Every agent-payable API.

One two-sentence horror story, in English or Spanish, by theme: domestic, technological, cosmic or folk. Returned SPLIT into setup and payoff as well as joined, so a narrating agent can deliver the first line, pause, and then land the second. Takes parameters, returns an id to avoid repeats, and accepts a seed for a reproducible answer.

Look up a transaction by hash on base, ethereum, arbitrum, optimism, polygon, bsc: status (success/reverted/pending), block and timestamp, from/to, value, gas used, fee in native coin and USD, method selector, created contract, and decoded ERC-20 transfers with token symbols and amounts. Transaction and receipt in one call.

Plain-English explanation of any transaction on Base, Ethereum, Arbitrum or Optimism: what happened, who sent what to whom (decoded token transfers with amounts and symbols), the method called, fee paid, and success/failure. Returns a summary plus the structured facts it is based on.

Normalized transactions for an address on a chain (Alchemy Transfers API). x402-paid, USDC on Base.

Status of a transaction on Base, Ethereum, Arbitrum or Optimism: pending/success/failed, block, confirmations, from/to, gas used, log count. Deterministic, no LLM.

On-chain transaction receipt for any Base tx (?tx=0x...): status, block, gas used, from/to, logs count — agents verify their own settlements and counterparty claims

Transaction receipt status/block/confirmations on Base or Ethereum via eth_getTransactionReceipt. Validates 0x hash BEFORE settle.

Explain and preflight an unsigned Base transaction, EIP-712 typed data, or an EIP-3009 x402 payment authorization before you sign it. Decodes intent against verified ABIs, resolves proxies, classifies approvals, and checks a payment authorization against the quote it claims to pay: recipient, amount, asset, chain, freshness, and nonce replay. Returns unknown rather than guessing when a selector is ambiguous. Not a guarantee that a transaction is safe or profitable.

One pre-sign safety verdict (GREEN, REVIEW or BLOCK) fusing transaction, signature, address, URL and token checks for AI wallet agents.

Simulate an EVM transaction before signing. Decodes the calldata into a named function with arguments and security risk flags, AND runs a keyless static eth_call preview to tell you whether the transaction would succeed or revert (with the decoded revert reason). Use it to catch a failing or malicious transaction before you broadcast it. Read-only, no keys, no node infra. Asset-level change tracing is v2.

Decode raw EVM calldata into a named function, signature and arguments, plus security risk flags (unlimited token approval, setApprovalForAll, ownership transfer, unknown selector, native value transfer). Keyless, deterministic, no simulation - the cheap way for an agent to understand and risk-screen a piece of calldata before signing.

Ask a typed question about any content and get an answer your code can branch on, not prose to parse. Three question types: choice (pick one of your named options, with a probability for each and a confidence), score (a position on levels you describe), and noul (a yes/no as a probability from 0 to 1). Up to 8 questions per call, answered in parallel over one piece of state. Model-backed, not deterministic.

Ranks edit-distance proximity between a candidate name and supplied popular package names. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.

Generates the typical misspellings of a package name and looks up every one of them in the registry. Generation rather than search is deliberate: most of the seven ecosystems have no search API, and the ones that do rank by popularity instead of similarity, so a fresh squat with no downloads never appears.

Call when an agent needs the UTC offset of an IANA time zone on a date, including daylight saving. Not a live clock.

Use when an agent must track new U.S. rules, proposed rules, agency notices and fresh SEC disclosures. Input: optional q (topic), agency (Federal Register slug), doc_type, form (8-K, 13F-HR, NPORT-P...), source, days, limit. Output: JSON Federal Register documents (type, agencies, abstract, effective/comment dates, CFR, links) and latest SEC filings by companies/funds (form, filer, CIK, filed, link). Metadata only. Example: ?q=stablecoin&days=30

Matches vendor, fund, company, or account names across two datasets using normalized and conservative fuzzy matching.

Flags exact and normalized duplicate invoices using invoice number, vendor, amount, and date fields with source indexes.

Compare any two portfolio or SEC-style holdings datasets (up to 1000 rows each) by CUSIP, ticker, ISIN, or internal identifier. Return opened, closed, increased, decreased, and field-level changed positions with totals and weight changes.

Deterministic portfolio performance attribution vs BTC, ETH, stETH or any benchmark. Returns Modified Dietz and money-weighted (XIRR) returns, per-position contribution and alpha, per-input source status and per-position data status with the reason, and a hashed (optionally EIP-191 signed) record of the calculation. No LLM.

Reconciles invoice, purchase-order, or ledger records and returns traceable missing, extra, and changed fields.

Token holder-value check: holder revenue yield vs emissions dilution, net real yield, and an annualized unlock-dilution stress scenario over the next 90 days. Also P/holder-revenue, P/fees, FDV and unlock schedules. Deterministic; caller-asserted data status with reason for every top-level calculated figure; hashed and optionally signed. No LLM.
