ERC-20 name/symbol/decimals on Base for $0.001 USDC via eth_call. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

Levenshtein edit distance and similarity for $0.001 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana.

Detect blank or whitespace-only strings before paying downstream — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls.

Fetches the recent notes of one public key across several relays and measures six independent signals: posting rate per day, the coefficient of variation of the intervals between posts, how many of those intervals sit within a few seconds of each other, the entropy of the hour-of-day distribution, the share of posts whose text repeats an earlier post verbatim, and the largest burst inside sixty seconds.

Fetches kind 3 contact lists over up to twelve relays. Because kind 3 is replaceable, several relays regularly hold different versions; only the one with the highest created_at is used and the answer states which relays carried that version and how many older versions were seen, so a stale relay never quietly overwrites a current list. At depth 1 the answer is the account and its outgoing follows.

Proprietary dataset: AI-visibility scores (0-100) for 25 major brands across 5 industries (trucking, project management, website builders, CRM, AI code editors), measured by whether an LLM names them in answers to real buyer questions. Includes mention counts and which competitors AI names instead. Refreshed each edition. For market-research, brand-monitoring and GEO agents.

Normalises what a package version declares about where it can run. For npm that is the engines, os and cpu fields plus the declared package type and whether native build scripts are present; for PyPI it is requires_python together with the operating system, implementation and Python version classifiers.

Polymarket odds movers: active markets ranked by biggest price swing in the last 1h / 24h / 1wk (window param), with yes price, change and direction, best bid/ask, spread, 24h volume, liquidity and end date. The momentum signal prediction bots scan before entering a market. No charge on service failure. Ed25519-signed. $0.10 USDC per call via x402 on Base. Free trial: 3 calls per wallet with header X-WALLET.

Polymarket resolution watch: markets ending within N days (default 7) with UMA resolution status (proposed/disputed), UMA bond and reward, hours to resolution, last price, 24h volume, liquidity and a uma_risk flag for contested or undecided resolutions. Lets prediction agents avoid or exploit resolution risk. No charge on service failure. Ed25519-signed. $0.10 USDC per call via x402 on Base. Free trial: 3 calls per wallet with header X-WALLET.

The EIP-155 chain ID for any supported network via eth_chainId — the read multi-chain agents make to confirm which chain an RPC is on before signing. Across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Free public RPC; undercuts onesource (Ethereum-only) at $0.001 on 6 chains.

Look up any transaction by hash: confirmation status (success/failed/pending), block number, confirmations, value, from/to, fee paid, gas used, and the decoded method. The read every settlement, trading, and payment agent polls after sending a tx to confirm it landed. Across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Free upstream (Blockscout); one paid call instead of running your own RPC.

Current Hacker News top stories with score, author, comment count, and links. For tech-trend, sentiment, and news-monitoring agents. Live from the Hacker News API.

The current chain tip (latest block height) via eth_blockNumber, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. The freshness read settlement, indexing and trading agents poll to know where the chain is. Live public RPC; one paid call at $0.001.

Measures how well an area is equipped for cycling from four things that can actually be counted. Separation from motor traffic is the heaviest factor and is ranked explicitly: a physically separate track, a painted lane on the carriageway and a shared bus lane are three different levels of protection, the ranking used is returned with the result, and roads carrying cycle traffic with no provision at all are counted as the fourth level.

Collects the observable signs of a route hijack for one prefix and reports which of them are present, with the measurement behind each. Four signs carry different weight. RPKI invalidity is the only hard one: a ROA exists and does not authorise this announcement. An origin AS that appears in the current state but nowhere in the history window is the classic sign, and the response gives the historical origins so the change can be dated.

List registered X accounts your wallet owns or has shared access to.

Approximate short liquidation price from entry, leverage, and maintenance. Call when risk banners for leveraged short positions (advisory model). Returns liq price estimate for short as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

HSTS Policy Check: HSTS Policy Check checks HSTS max-age and subdomain directives against caller policy from bounded caller-supplied values without an external provider. Call HSTS Policy Check before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for HSTS Policy Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, m…

DNS DMARC Policy Parse: DNS DMARC Policy Parse parses DMARC policy, percentage, alignment, and report tags from bounded caller-supplied values without an external provider. Call DNS DMARC Policy Parse before applying a DMARC policy parsed from a caller-supplied record. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS DMARC Policy Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party, stateless, mem…

CSP Directive Parse: CSP Directive Parse parses Content-Security-Policy directives into normalized source lists from bounded caller-supplied values without an external provider. Call CSP Directive Parse before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for CSP Directive Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or Solana. First-party,…

Detect RFC1918 private IPv4 addresses. Call when agents classifying IPs before whois/network calls. Returns is_private as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Check sitemap and robots hints fast to see how a site exposes crawlable structure for $0.01 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

Looks at every AS path observed for a prefix and reports the ones that do not fit. Four patterns are checked. A path loop, where an AS appears twice with other ASes in between, which prepending does not produce and a leak does. An unusually long path, measured against the median length of all paths to the same prefix rather than a fixed number, because path length is a property of where you sit in the network.
