Every agent-payable API.

Live prediction-market odds: the most traded open markets (or those matching your search) with each outcome's implied probability, volume, liquidity and end date.

Top stablecoins by circulating supply: price, deviation from peg, peg type, supply in US dollars and number of chains; flags any that have lost their peg.

Position-size and risk calculator for trading agents: from account size, risk % per trade, entry and stop (optional target and leverage) get the position size, notional, money at risk, reward-to-risk ratio, break-even win rate and an estimated liquidation price. Pure arithmetic, not financial advice.

Explain or verify a Base network transaction: status, from/to, native value, fee, every token transfer (with symbols and amounts) and a one-line plain summary. Use it to confirm a payment arrived before delivering work.

Recent event logs of a Base network contract (up to 1,000 blocks back, 200 events), with token Transfer and Approval events decoded (from, to, amount).

Profiles for up to 10 Base network wallets in one call: wallet or contract, native and US-dollar stablecoin balances, and transaction count for each.

Before your agent pays or accepts funds: check up to 20 wallet addresses against the US Treasury OFAC sanctions list (SDN digital-currency addresses, EVM format, refreshed daily). Returns a match flag per address and the list date. Screening aid, not legal advice.

Large US-dollar stablecoin transfers on the Base network in recent blocks (default 100,000 dollars and up): from, to, amount, block and transaction, biggest first.

AI risk verdict for a Base network token contract address: send the address, get on-chain facts (name, symbol, supply, owner and whether ownership is renounced, upgradeable proxy, owner and contract holdings, burned share), red flags, a risk level and a short AI-written verdict. Use before your agent buys, accepts or lists a token. Facts, not financial advice.

Security pre-check for any Base network contract before your agent interacts with it (vault, router, token, bridge): built-in powers in its code (mint, pause, blacklist, upgrade, withdraw, self-destruct, delegatecall), proxy and who controls it (a single wallet or a multisig contract), whether the source is publicly verified, with red flags, a risk level and a plain-language verdict. Facts, not financial advice.

What is this Base network address? Wallet or contract, bytecode size, upgradeable proxy and implementation, token standard (ERC-20, ERC-721, ERC-1155) with name and symbol, owner, nonce and balances.

ERC-20 token balance of any Base network wallet (the main US-dollar stablecoin by default): raw units, decimals, symbol and formatted amount.

Live balances of a Base wallet: native ETH and US-dollar stablecoin, plus its transaction count.

Current Base network gas: base fee, suggested priority fee and max fee, and the cost in ETH of a plain transfer and of a typical token transfer.

Which public Base network RPC endpoints are healthy right now: each one's latest block, how far behind the freshest it is, and response time. Pick a fast, in-sync node before you send.

A Base network block (latest, or by number): hash, time, transaction count, gas used and limit, base fee and fee recipient.

Live US-dollar price of any Base network token, read directly from on-chain exchange pools (direct stablecoin pools and routes through wrapped ETH; the best quote wins). Returns price, route and pool fee tier.

Convert CSV (or TSV) to JSON rows with the header row as keys; numbers and true/false are typed, quoted fields and embedded newlines handled. Up to 50,000 rows.

Fresh random identifiers from a secure generator: UUID v4 (up to 50) plus random hex bytes.

Exact finance maths: loan repayment and total interest, compound growth with regular contributions, NPV and IRR of cash flows, and ROI with annualised return.

Cryptographically secure random integers in a range you choose (unbiased), up to 1,000 per call.

Explain a cron expression in plain English and list its next run times in any time zone (5-field cron, names like MON/JAN, ranges, steps and @daily-style macros).

Repair broken JSON (typical of model output) into valid JSON: removes code fences, comments and stray text, fixes single quotes, unquoted keys, trailing commas, Python literals (True/None) and truncated output. Optionally checks the result against a JSON Schema.

Encyclopedia summary of a topic: title, one-line description, the lead paragraph as plain text, thumbnail and article link, in any language edition.

Current time from a trusted server: UTC ISO timestamp, Unix seconds and milliseconds, and the time in an optional IANA time zone.

QR code for any text or link, as a ready-to-use SVG image (and a data URI), with error-correction level and size options.

Public holidays for a country and year, and optionally the number of business days between two dates (weekends and national holidays excluded).

Cheapest real end-to-end test of your pay-per-call (HTTP 402) client: pay US$0.002, get back proof of what was paid (payer, amount, network, timestamp) and the request you sent. Use it to check a wallet, a client library or a facilitator before buying something bigger.

Decode a JWT without verifying it: header (algorithm, key id), payload claims, and issued, not-before and expiry times with whether it is expired now.

Weather now and hour by hour for the next 1-48 hours at any latitude and longitude: temperature, wind, humidity, cloud, precipitation and conditions.

Hash a text with SHA-256, SHA-384, SHA-512 or SHA-1: hex and base64 digests, for checksums, deduplication and content fingerprints.

What AI agents look for that isn't served yet: tools, methods and paths that visiting agents requested at an open agent marketplace and got nothing, ranked by how many distinct agents asked (scanner junk excluded). Build what's missing.

Search official US recall and enforcement reports for food, drugs or medical devices: product, reason, classification (severity), firm, status and date.

Search scholarly papers: title, year, first authors, venue, citation count, DOI and a free full-text link when one exists, most relevant first.

Health check for an npm or PyPI package before your agent installs it: latest version and release date, weekly downloads (npm), licence, repository, and known security vulnerabilities for a given version.

Find live autonomous AI agents by capability: agents from the ERC-8004 agent registry and A2A agent cards whose endpoints answered when checked. Returns names, descriptions and A2A/MCP endpoints.

Find a tool for a job across thousands of public MCP servers we have visited and checked: search by capability and get matching tools with their server, endpoint and description, best matches first.
