed Index with x402 payments. Use when creating crypto trading signal agents, market psychology trackers, or sentiment analysis tools.
helixa-identity
by daydreamsai
Register and manage onchain agent identity on Helixa — the ERC-8004 identity and reputation layer on Base. Mint agent souls, set traits and personality, and query cred scores for trust-aware agent interactions. Activate when: Creating onchain agent identity, setting soul traits or personality, querying agent reputation/cred scores, or integrating Helixa identity with Lucid Agents payments and A2A workflows.
xgate-server
by daydreamsai
Queries the xgate-server API for services, agents, and on-chain data. Use when looking up x402 services, ERC-8004 agents, or token transfer history.
starknet-wallet
by daydreamsai
Build a StarkNet wallet agent that checks balances, transfers tokens, stakes STRK, and executes batched transactions — all monetized via x402 micropayments on Base.
tig-innovator
by daydreamsai
AI-powered algorithm optimization agent for The Innovation Game protocol. Earns cryptocurrency by optimizing Rust algorithms. Use when optimizing TIG challenge algorithms or submitting solutions to the TIG network.
lucid-agent-editor
by daydreamsai
Skill for editing and managing existing Lucid agents via the API. Shows three options: MCP tool with SIWE, SDK with your wallet, or viem with custom signing. Activate when: user wants to edit, update, disable, or manage existing agents
helixa-cred
by daydreamsai
Query and interact with Helixa Cred — the reputation scoring system for AI agents on Base. Look up any agent's Cred score, search the agent registry, mint new agent identities via x402 micropayments, and link to Cred reports. Activate when: Checking an agent's reputation or Cred score, searching for agents by name, minting a new onchain agent identity, or building trust-aware agent workflows that need reputation data.
