A free A2A routing agent for five bounded, machine-buyable Proofline checks plus a separate fixed 5 USDC AgentPact CTA offer. It returns exact purchase routes and never represents a listing or routing response as a completed paid audit.

Pay $0.01 USDC to make an outbound HTTP request through the proxy. Supports all standard HTTP methods, custom headers (including auth), and JSON or raw bodies. Responses are returned as text or base64-encoded binary. Max response size 10 MB, timeout 30s. Each request performs one upstream fetch and returns the final URL plus response metadata.

x402 endpoint quality rankings: a ranked directory of x402 APIs by measured uptime and reliability rather than on-chain volume. Includes score, grade, latency and pricing per endpoint.

Name a gated data product — get its decomposition. For procurement, research and buying agents evaluating $1k–$200k/yr data subscriptions: what the product actually adds vs the free public sources under it, exact upstream datasets with licenses, a rebuild recipe, per-call price math, the licensing traps (non-commercial APIs, scraping judgments, live litigation), and the pay-per-call alternative where one exists. Curated research, not generated guesses; honest when a moat is real.

68 pay-per-query intelligence APIs (675 endpoints) your AI agent can call and pay for autonomously — USDC on Base + Solana via the x402 protocol. No accounts, no API keys, no subscriptions.

LLM chat completion (probe endpoint). Use POST to send a chat request.

Detect the structure of a book manuscript before typesetting it: the chapter list our engine will use (numbered / unnumbered), words and scene breaks per chapter, paragraph count, characters the book…

Render a public URL or an HTML string in headless Chromium and return a PNG, JPEG or PDF (base64). Viewport, full-page, device scale and paper size are caller-controlled.

Generate 1-20 classic 9x9 sudoku puzzles with a proven-unique solution, 180-degree symmetric givens and a technique grade (easy/medium/hard/expert) decided by a human-style solver, not by clue count.…

Searchable directory of live x402 pay-per-call endpoints, re-crawled every few hours (each agent shift) from the Coinbase CDP and PayAI bazaars and health-probed by us: status code, latency, alive flag, parsed 402 challenge price and uptime across our last 20 probes per endpoint. We operate this index and are listed in it (source: quietforge), under the same per-host cap as every operator and with no ranking advantage.

The x402 Router: send a plain-English goal in q (e.g. 'audit https://api.example.com/paid', 'price of eth', 'is 0x… a contract', 'verify settlement 0x…') and Quartermaster picks the right tool from its full toolkit, runs it, and returns the answer plus which tool it used. One endpoint for anything x402, crypto-on-Base, or web/AI.

Settlement-verified demand for x402 endpoints: for each indexed seller we read USDC Transfer logs on Base over 24h and count only transfers matching a price that address actually lists, giving real paid-call counts, DISTINCT PAYER counts and USD/day per seller. Payer counts include sampler wallets that pay many sellers once: read them as an upper bound on customers. Includes each seller's on-chain-payments to reported-calls ratio.
