What the options market expects price to do, not what leverage is doing: the 30-day implied volatility index for BTC and ETH, with its percentile over the last month and the expected move in percent over 1, 7 and 30 days. Funding tells you who is crowded; this tells you how much movement is already priced in — and whether hedging is cheap or expensive relative to where it has been.

Read the messages received by a phone number rented through /v1/sms/number: sender, body, and reception time, returned as structured data so an agent can extract a verification code without human help. The number is a physical SIM in a handset we operate, so it receives from senders that refuse virtual lines.

Indonesia 500 MB: a prepaid travel eSIM with 500 MB of data for 1 day. Buy it when a traveller needs mobile data abroad without a local SIM card or roaming fees. Pay in USDC on Base with x402, no account or API key needed. The installable eSIM (QR code, LPA activation code, one-tap iPhone and Android links) is ready within seconds from order_status_url. Optional JSON body: quantity (1 to 20) and email.

Reasoning-puzzle dataset pack for AI agents from The Latent Lounge: 25 freshly generated puzzles where you infer a hidden string transformation from worked examples, then apply it — each with its verified answer and a worked explanation, as JSON in one x402 payment. Unscored and separate from the leaderboard; licensed for training and evaluation use.

List a wallet's native ETH and USDC balances with human-readable amounts. Canonical wallet-balance contract for autonomous agents: address plus optional CAIP-2 chain.

Extract title, description, Open Graph, Twitter cards, canonical URL, robots directives, headings, JSON-LD and other page metadata.

Detect meaningful webpage changes with deterministic hashes and diffs for prices, docs, policies, availability and competitor monitoring.

See which industries are unusually concentrated in a U.S. county using validated BLS QCEW location quotients, employment shares and wage comparisons.

Infer a JSON Schema (draft-07) from a sample document in any supported format. Types are inferred, present keys are marked required, and heterogeneous array item schemas are merged. The result validates out of the box with /v1/validate.

Infer a JSON Schema (draft-07) from an example value, walking objects and arrays recursively. Set detectFormat=true to tag strings that look like date-time/date/email/uri/uuid, requireAll=false to leave object properties optional, and additionalProperties=true to allow extra keys.

Restate an amount from one year in another year's money, for any country in the World Bank consumer-price series (1960 onwards). Returns the adjusted amount, the cumulative inflation and both index values so the arithmetic is checkable. The series is annual and published with a lag, so a request for a year that does not exist yet answers with the newest one available and says which. For contract comparisons, historical pricing and long-running budgets.

Returns harmonised consumer price inflation for several countries over a period, taken entirely from the European harmonised index so the numbers are actually comparable. That constraint is the product: national consumer price indices use different baskets, treat owner-occupied housing differently and rest on different base years, so placing them side by side produces a comparison that looks valid because everything is expressed in percent and is not.

Infoharmoni Atlas Pro, sellers.csv: Every x402 seller in today's registry snapshot, one row each: what it sells, its price, the registry's own call counts, and beside them the x402 payments read off Base in the last window, payer wallets and who the top payers are.

One x402 seller's report card before you pay them: what they sell, paid calls and payers in 30 days, price, rank of all sellers, rivals, and the day-by-day replay nobody else stored. Stamped with the snapshot date. Refusals are free.

Resolves two products to their RxNorm concepts and compares what the register declares about each: the active ingredient set, the strength per ingredient, the dose form and the route of administration. Every difference is listed individually rather than collapsed into a verdict, and matching ingredients with differing strengths are reported as such rather than as a match.
