response_scanUse when a buyer agent is about to act on a paid x402 response: post the body, or passages of it, with the seller's URL and get back instruction-like passages aimed at an agent, hidden characters, exfiltration links, a mismatch against the seller's declared output example, and w…

repeat_demandIs demand in my x402 category coming back? One signed number: 30-day repeat calls in a Bazaar category in the newest complete weekly snapshot (listings whose calls are at least twice their payers, so one-call-per-payer sweeps are left out) against the week before, with the repea…
proof_valueWhat is a proof worth at my x402 price? One signed number: the premium buyer-agent models gave a cue (a passed certification, an attested sample, pay on delivery, signed receipts, a pledge, the data-not-instructions declaration, or a fake payer count, urgency or an authority cla…
payer_mixWho pays this x402 address, in bands? One signed fact for a seller's pay-to on Base: the share of its payers, and of its revenue, in the last 7 days that looks like sweeps or graders, and the share that came back, each as a band (under 10%, 10 to 25%, 25 to 50%, 50 to 75%, over…

research_briefNot answering yet: brief=monthly answers from 1 Dec 2026. Until then, such a call is refused before any payment. One chapter of a research brief on the x402 market, in Markdown with every table also as JSON: a category (demand, prices, survival, rivals, proof), a launch at a pri…
insights_pageOne page of the weekly x402 demand insights report for $0.05, where the whole report is $0.25: repeat demand by category, demand gaps, movers, the price index with the listings that changed price, strong listings with weak descriptions, or GET against POST. Every metric of that…

job_statusFree: a ticket's standing, and its result once the run is done. A slow tool called with ticket=true answers with a job; pass its id here as often as you like. A failed run says why and when it will be tried again; it's owed a result.
registered_agent_cardFree: check an ERC-8004 agent on Base from outside, by its id in the Identity Registry: whether its registration file is valid and points back to it, whether its https endpoints answer and their domains list it, whether its x402 offer or A2A agent card passes the lint, and how c…
