Jev structured decisions via SystemOne, priced by input tokens

+1 more from base.mapleai.shop

Answer typed questions about a state. Demo only, after explicit user confirmation of /SKILL.md terms. No production or consequential real-world decisions. Returns one answer per question: a yes probability (noul), an option and distribution (choice), or a rubric rating (score). Confidence is not proof of correctness. The response reports model and token usage; pay only against the live 402 quote for the request.

Cryptographically verifiable random integer generated from the public drand Quicknet randomness beacon. Choose inclusive min and max values. The response includes the drand round, randomness and signature so the result can be independently checked.

Token monitoring for trading agents: re-checks a token on-chain and reports only what changed since your last call: grade downgrade (A to F), honeypot or sell tax appearing, new risk flags (mint, blacklist, owner powers), price and liquidity moves above your threshold (liquidity pulls, rug signals) and holder concentration shifts, with an alert_level (none, medium, high). Same checks as token-verdict and token-security, computed by us on the blockchain.

Wallet monitoring for agents: watch an EVM address and get only what changed since your last call: native coin and token balance deltas (USDC always included, up to 10 more tokens) and the number of outgoing transactions. Read directly from the blockchain. First call saves a baseline and returns a cursor; pass it on the next call. For treasury and payment tracking, whale and smart-money watching, deposit detection. Chains: base, ethereum, bsc, arbitrum, polygon, avalanche, optimism.

Honeypot and rug check before a trade, built for trading bots that check every token in a loop: up to 5 token addresses per call (Base, Ethereum, BSC, Arbitrum, Polygon, Avalanche, Optimism or Solana), one decision each: ALLOW, CAUTION or BLOCK, with grade A to F, score, honeypot flag and the main reason. Based on our own on-chain checks (contract code, pools, real buy and sell simulation). Results are cached for 10 minutes, so repeat checks answer in milliseconds.

Token safety check: is this token safe to buy? Send a contract address on Base (default), Ethereum, Arbitrum, Optimism, Polygon or Solana; get a rug check and honeypot verdict - LOW_RISK, CAUTION or HIGH_RISK, a 0-100 safety score, one plain-language sentence, can it be sold (simulated sale), buy tax, liquidity, owner control and the top three risks. Rule-based on-chain checks.

Just the network and asset histogram of the live x402 ecosystem: which chains (CAIP-2 ids like eip155:8453 Base, solana:..., and 402index labels) and which payment assets (USDC contract prefixes) the indexed pay-per-call services accept, with counts. Sourced live from 402index.io + Coinbase CDP Bazaar + PayAI Bazaar (source URLs + fetchedAt included).

Portfolio of any wallet in one call with total USD: for an EVM address the native coin and major tokens on Base, Ethereum, BSC, Arbitrum, Polygon, Avalanche and Optimism at once; for a Solana address SOL and every SPL token with a market price; Bitcoin and Tron addresses too. Per asset amount and USD, totals per chain. For agents that check a counterparty, a treasury or their own funds before acting.

Inspect one public MCP HTTP endpoint, auto-detect the stateless 2026-07-28 era or fall back to the legacy initialize lifecycle, then normalize tools/list schemas into a deterministic SHA-256 contract fingerprint. Forest never invokes an advertised tool or attempts authentication. Base mainnet USDC

Return one current Coinbase spot-product snapshot for an exact BASE-QUOTE product id, including venue price, 24-hour price change and provider-reported 24-hour product volume. Forest reads only Coinbase Advanced Trade public market data; it does not infer tickers, infer the provider volume denomination, aggregate venues, read an account or wallet, place orders, provide an executable quote, forecast returns or recommend a trade. Base mainnet USDC

Validate one caller-supplied JSON request or response payload against the documented JSON schema for one exact OpenAPI or Swagger operation. Forest fetches only the supplied public specification, never invokes the described API operation, resolves only bounded local references, and reuses the same deterministic schema subset as json.validate.

Watch a Sui address or SuiNS name in a loop and get only new transactions since your last call, with direction, SUI change, status and link, plus the balance. Pass the returned cursor on the next call.

Sui mainnet in one call: epoch, latest checkpoint, reference gas price, SUI price, total stake and every active validator with staking APY, commission and stake, sorted by APY.

Sui mainnet transaction by digest in plain JSON: status, time, checkpoint, sender, Move calls, gas fee in SUI, balance changes per address with coin symbols, created and changed objects, events.

Everything about a Sui mainnet address or SuiNS name (alice.sui): SUI balance and every other coin with symbol, staked SUI per validator with estimated rewards, USD value, its SuiNS name and latest outgoing transactions.

Watch a Tron address for USDT and USDC (TRC-20) transfers in a loop: each call returns only transfers since your last call with amount, direction, counterparty, time and link, plus the TRX balance. First call covers the last hour (lookback_hours up to 6) and returns a cursor; pass it back next time. For deposit detection and payment confirmation on Tron.

Tron address check: TRX balance and staked TRX, USDT and USDC (TRC-20) balances, USD value, when the account was created and last active, bandwidth and energy, and warning signals (never activated, created in the last 7 days, smart contract instead of a wallet). Use before sending USDT on Tron or to check a counterparty; fresh or never-activated receiving addresses are typical for scams.

Verify an OpenTimestamps proof (.ots as base64, from btc-timestamp or any ots client): upgrades pending proofs from the calendars, checks each Bitcoin attestation against the real block's merkle root and returns status (confirmed, pending), block height and time, the upgraded proof, and whether your text, hash or URL matches.

Timestamp anything on Bitcoin with OpenTimestamps: send text, a SHA-256 hash or a URL and get a standard .ots proof (base64). Only a salted hash leaves our server. The public calendars anchor it in a Bitcoin block within hours; then btc-timestamp-verify returns the block and the complete proof, which anyone can check with the open-source ots tool. For contracts, AI outputs, datasets, invoices and web evidence.
