Bitcoin hash-ribbon miner-capitulation signal: the 30-day versus 60-day moving average of network hashrate, whether miners are in capitulation, whether a recovery cross has occurred, and the 30-day hashrate trend. Informational, not advice.

Bitcoin mining hashprice: expected mining reward per petahash and per terahash per second per day, in BTC and USD, fused with the network hashrate, current difficulty, the next difficulty-retarget forecast and the block-subsidy and average-fee split. Informational, not advice.

Pick the cheapest LLM that passes your task and constraints. Give a task class and optional constraints such as minimum context, required tool-use, vision or reasoning, maximum input and output price per million tokens, a minimum coding benchmark and a provider filter, and get a ranked cheapest-first list of models that pass, plus a recommended pick and a deterministic rationale. Fused from open keyless catalogs LiteLLM, models dev and Aider with a citation on every model.

Split an integer amount of cents among N ratios with zero rounding loss (Fowler's allocation algorithm) - the parts always sum back to the original amount.

Format a numeric amount with thousands separators, a chosen decimal precision and a currency symbol.

native token dispatch for autonomous agents

nbx4: Base owner, proxy and token metadata with block evidence, best-effort source match and observed snapshot comparison

Preliminary, limited EVM mechanism evidence from a block-pinned snapshot: matched source syntax, proxy and token state, and optional V2 pool observations. Unknowns remain unknown; not a security audit or sellability verdict.

Solana SPL Token / Token-2022 mint and extension observations from finalized RPC; unknowns remain unknown. Free preparation returns an immutable report ID; paid read costs 0.01 USDC on Base. Not a sellability or safety verdict.

Flagship NFT collection intelligence: fuses identity, floor (native+USD), market cap, volume, total supply, holders and listed count into COMPUTED metrics — liquidity ratio (listed/supply + volume/mcap), holder/supply ratio, sales velocity and floor momentum — plus a normalized market-health verdict with confidence and rationale. EVM via CoinGecko, Solana + Bitcoin-Ordinals via Magic Eden. Keyless, attributed.

Should my agent pay these x402 endpoints? Up to 25 listings from nohumans.directory in one call: pay, caution or avoid for each, with plain reasons, including whether we bought it with real USDC and it delivered.

nohumans.directory demand clusters: what agents searched this directory for over the last 30 days, grouped by meaning rather than exact wording, with searches and distinct-client counts per cluster. Self-monitoring sellers excluded, exclusion published; k-anonymity floor of 3 clients per cluster. The free tier at /v1/demand is the same shape, delayed. Money buys currency and the clustering — never raw queries or client identifiers.

nohumans.directory pre-spend verdict for one listing: probe history, payTo age and stability, paid-delivery outcome, verified verb, and a pay/caution/avoid verdict with reasons.

Normalized multi-period Form 990 financials for a US nonprofit by EIN: revenue, expenses, contributions, program revenue, assets, liabilities, net assets and officer compensation per tax year, plus computed ratios (program support, overhead, officer-compensation share, net margin) and gap flags, each number cited to its filing.

npm breaking changes between two versions of a package, before a package upgrade: the documented breaking changes per version, read from the real CHANGELOG, GitHub release notes and alpha/beta/rc notes, plus major version bumps, Node.js engine, ESM/CJS, exports and peer dependency changes, migration guide links and a verdict. Exact versions or a major ('4'); a source URL for every item. One call per dependency upgrade.

npm changelog between two versions: the full release notes of every version in the range (newest first, up to 100), from the package CHANGELOG and GitHub releases, with publish dates, bump type (major, minor, patch), npm deprecations, extracted breaking changes and package.json manifest changes. Covers a whole package upgrade or dependency upgrade in one call instead of reading dozens of release pages.

An npm package's latest version, description, license, repository, dependencies, peer dependencies, TypeScript types, size, publish dates, deprecation and weekly downloads. Use to choose or audit a JavaScript dependency.

Check npm's official status source for current incidents, component health, and scheduled maintenance before an agent retries, deploys, or escalates.

Download counts of an npm package for the last day, week and month, from the official npm registry API. Use to judge how widely a dependency is used.

Signed full 50-state plug-in solar legality dataset. Free preview: GET /solar-legality/preview If the signer is unavailable it returns 503; you are never charged for an error.

Convert a number's string representation from one base (2-36) to another.

Convert an integer (1-3999) to a Roman numeral, or a Roman numeral back to an integer.
