Every agent-payable API.

API endpoint health checker and x402 compatibility scanner. Provide target url to fetch and check if it correctly implements the HTTP 402 payment flow, and extract its pricing requirements.

Deterministic greenhouse gas inventory API for auditable Scope 1, 2, and 3 accounting from explicit activity records. The accounting step pairs with Viridis embodied-carbon takeoff, disclosure, and tax-credit engines.

Returns verified, citation-backed facts about new AI model releases, benchmark scores, and protocol changes, each with source URLs and confidence.

Returns clean, normalized datasets of AI model benchmarks, pricing, leaderboard scores, and Ethereum EIPs, parsed from sources that are costly to scrape.

DripMetricsAI (api description at https://dripmetrics.ai/) provides on-demand market microstructure and risk metrics for agents and developers. Agents can pay per request via x402 and receive structured JSON metrics without subscriptions or API keys. VPIN measures volume-synchronized order-flow imbalance (an adverse-selection proxy, not a probability); see excessVpin. Discovery examples use the latest 30m window.

Real-time current weather conditions for a city or location, including temperature, humidity, precipitation, wind, and a human-readable condition.

Fetch any public web page and return clean main content as JSON: title, author, publish date, hostname, excerpt, full text, and word_count. Boilerplate (nav, ads, footers) is stripped. Input: url (public http/https). Use to read articles, docs, or pages and feed clean text to an LLM.

Fetch a URL and return clean readable text. No LLM, flat rate.

Read any web page or article: fetch up to 5 URLs in one batch call and extract the main content as clean, LLM-ready markdown or plain text. Convert webpages to markdown, scrape page text, pull article content for RAG ingestion and AI agent context.

Deep web research for AI agents — advanced search returning the highest-relevance results with multiple query-focused snippets per source, plus an optional LLM-generated answer grounded in the returned sources when include_answer is set. One-call research assistant for high-precision queries; news and finance topics, date and domain filters.

Web search returning URLs, titles, and descriptions

Exact date arithmetic — the calendar math LLMs guess at. ?from=&to= → days, business days, weeks, hours between; ?date=&add=30d|2w|3m|1y|10bd → the resulting date (bd = business days); ?date= alone → weekday, ISO week, day-of-year, leap year, unix. All UTC, Mon-Fri business days, real-calendar validation (Feb 30 is rejected).

Elixir lint / debug kit: POST {code}, get the bugs back with line numbers. Deterministic static analysis — code is parsed, never executed, no AI. Catches unbalanced do/end and brackets, missing do, 'return', '+' string concat, trailing commas, field assignment, = vs == in conditions and guards, block-scoped rebinding (the classic), charlist vs String mixups, unused variables. Errors, warnings and hints with fixes. Max 128 KB.

Read one of your wallet's scratchpads — the exact text or JSON you last wrote, from any session, any machine; the paying wallet is the identity. Add ?raw=1 for the bare document instead of the JSON envelope. Reading extends the pad's life 30 days.

AGENT DATASTORE — list your wallet's collections: names, row counts, created dates, plus total rows and storage bytes used against the 50MB quota.

JavaScript / Node lint: POST {code}, get the bugs back with line numbers. Syntax errors come from the real V8 parser (compile-only — code is never executed), plus deterministic checks: loose == coercion, assignment in conditions, comparisons with NaN, const reassignment (runtime TypeError), var pitfalls, unused variables, leftover console.log. Handles ESM imports, template literals, regex. No AI. Max 128 KB.

HTML → Shopify section converter. POST static HTML; get back a drop-in theme section: headings, paragraphs, images, links, and buttons are lifted into {{ section.settings.* }} references and a matching {% schema %} is generated with your original content as the defaults — immediately editable in the Shopify theme editor. Deterministic transform, no AI; output is self-linted before it's returned.

AGENT DATASTORE — drop one of your wallet's collections and all its rows. Cheap on purpose: clean up after yourself and stay under quota.

PHP lint: POST {code}, get the bugs back with line numbers. Deterministic static analysis — code is never executed, no AI. Catches SQL injection (request data interpolated into query strings), the removed mysql_* API, unbalanced braces, '+' string concat, = vs == in conditions, type-juggling loose comparisons, eval/extract on request data, unused variables, leftover var_dump. Understands PHP tags, heredocs, interpolation. Max 128 KB.

Uptime/health probe for any public URL: sends a HEAD request (auto GET fallback when the server refuses HEAD), follows redirects with per-hop safety checks, and returns up/down, HTTP status, latency in ms, redirect chain, final URL, and key response headers. Deterministic, no page download — a monitoring probe agents can call on a schedule.

Cheapest liveness ping: ONE request to any public URL — is anything answering, and how fast? Returns up/down, HTTP status, and latency in ms. Any HTTP response below 500 counts as up; redirects are reported, not followed. High-frequency monitoring loops belong here; step up to /api/uptime for redirect following and headers, /api/uptime/report for the full timing/TLS/CDN report.

Barcode generator for product, shipping, and inventory labels: GET ?data=&type= and receive a print-ready SVG plus PNG (base64) and a data: URI. Types: code128 (default), ean13, ean8, upca, upce, code39, itf14, gs1-128, codabar, datamatrix, pdf417, aztec. Check digits, quiet zones, and the human-readable line are handled per spec; invalid input for a symbology returns a clear 400. Deterministic, no network. QR codes live at /api/qr.

List your wallet's scratchpads: names, sizes, updated and expiry dates. The cheap 'do I have memory here?' call for the start of a session.

Exact financial + token math. POST {op:…}: compound (growth with per-period contributions), amortize (payment, total interest, schedule), npv, irr (deterministic bisection) — and token_units: exact decimal↔base-unit conversion via BigInt for any token decimals (ETH 18, USDC 6), the 18-decimal math that float64 silently corrupts. Iterative series computed exactly, never guessed.

Exact descriptive statistics — LLMs cannot reliably sum 200 numbers; this can. POST {values:[…]} for count/sum/mean/median/stddev/percentiles; {x:[],y:[]} for Pearson correlation + linear regression; {rows:[…], field} for object arrays — or {collection, field?} to run stats DIRECTLY ON YOUR DATASTORE collection (the paying wallet is the identity; reading extends its life 30 days). Up to 100k values, Kahan-summed.

Live crypto conversion at CoinGecko prices: any coin to any coin or fiat, and fiat to coin. ?amount=0.5&from=bitcoin&to=ethereum — common tickers (btc, eth, sol…) accepted. Returns the rate, the converted amount, and the underlying prices. Prices cached ≤30s; cheap enough to call in a loop.

What is this website built with? Deterministic fingerprinting from one fetch — like the old meta generator tag, but it works even when sites strip it. Detects WordPress, Shopify, Squarespace, Wix, Webflow, GoDaddy, Drupal, Joomla, Ghost, Magento, Next.js/Nuxt/Gatsby/Astro and other frameworks, static HTML, custom PHP — with the evidence for the verdict, the raw generator tag when present, and the server/CDN stack. No AI.

L2 ORDER-BOOK DEPTH — the live bid/ask ladder for any crypto pair, normalized across Coinbase, Binance.US and Kraken (auto-fallback, or pick a source). Returns bids/asks to your depth plus the analytics that matter: mid, spread (absolute + bps), book liquidity per side, and slippage estimates for $1k/$10k/$100k market orders both directions. Deterministic, no keys, ~1.5s cache. ?pair=BTC-USD&depth=50&source=auto

SITE-WIDE audit — the full 7-part on-page audit (head/meta, alt text, social cards, links, WCAG, schema.org, robots) run across up to 8 pages of one site in a single call. Discovers pages from the start URL's internal links, audits each, and returns per-page scores plus a site-level score, grade, and the issues that repeat across pages. The finished deliverable: one call, whole-site verdict. ?url=&pages=&level=&detail=

Webbie page generator: site name, headline, tagline, hero images, content sections, nav, colors — returns a finished responsive standalone HTML page. Three templates (horizon, split, editorial); the seed deterministically picks template + fonts + accent, so reusing it across calls builds a consistent multi-page site. Nav loads from an editable nav.json at view-time. No AI — deterministic templating.

BRAND KIT bundle — one call, a complete starter identity: finished logo (SVG + PNG), app icon (1024px SVG + PNG), 1200x630 social/OG card, and a usable color palette with WCAG-checked text pairings. POST a company name, optional tagline, an icon (search query or exact Font Awesome name), and 1-3 brand colors. Everything matches: same mark, same colors, same fonts. The pieces individually total ~$0.05; the kit is $0.05 and adds the palette and coherence.

Fetch any public web page and return its main content as clean Markdown, ready to feed to an LLM. Boilerplate (nav, ads, footers) stripped. Input: url (public http/https). Returns {url, markdown, word_count}.

Historical performance by day of week (avg return + win rate per weekday) over the lookback. Use to time entries/exits around statistically stronger or weaker days. Seasonality, not a forecast.

Convert a weight/mass value between units (kg, g, lb, oz, stone, tonne, and more).

Flow, not snapshot: the largest transfers of a Base token in the last 24h, classified by whether whales are sending INTO DEX pools (sell pressure) or pulling OUT (accumulation) — a net sell-pressure read that decays in hours. Complements holder-forensics ('who could dump') with 'is anyone dumping now'. CDP-indexed events.

Whole-market snapshot: total crypto market cap, total 24h volume, BTC dominance, and counts of active coins and markets. One call for the macro state of crypto — the top-of-funnel context before drilling into an asset.
