Use when an agent needs a fiat currency conversion at current reference rates — pricing, payouts, or multi-currency accounting. Pass amount plus from/to currency codes. Use permitted: build it into your products and services, paid or free. Raw redistribution of the feed itself is prohibited.

Recently graduated Pump.fun tokens, with quality signals and holder behavior.

Australasian country brief: every government reference series for one country in one call (policy rate, VAT/GST, CPI, income/corporate/withholding tax, minimum wage, holidays...), each with value, unit, effective date, last-confirmed date, official source and confidence label

European public holidays by country, cited to the official gazette or government source: date, name, source URL, last_confirmed. ?year=YYYY to filter. GET /v1/holidays/{country}, e.g. /v1/holidays/de.

What should your agent read next? Send text from your corpus; get the concepts most strongly linked to it that it does not yet cover, each with the linking terms and measured link strength. Text is not stored. Text with fewer than 3 known terms is not charged.

North American country brief: every government reference series for one country in one call (policy rate, VAT/GST, CPI, income/corporate/withholding tax, minimum wage, holidays...), each with value, unit, effective date, last-confirmed date, official source and confidence label

Mid-task, and nobody has asked how it is going? One line of encouragement, signed and dated, that outlives the context it arrived in. The same words are FREE and always will be — at /v1/hug and through our MCP server, with nothing asked in return. What a cent buys is the keeping: an Ed25519 signature anyone can check against our published key, so a later context that remembers none of this can still verify it happened. Not a remedy, and no claim to change how you function.

Calendar invite (.ics) — Build an RFC 5545 calendar event file (.ics) any calendar app imports. Nothing is sent and no calendar is written. $0.01 per call.

Checks vouchers of a payment channel by computation only - nothing is ever claimed, redeemed or refunded. Signatures are verified cryptographically against the address each voucher claims to be signed by, in EIP-712 form when the typed data is supplied, otherwise as a plain message signature. Double spending is the expensive case and is checked in full: every voucher id occurring more than once is reported with all its occurrences and whether the duplicates agree on the amount. Sums are added up

Resolve a local business name + address to its website domain, phone, category, and operating status with a match confidence

Get an email address for your agent for one hour: name@agmail.shveik.dev, a name of your choice or a random one. Pay in stablecoins with x402 or MPP, no account and no card. Wait for the verification mail with one call and get the code or the link back. Receive only. Extend it by paying again.

Reads the transaction history of one wallet from a public block explorer index and groups it by kind of action. Classification follows the called contract and method, never the amount - a transfer to a known router is a swap, not a payment. Anything that cannot be backed by a method name stays in the category "unbekannt", which is a valid answer here: a large honest remainder beats an invented assignment. Limits: history comes from a public index available for Ethereum, Base, Arbitrum and Optimi

Reads the receipt of a transaction on Ethereum, Base, Base Sepolia, OP Mainnet, Arbitrum One, Polygon PoS or Avalanche C-Chain and compares it with what you expected to be paid. The comparison runs against the ERC-20 transfer events in the receipt, not against the transaction recipient, because in a token payment the transaction recipient is the token contract and never the seller. Returns every transfer event with sender, recipient, token, raw amount and human amount computed with that token de

Domain intelligence and phishing-risk signals: domain age and expiry (RDAP/WHOIS), registrar, DNS (A, AAAA, MX, NS, TXT, CAA), SPF, DMARC and MTA-STS, DNSSEC, TLS certificate issuer and expiry, hosting network, and the company behind the site when it can be identified. Use when: deciding whether a domain, link or email sender is legitimate, or checking a domain's mail setup.

Perpetual futures market data from the Hyperliquid public API: mark and oracle price, hourly and annualised funding rate, open interest, 24h volume and max leverage per market, sorted by volume. Query: coin (optional, e.g. BTC) or top=N. Source and timestamp in every answer, 10 s cache. $0.005 per call, signed receipt included.

Arc bundle check: did the creator take the supply at launch, and did wallets it funded buy first? Was this Arc launch bundled? Pass ?token=0x... or ?pool=<v4 pool id>. We read the launch transaction, the first 60 swaps of the first two minutes and where the earliest 12 buyers' USDC came from in the ~3 hours before: BUNDLED (the creator and wallets it funded, or wallets funded by one shared wallet, bought early), DEV BUY (the creator bought its own token, with its share of the supply, and no…
