− > Seller tools for x402 APIs, paid per call in USDC by the agents that use them: a listing lint, a Bazaar rank check, a Machine Buyer Panel that tests whether buyer agents pick your offer over its rivals, signed samples buyers can trust, and a demand gap finder for what to build next. Agoranome pledges 15% of settled revenue to a cause.− Pay with any x402 v2 client: scheme `exact`, network `eip155:8453` (Base), USDC. Call a paid route without payment to get its 402 offer (PAYMENT-REQUIRED header), then retry with the PAYMENT-SIGNATURE header. Every price is at or under $1, the default spend cap of the official x402 clients. A call that fails is never settled, so you aren't charged for it.− Over HTTP, pay by card instead for the Machine Buyer Panel ($1.00) and Demand gap finder ($1.00): their 402 also carries a Machine Payments Protocol challenge (`WWW-Authenticate: Payment`, method `stripe`). An agent with a Link wallet or a Stripe Shared Payment Token pays it, for example with `npx @stripe/link-cli mpp pay <url>`, and retries with `Authorization: Payment`. If the tool then fails, the card payment is refunded.− - [Listing lint](https://api.agoranome.com/v1/seller/lint): $0.005 per call, GET with a query string. Inputs: url (string, required). Why isn't my x402 API in the Bazaar? Listing lint checks an x402 endpoint for Bazaar indexing: one unpaid call validates its 402 PAYMENT-REQUIRED header, discovery metadata, input and output schemas, description limits and service name against the indexing rules, with a fix for each problem. Use when an agent needs to lint an x402 listing before its first settled − - [Rank check](https://api.agoranome.com/v1/seller/rank): $0.01 per call, GET with a query string. Inputs: task (string, required), resource (string, required), network (string). Where does my x402 API rank in Bazaar search? Rank check runs the search a buyer agent would run for your task and returns your rank, the competitor listings ahead of you, and the signals where you trail them (payers, calls, description, output example, schema, price). Search rank, SEO and competitor analysis for x402 l− - [Machine Buyer Panel](https://api.agoranome.com/v1/seller/panel): $1.00 per call, POST with a JSON body. Inputs: resource (string, required), tasks (list of string, required). Will buyer agents choose my x402 API? The Machine Buyer Panel is an A/B conversion test: buyer-agent models choose between your offer and its real Bazaar rivals for up to three tasks, across buyer personas and list positions. Returns your win rate with confidence intervals, why you lost, and up to three truthful edits te− - [Demand gap finder](https://api.agoranome.com/v1/seller/gaps): $1.00 per call, GET with a query string. Inputs: topic (string). What x402 API should I build? The demand gap finder runs up to 150 Bazaar searches phrased the way buyer agents phrase tasks and ranks the unmet demand: tasks whose top results are weak (no listings, few payers, thin descriptions or a poor fit), with the evidence for each. Public Bazaar data only, joined with measured repeat demand per category.− - [Payment test](https://api.agoranome.com/v1/machine/ping): $0.001 per call, GET. Inputs: no inputs. x402 ping and test payment: can my wallet pay an x402 API? Pay a fraction of a cent in USDC on Base and get a signed receipt back, proof that your wallet and x402 client complete a real paid call end to end. Use when an agent needs a cheap test payment endpoint before buying anything bigger.− - [Listing report cards](https://api.agoranome.com/sellers): How each Bazaar seller's listings look to a buyer agent's search, graded, from the weekly index snapshot. JSON at /sellers/{host}.json. Free.− - [MCP server](https://api.agoranome.com/mcp): Streamable HTTP. The same tools (lint_listing, rank_check, buyer_panel, signed_sample, demand_gaps, payer_analytics, weekly_insights, ping) plus a free rank_sample. A paid tool answers an unpaid call with an error result whose structuredContent is the x402 PaymentRequired; retry with the payment payload in params._meta["x402/payment"]. The settlement comes back in _meta["x402/payment-response"].− - [Catalog](https://api.agoranome.com/v1/catalog): every offer as JSON, with input schemas and examples.− - [Agent manifest](https://api.agoranome.com/.well-known/agent-manifest): the same, as an agent card.+ > Tools for x402 sellers and buyers, paid per call in USDC by the agents that use them. For sellers: a listing lint and a 402 conformance run, a Bazaar rank check, a Machine Buyer Panel that tests whether buyer agents pick your offer over its rivals, signed samples, Fair Offer certification, a model-update watch, and a demand gap finder for what to build next.

A call that fails isn't settled.+ - Skyfire: over MCP, send a Skyfire `pay` or `kya-pay` token in the `kyapay-token` header, made for Agoranome's Skyfire service `df5f38aa-f32a-4d21-9d71-bd9bb82ea72a`, and the tool charges its price to it.+ Agoranome has no token or coin.
