Every agent-payable API.

Checks current registry metadata for deprecated, yanked or removed releases. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.

Deepstate, the on-chain order-book exchange on Robinhood Chain. Depth heatmap - resting order size by price level over time for a market.

Crypto perpetual-futures data from on-chain perp DEXs: per market the funding rate (hourly + annualized %), open interest (USD and base units), mark & oracle price, 24h volume and 24h price change. Ranked by open interest; filter by `coins` or `limit`. Data source: Hyperliquid (dYdX fallback).

Derive an Ethereum address from a public key — Genesis402 / UnyKorn Operator Network

Derived metrics: Ethereum gas price sampled continuously in the background and turned into rolling average, min/max, volatility, and trend direction over a window (?windowMinutes=, default 10) — none of which exist in the raw upstream feed's single instantaneous value.

PII sanitization for AI agents

Full descriptive summary of a numeric sample: count, sum, min/max/range, mean, median, mode(s), variance, standard deviation and the quartiles (q1/q3/iqr). Set sample=true for the sample variance/stdev (÷ n-1) instead of the population form (÷ n).

Detailed data for a single token (by contract address)

Find personally identifiable information in a text blob: emails, phone numbers, credit cards (Luhn-validated), IBANs (mod-97 validated), IPv4/IPv6 addresses, US SSNs and JWTs. Returns every match with its type and character offsets, plus per-type counts. Validated — not just pattern-matched — to keep false positives low. Fully offline.

Detect the language and script of a text — Genesis402 / UnyKorn Operator Network

Detect whether a User-Agent belongs to a known bot, crawler, AI agent or HTTP tool, and if so return its name and category (search, social, seo, ai, monitoring, tool, …).

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. Sibling of Delx routes that alread…

Guess the character set of a base64-encoded byte buffer: sniffs a byte-order mark, then falls back to ASCII / UTF-8 validation and a UTF-16 NUL-pattern heuristic. Returns a best-effort charset with a confidence label — a low-confidence guess is still a successful 200.

Detect common SPF mechanisms present in a TXT record. Call when quick SPF mechanism inventory without DNS lookup. Returns flags for include/a/mx/all 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.

Detect shipping carrier from tracking number format and provide tracking URLs. Supports UPS, FedEx, USPS, DHL, Royal Mail, PostNord, and more. Algorithmic.

Detect the issuing network/brand (Visa, Mastercard, American Express, Discover, Diners Club, JCB, UnionPay, Maestro) from the card's IIN prefix, with the network's valid lengths. Returns `network:null` for an unrecognized prefix.

Add words to narrow by title or author. Re-verified daily. $0.01 per page of 20.

Compute the determinant of a square matrix via Gaussian elimination with partial pivoting. A non-square, ragged or empty matrix is a clean 400; a singular matrix simply returns 0.

Deterministic citation formatter — APA 7, MLA 9, Chicago 17 author-date, BibTeX. From structured fields, returns the reference entry (markdown/html/plain) + the in-text citation, reproducing published style-manual examples exactly. For full author lists use POST. Every answer signed. Free sample, no payment required: GET /play/cite

Deterministic HS-code triage: ranked candidate headings with official heading text, GRI note and broker disclaimer. Not a customs ruling.

Deterministic UUID v5 from a name — Genesis402 / UnyKorn Operator Network

A ranked, tagged digest of the last 24h of high-signal developer news (AI, devtools, security, infra) with scores, links, and discussion volume. Built from public Hacker News data.

AV/IT device integration facts for AI agents writing drivers and integrations: control protocol family, transport, TCP/UDP port, connection notes and field-tested gotchas for professional audio-video, lighting, shading and network devices (Crestron, Samsung, Shure, Somfy, Huawei, MikroTik and more). Curated first-hand by working systems integrators.

Canonicalizes device_id, nonce and message, computes an HMAC-SHA256 tag with caller-supplied ephemeral key material, and optionally compares a claimed tag in constant time. It does not provision devices, store keys or replace asymmetric device identity; do not submit long-lived production secrets.

Query paginated EU EUDAMED device dataset for regulatory/compliance analysis.

DEX aggregator trading volume: total 24h/7d/30d USD volume with 1d/7d change, plus the top aggregators (1inch, CowSwap, Jupiter, etc.) by 24h volume. Optional chain filter scopes the totals and ranking to one chain.

Find DEX liquidity pools for a token contract address or search term (symbol/name) across Ethereum, Base, Solana, Arbitrum, BSC and more: price, USD liquidity, 24h volume and buy/sell counts, 1h/24h price change, FDV and market cap, sorted by liquidity.

DEX trading volume: 24h/7d by protocol, all chains or one chain — Genesis402 / UnyKorn Operator Network

Screen a person, company or vessel name against the US Treasury OFAC Specially Designated Nationals list AND its alias file - aliases matter, because a sanctioned party usually trades under an aka. Each match carries a deterministic score, the sanctions programme, and whether the hit was a primary name or an alias. The response lists which lists were searched and which were not: a name-similarity search, not a compliance determination.

Read any wallet balance on 28 EVM chains: native coin (ETH, BNB, MATIC, AVAX) or any ERC-20 token including USDC. Covers Base, Ethereum, Arbitrum, Optimism, Polygon, BSC, Avalanche, zkSync, Linea, Scroll, Blast, Mantle, Celo, Gnosis, Sonic, Unichain, World Chain, Zora and more. Returns the raw and decimal balance with the block it was read at.

Hourly electricity generation by fuel source for any US balancing authority, with the carbon-free share computed from wind, solar, hydro, nuclear and geothermal. Storage is excluded from both sides because discharging shifts power rather than generating it, and "other/unknown" is never counted as clean - so the share errs low. Method returned with the numbers.

Chat completions for GPT-5.6, DeepSeek V4 and Gemini behind one OpenAI-shaped endpoint. No account, no API key: the request pays for itself in USDC on Base, Polygon, Arbitrum or Solana. Pay with the upto scheme and only what you actually use settles - the unused ceiling comes back.

Turn speech into text: send base64 audio, get a plain transcript back. Handles WAV, MP3, FLAC and OGG up to about eight minutes per call. Priced per call with x402.

Look up any transaction and its receipt by hash on 28 EVM chains: success or revert, block number, gas used, effective gas price, sender and recipient. Covers Base, Ethereum, Arbitrum, Optimism, Polygon, BSC and more. Use it to confirm a payment or settlement actually landed.

Execute a service published by an external agent on the DexL network, paid per call with x402

Summarize text into a set number of sentences, or into bullet points. Uses only what the text says and adds nothing. Input is bounded at 8000 characters, which is what makes a fixed price per call possible instead of per-token billing.

Make any read-only JSON-RPC call on 28 EVM chains - eth_call, eth_blockNumber, eth_getLogs, eth_getBalance and the rest - without running a node or holding an RPC key. Covers Base, Ethereum, Arbitrum, Optimism, Polygon, BSC and more, with automatic failover across providers when one rate-limits or goes down.

Hourly US electricity demand, day-ahead demand forecast, net generation and total interchange for any of 83 balancing authorities - CAISO, ERCOT, PJM, MISO, NYISO, ISO-NE, SPP, Bonneville, or US48 for the whole Lower 48. Straight from EIA open data, grouped by hour so an agent reads one object per hour instead of four raw series.

Fetch any public web page or JSON API and get its status, content type, headers and body back. For agents that need to read a page they cannot reach themselves. Private networks and loopback addresses are blocked, and large bodies are truncated rather than dropped.

Read a token's DEX pair straight from the chain: pair address, both reserves, the implied price, LP total supply and how much of that LP sits in burn addresses. Base, Arbitrum and BNB Chain, Uniswap V2-style factories against the wrapped native token. Read-only eth_call, no API key. The answer states its own limits: no pair here does not mean no liquidity, because V3, other DEXes and non-native quote pairs are not covered.

Run a DexL agent autonomously: it plans, discovers services, pays for them, executes and verifies - paid for once with x402

Translate text into any target language, detecting the source when you do not give it. Proper nouns, numbers, code and formatting are kept as they are. Returns the translation alone, with no preamble to strip. Fixed price per call.

Sentiment as one of positive, negative, neutral or mixed, with a -1 to 1 score and a one-line reason. "Mixed" is a real answer, not a rounding of the two directions - and an answer outside the four values is rejected rather than returned. Fixed price per call.

Pull named fields out of free text as JSON - names, dates, amounts, references, anything you list. Every field you ask for appears in the answer: one the text does not contain comes back null rather than guessed, so "not in the text" and "model did not answer" are never confused. Fixed price per call.

Run a DexL agent: the model reasons, calls tools when it needs them, and returns an answer - paid per run with x402

Assign text to one of the labels you supply - support tickets, intents, topics, spam or not, anything. The returned label is checked against your list, so the model cannot invent a category: an answer outside your labels is rejected rather than passed through. Comes back with a confidence and a one-line reason. Fixed price per call.

Euro foreign-exchange reference rates from the European Central Bank for 30 currencies - USD, GBP, JPY, CHF, TRY, CNY, INR, BRL and more - with cross-rates derived through EUR (USD/TRY, GBP/JPY, anything against anything) and an optional daily series up to 90 business days. The response says plainly what these are: published once per business day around 16:00 CET, not a live market rate and not tradeable.
