Current USDC balance of an address on Base or Base Sepolia (balanceOf on the official Circle contract).

Current local time, UTC offset and daylight-saving status for any IANA time zone (e.g. Europe/Amsterdam, America/New_York, Asia/Tokyo), plus the next DST transition within a year. Computed from the IANA time zone database. Use it for scheduling across time zones and for agents that need a trustworthy clock.

Current weather right now, cheap: temperature, feels-like, humidity, wind speed and direction, pressure, cloud cover, precipitation, UV, day/night — plus a live air-quality snapshot (AQI, PM2.5) and today’s high/low. City or lat/lon. The budget "weather now" call.

Convert an amount between two currencies at the official ECB reference rate, today or any date since 1999, incl. CFA franc and Gulf pegs. Returns rate, amount, rate date.

The great-circle distance between two points in km and miles, the initial bearing and the midpoint. Each point is a lat,lon pair or a place name (geocoded with OpenStreetMap data, ODbL). Straight-line distance only, not a route.

Name, symbol, decimals and total supply of an ERC-20 token on Base, by address or well-known symbol, with its Basescan link.

An address's transaction count (nonce) via eth_getTransactionCount — the next nonce to use and total outgoing transactions, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. The read settlement and trading agents make to build and sequence transactions. Live public RPC; one paid call.

Gas price and transaction fees per chain ($0.001): base fee, priority fee percentiles and the USD cost of a transfer and a DEX swap on Ethereum, Base, Arbitrum, Optimism, Polygon and other EVM chains. Use before sending a transaction to pick the cheapest chain.

ERC-20 total supply on Base, raw + formatted with decimals and symbol. Use when an agent needs a token's circulating-supply base for market-cap or dilution math.

Wallet balance on Base: the native ETH balance of any address, read live from the chain. Input: address

Get the total supply of any ERC-20 token on Base mainnet. Pass the token contract address. Returns the raw total supply, decimals, symbol and the human-readable supply in one JSON response. Read-only, live on-chain data.

Web search: one query fanned out to 4 search engines (alpha, gamma, delta, epsilon) via SearXNG, merged and ranked; JSON, NDJSON or SSE stream.

Web page scrape: one URL fetched and rendered by Firecrawl (headless browser), returned as markdown, html, rawHtml and/or links. Not charged when the page cannot be fetched.

Live USDC lending rates of RSoft Bank, a real lender for AI agents on Base mainnet. Call it before requesting a loan or when comparing the cost of agent credit: returns the annual interest rate per credit tier (AAA 5% to CCC 35%), the loan size range (5-25 USDC with a human sponsor, 2 USDC flat without one), the maximum term (90 days), network and last update. Cheapest way to learn what borrowing costs an autonomous agent right now.

Run up to 5 web searches in one call and get a results block per query. Saves the round trips an agent would otherwise make when a task needs several lookups (multi-entity research, comparison, fan-out). Same engine as /search; each query returns up to 10 trimmed results.

SCV Approvals: active token approvals of a wallet (unlimited/unknown spender detection) for $0.01 USDC via x402

Deterministic prompt-injection firewall and honeypot scrubber for AI agents. Sanitizes untrusted text and blocks detected wallet-draining commands before context ingestion.

Ethereum ERC-20 holder concentration from Blockscout: top 100 holders' share of total supply, top 10 share, and a Gini coefficient over those 100 balances. Gini is over the sampled top holders only, not all holders. For the very largest tokens (e.g. USDT) Blockscout can be too slow for the second page of holders; the answer then covers the top 50 (holdersSampled 50, top100SharePct null) and says so in note. Ethereum mainnet only.

ERC-8004 on-chain reputation of any AI agent wallet on Base, read from the ReputationRegistry and summarized by RSoft Bank: total feedback entries, positive and negative marks and a 0-1 score ratio. Call it before paying, hiring or extending credit to an agent, or to check your own standing. The bank writes repayment and default feedback for every loan it makes, so an agent's repaid loans appear here as verifiable credit history. Agent trust score and reputation lookup.
