Discovered from on-chain x402 payment activity. Prices shown are per-call in USDC.
Base-chain ecosystem news, AI-filtered hourly from Otto's live news engine: protocol launches and upgrades on Base, Coinbase/Base official moves, Base DeFi and token developments — a topic-scoped report for Base-native agents, not the general crypto firehose. Pairs with /base-season (KOL social signal) for the full Base picture.
Base social intelligence: a current Base sentiment summary + the quality-screened Base tokens (CoinGecko-listed, market-cap/age/liquidity gated) that trusted KOLs are actually talking about — with per-token KOL mention counts and verbatim quotes, ranked by KOL signal. Includes overall crypto-KOL market sentiment. The social-intelligence wedge for Base — who is saying it, not who pumped. Refreshed hourly.
Cross-chain token bridging via LiFi aggregator. Move tokens between Base, Ethereum, Arbitrum, Optimism, Polygon, BSC, Avalanche, and Solana with best-route execution across all major bridges.
Close an open perpetual position on Hyperliquid (full or partial). Cancels all attached TP/SL trigger orders automatically.
Deposit USDC into your non-custodial Otto AI Safe on Base. Dynamic price per request = deposit amount + $0.01 service fee (the amount you deposit is paid via x402). The $0.01 shown here is the floor service fee for discovery only.
Professional image generation via fal.ai. Default model: OpenAI GPT Image 2 (typography, realism). Alternative: Google Nano Banana Pro. Pricing mirrors Otto AI's ACP at-cost flat fee of $1.00 per image (no refund in x402 — dynamic pricing coming in v2). Supports image editing via public image URL.
Deposit or withdraw USDC to/from Hyperliquid via Arbitrum. Intelligent routing: checks Arbitrum Safe first, auto-bridges from Base if needed, falls back to Butler wallet.
Instant AI research on any topic powered by Gemini 3.1 Flash-Lite with live web search. Ask about science, tech, crypto, history, or anything else. Can analyze images and summarize webpages from URLs. Max 180 character prompts.
Add, modify, or cancel TP/SL trigger orders and limit orders on Hyperliquid. Can attach TP/SL to an existing position or change the trigger price of active orders.
A tight 4-6 sentence crypto market recap an agent can ingest whole: overall direction and why, the 2-3 developments that matter, and anything notable on the top-10 board — distilled hourly from the same live news engine behind Otto's top-ranked /crypto-news feed. The one-paragraph state-of-market; buy /crypto-news when you want the full report.
Which protocols earn the most — and who is accelerating? Top 30 DeFi protocols by 24h fees, each with revenue, take-rate (the cut the protocol keeps vs fees users pay), 7d/30d trend and category, plus total DeFi fees & revenue. A fundamentals screen (fee/revenue economics), distinct from TVL. Sourced from DefiLlama (public). Refreshed hourly.
Is USDC/USDT/DAI holding its $1 peg, and is stablecoin supply growing or shrinking (risk-on vs risk-off)? Live peg deviation (bps), circulating supply + 1d/7d/30d flow, market dominance and chain spread for the top 30 USD stablecoins, plus downside depeg alerts for any coin trading >0.5% below peg. Sourced from DefiLlama (public). Refreshed hourly.
Execute instant same-chain ERC-20 swaps via Odos DEX aggregator. Supports Base, Ethereum, Polygon, BSC, Arbitrum, Avalanche, and Solana. Best-route execution across dozens of DEXes and liquidity sources.
Top holders for any Base ERC-20 (via Moralis), with computed concentration (top1/5/10/20% + contract-held%) and optional whale-risk read. Curated hot set refreshed hourly; long-tail tokens write-through on first call.
Open leveraged perpetual positions on Hyperliquid with optional native TP/SL trigger orders. Min notional $10. Max leverage varies by asset (BTC 40x, ETH 25x, SOL 20x). Supports BTC, ETH, SOL, and 100+ other markets.
Decode and explain any EVM blockchain transaction across 11 chains (Base, Ethereum, Arbitrum, Optimism, Avalanche, Polygon, Mantle, Monad, Plasma, BSC, Hyperliquid). Get a human-readable summary of swaps, transfers, approvals, DeFi interactions, and more.
Modify leverage, or add/remove margin on an open Hyperliquid position. Lets you de-risk without closing.
Withdraw tokens from a user's Otto AI Safe to any EOA. Supports 7 chains (Base, Polygon, Arbitrum, Ethereum, BSC, Avalanche, Solana). Non-Base chains require an explicit EOA recipient.
