Agent & Infrastructure

Forward geocoding for AI agents: turn a place name or address into coordinates. Returns the best-match latitude, longitude, country and ISO country code, administrative regions (admin1/admin2), population, IANA timezone and GeoNames feature code. Query by q= or address=. Sourced from Open-Meteo geocoding — keyless, unified schema, stablecoin-payable.

Prompt Injection Guard: Keeps an AI agent from obeying instructions hidden in what it reads (indirect prompt injection). Web pages, e-mails, files, PDFs, API and tool output, other agents' messages and skill files under review are treated as content, never as orders. The agent is instructed never to pay, transfer, delete or reveal anything because content asked, to report the attempt with a quote and its source, and to still finish the real task. Use whenever the agent reads anything it did not…

x402 Buyer: Pay Safely from an Agent Wallet: Decision rules for an AI agent that holds a wallet and receives an HTTP 402 payment request (x402 v2). Decides SIGN, REFUSE or ASK the human before any money moves, and says how to verify the delivery and retry without paying twice. Use when an agent is about to pay over x402, gets a 402 response, must check a seller's payment terms, or a paid request failed and it is unsure whether to pay again. One-time purchase of the SKILL.md file (Agent Skills f…

Humanize AI Text: Rewrites AI-sounding prose so it reads like a person wrote it — in any language, without dropping facts. Use when asked to humanize a text, make it sound less AI-generated or less like ChatGPT, or clean machine phrasing out of an article, post, email, product description or page. One-time purchase of the SKILL.md file (Agent Skills format), $0.05 USDC, yours forever incl. free re-downloads and new versions. Tested with a strong and a weak model; the card tells you where the we…

Entailment scoring: does the provided context support this claim? Research agents use this to self-check outputs.

Decision-ready x402 builder brief in one call: demand movers, underserved categories, new competitors, price anomalies, host concentration, and three scored opportunities with evidence and caveats.

x402 preflight / reputation — verify BEFORE you pay. Give it an x402 endpoint_url (or a payTo address) and it returns, in one cheap deterministic call: is the resource reachable, is it present in the CDP Bazaar discovery catalog (serviceName, declared payTo, price, network, tags, last_seen), and — the key integrity check — does the payTo the endpoint actually demands in its live HTTP 402 challenge MATCH the payTo the catalog advertises (payTo_match). It runs a keyless HEAD/OPTIONS/402 probe that never moves funds, extracts the real payTo/amount/asset/network from the challenge, scores listing freshness, and — if you pass a prev snapshot {payTo,amount,lastUpdated} — flags whether the endpoint changed since you last saw it (anti-rug). Output is a 0-100 scorecard + letter grade + reason codes + an actionable verdict (pay_ok / caution / do_not_pay). For any router, wallet agent or M2M client that pays third-party x402 endpoints and needs to avoid paying a hijacked, dead, or repriced resource. Deterministic, no LLM, Ed25519-signed. 0.01 USDC via x402 on Base. SYNTHORA.

Like /x402/find, but the shortlist is re-checked right now: we send each top candidate one unpaid request and keep only those answering with a valid x402 price quote, with live price and response time. Plain-English job in, such as 'web search api' with a budget per call; working services out. Never pays them.

What's growing in the x402 economy: services with the biggest rise in unique buyers over the last N days, from our own daily history of the Bazaar catalogue (history started 2026-09-28 and grows every day), over a window of 1 to 90 days (7 by default). For builders, investors and agents choosing reliable providers.

Black-box check: does the x402 endpoint verify payment (reject forged txHash/signature/replay) before delivering? Buyer-side trust check before you pay. Returns SAFE/RISK/NOT_X402.

Find the best tool for a job. Describe the task in plain English (e.g. 'check if a token is a rug pull', 'scrape a page to markdown', 'cheap LLM chat') and get a short ranked list of pay-per-call x402 APIs and MCP servers side by side: what each does, exactly how to use it, price, reliability from our own checks, and why it fits. Neutral: ranking is never paid, and you call and pay each tool directly.

Code Review: Reviews a code change (a diff or a changed file pasted as text) and reports real problems ranked by severity — correctness bugs, security holes, data loss, missing error handling, edge cases, resource leaks — each with location, reason and a concrete fix in words. Use when asked to review code, a diff or a pull request, check a change for bugs, or find security problems in a snippet.

Describe a job in plain English, such as 'scrape a web page to markdown', and get the best working x402 services for it, ranked on fit, real buyers (30 days), our uptime and speed checks, and price, with reasons and how to call each. You can set a budget per call. Covers the whole x402 Bazaar catalogue: crypto, search, scraping, LLMs, enrichment and more. For a shortlist re-checked right now, use /x402/find/live.

Live health check of any x402 endpoint before you pay it: is it up and answering 402, is the payment request valid, prices in USD per network, pay-to wallets, x402 version, Bazaar discovery metadata, response time, and its buyers in the Bazaar. Never pays the endpoint. Give the endpoint's URL and how it is called (GET or POST). For our own endpoints the answer comes from our in-process monitor (a Worker can't call its own address).

Latest posts from any site or feed as clean JSON: pass a feed URL or just the site's address and we find its RSS, Atom or JSON Feed (from the page's links or common paths), then return titles, links, dates, authors and summaries, newest first. For monitoring blogs, changelogs and news. ?url=https://blog.cloudflare.com&limit=20

Generate cryptographically random UUIDv4s or time-sortable UUIDv7s from a real CSPRNG, and validate any UUID's format, version and variant bits. Use this when an agent needs to random v4, sortable v7, plus strict validation.

Renders a finished one-page equity tearsheet PNG for a US-listed stock — not raw JSON to assemble. Fans out to profile, price, 1-year history, fundamentals, technicals and news, then draws a 1-year price chart with its 50-day average plus key stats (market cap, P/E, margins, dividend yield, 52-week range) and headlines. Returns the data plus a hosted `artifact.png_url`. From x402stock
