19 tools

• get_syx_value

  Get the current Stablecoin Yield Index (SYX) value and rolling averages (7-day, 30-day, 90-day). SYX is a TVL-weighted benchmark for conservative USDC yield, calculated directly from canonical onchain contracts on Ethereum, Base, and Arbitrum — not aggregated from third-party…

• get_syx_methodology

  Get the full SYX methodology — how the index is constructed, which onchain components are included, how weights are calculated, the measurement windows, and the exclusion rules. Use this when the user asks "how is SYX calculated" or "what does SYX measure" or "what protocols…

• get_syx_components

  List the current SYX components with their live weights, APYs, and total value locked. SYX is composed of 8 onchain USDC supply markets: Aave v3 (Ethereum, Base, Arbitrum), Compound v3 (Ethereum), and Morpho v2 Prime USDC vaults from Steakhouse Financial and Gauntlet (Ethereum…

• get_syx_history

  Get historical SYX index readings. Use this when the user asks how SYX has moved over time, wants a chart of recent readings, or wants to compare current SYX to its recent trend. Returns time-series data points.

• list_vaults

  List all stablecoin yield vaults available on ACCRUE with their current live APYs, risk tiers, chains, and underlying protocols. Returns spot, 7-day realized, and 30-day realized APYs for each vault. Use this when the user asks "what vaults are available", "what strategies does…

• get_vault_details

  Get full details on a single ACCRUE yield vault by ID or name. Returns the live spot APY, 7-day realized APY, 30-day realized APY, TVL, chain, risk tier, underlying protocol, and metadata. Use this when the user asks about a specific vault like "tell me about Steakhouse Prime on…

• compare_vaults

  Compare two or more ACCRUE vaults side by side. Returns each vault's live APYs, TVL, chain, and risk tier, plus a comparison summary highlighting the highest yield, highest TVL, and whether the vaults share a risk tier. Use this for "compare X and Y" or "is Aave or Compound…

• search_vaults

  Filter ACCRUE vaults by chain, risk tier, protocol, and/or minimum APY. Returns the matching vaults with live APY data. Use this when the user wants to narrow down by criteria like "Base vaults only", "highest yield on Arbitrum", or "show me conservative options above 4%".

• list_model_portfolios

  List all model portfolios on ACCRUE, organised per chain. Each portfolio is a pre-built blend of underlying vaults sized to a risk profile. Returns each portfolio with its live blended APY computed from underlying vault yields. Use this when the user asks "what portfolios are…

• get_portfolio_details

  Get full details on a single model portfolio: its underlying vault allocations, the live APY of each underlying vault, and the blended portfolio APY. Use this when the user asks about a specific portfolio like "what is in Core on Ethereum" or "how does Foundation on Base work".

• recommend_strategy

  Recommend a vault or model portfolio for a user based on their risk profile and chain preference. Uses live APY data to choose the best current option. Returns a recommendation with reasoning. Use this when the user describes what they want ("I want safe yield on Base"…

• calculate_yield

  Project compound returns for a USDC deposit into any ACCRUE vault or model portfolio over a given holding period. Uses live APY data and applies the ACCRUE platform fee, which is charged on PRINCIPAL (0.25%/yr standalone, 0.50%/yr managed falling to 0.25% above $1M) and never on…

• get_platform_info

  Get high-level facts about the ACCRUE platform: fee structure, custody model, supported chains, wallets, KYC requirements, withdrawal terms, and AI agent integration status. Use this when the user asks "what is ACCRUE", "how does ACCRUE work", "what are the fees", or anything…

• search

  Natural-language search across all ACCRUE vaults and portfolios. Use this for vague queries like "find me high-yield options", "show me lending strategies on Base", or "what aggressive options are there". Returns matching vaults and portfolios with live data.

• list_vault_contracts

  List the ACCRUE vault and model-portfolio CONTRACTS an agent can deposit into on one chain, read live from the ACCRUE Registry (registry.approvedVaults()). Returns address, on-chain symbol and name, whether it is a portfolio, the minimum deposit, and — if you pass your account…

• prepare_transaction

  Prepare a deposit into or withdrawal from an ACCRUE vault for the calling agent's own wallet. Nothing is signed or sent. Returns (1) eth_path: ordinary unsigned transactions to send in order from the account, paying gas in ETH — ALWAYS returned; and (2) usdc_path: when…

• build_user_operation

  Second step of the USDC-gas path. Pass back the draft from prepare_transaction unchanged. For usdc_path, add permit_signature (EIP-712 signature of the returned permit). For either path, add authorization_signature (EIP-7702) if prepare asked for one. Returns the final user…

• submit_user_operation

  Final step of the USDC-gas path. Pass user_operation from build_user_operation and your signature over its typed data (or hash). ACCRUE checks that the operation is an ACCRUE deposit or withdrawal for this account, paid through Circle's paymaster in USDC, and that you signed it…

• get_transaction_status

  Status of a submitted operation: pending, success or reverted, the transaction hash and explorer link, and what the account paid for the network fee (the exact USDC Circle charged).
