Keyword-route a natural-language need to the best Rainmaker well ($0.005 USDC via x402). Returns well id, origin, tool, price_usd, mcp URL, and why. After recommend, open that origin's /mcp directly — gateway does not proxy (avoids double-charge). Free alternative: list-wells.

Machine Observer premium historical snapshots across machine commerce, trust, likeness, API/data, compute, model/tool supply, and developer-adoption signals.

Use this when you need to share a file with another agent or a human: upload base64 content or a URL and get a short-lived, zero-log download link with TTL (15m–7d) and optional burn-after-reading.

AI text summarization

Stylometric AI-writing detector (~78% in-sample bench; not field accuracy). Uncertain → invite longer sample (ideally 300+ words). Amp port — honesty preserved.

Example premium technology research report

Clean a CSV ($0.005 USDC): give an https url or inline csv (max 1 MB / 20k rows).

Returns cleaned CSV text + JSON report (rows in/out, dupes, columns changed). Deterministic, no AI. As is, no warranty. Nothing stored.

One Regelkartan pitfall row by id (GDPR, AI Act, ISO): rule, law, wrong, right; en + sv. Same data is free at thepocketoperator.com/pitfalls.json; you pay for the per-row API

Statically analyse a Model Context Protocol (MCP) server manifest for security risks. Tool descriptions enter the model context, a prime prompt-injection vector. Deterministic and offline (inline manifest). Flags dangerous capabilities (command/code execution, filesystem, credential and network access), injection patterns, hidden unicode and unconstrained parameters. Returns severity-ranked findin

ApexScout one-cent x402 proof. Buyer-controlled GET retry only; unpaid 402 is not revenue. Successful paid proof includes one free receipt-bound compatibility diagnosis.

0xBs public x402 demo — USDC on Base for agent-payable ESP32 hardware.

Which x402 API should my agent call? Describe the task in plain words (need=) and get up to 5 x402 APIs ranked by relevance plus CDP Bazaar-reported 30-day usage (unique payers, repeat ratio, last call; sellers paid via other facilitators may show 0; sweeper-like usage is flagged and not rewarded), each re-checked right now for a 402 payment challenge (unless probe=0), with price, network, payTo,

x402 preflight: before your agent signs a payment, fetch a paywalled URL's 402 and lint it. Parses v1 bodies and v2 PAYMENT-REQUIRED headers, then checks each accepts[] option: known network, canonical USDC, EIP-712 domain (extra.name/version) that a signature will verify against, EIP-55 payTo, zero/contract payTo, amount sanity, timeout, testnet, resource-host mismatch. Returns ok/warn/block per

x402 preflight: check any x402 endpoint BEFORE you pay it. Probes the target unpaid and returns its live price in USD, network, whether the asset is canonical USDC, payTo, timeout, mismatches vs the CDP Bazaar listing, and a pay / caution / do_not_pay verdict. Never signs or pays anything.
