Description from the maker (original English)
Free API/MCP/x402 health checks plus $19 hourly managed monitoring for agent services.
These three are never merged into one score: opinions, measurements and popularity are different things.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.
Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.
sponsorship_infoFree read-only information for tool/API/MCP providers about AgentResolver's explicitly labeled sponsorship pilot. Organic ranking remains independent; applying creates no purchase or financial commitment.
resolveFree exploratory discovery. Use only when browsing possible tools/APIs/MCP services without needing a trustworthy execution choice yet. For an actual missing capability, prefer procure so required evidence fails closed and unresolved candidates can escalate to verification.
provider_bootstrapFree zero-state provider onboarding. Reads the fixed AgentResolver well-known manifest on one HTTPS origin, live-verifies selected same-origin x402 payment identities, returns an immediate providerOrigins procurement seed, and prepares caller-owned durable 402 Index registration
procureCALL THIS when the agent's installed tools do not clearly satisfy the current task. Free open-world procurement across APIs, MCP, x402, L402 and MPP. Required compatibility evidence fails closed: AgentResolver returns no selected provider rather than guessing. When supported unkn

Continuous API, MCP, and x402 compatibility monitoring for services used by AI agents.
AgentResolver answers a production question ordinary uptime monitors miss: can an AI agent still discover, call, and pay this service right now?
Production: https://agentresolver.vercel.app Free browser check: https://agentresolver.vercel.app/monitor
Start with the free public-service snapshot at GET or POST /api/service-monitor. It checks machine-facing discovery and can optionally run a real MCP initialize + tools/list exchange and a GET-safe x402 payment-contract inspection for same-origin public endpoints.
When an operator wants AgentResolver to own the schedule, POST /api/managed-monitor-30d is $19 USDC for 30 days of recurring monitoring that targets an hourly cadence with a durable public status record. Managed monitoring stores public target URLs and health snapshots only; it does not store wallet keys, API credentials, or customer contact information.
Existing x402 resource servers can route their standard facilitator traffic through AgentResolver without changing the merchant payTo address:
import { HTTPFacilitatorClient } from "@x402/core/server";
const facilitator = new HTTPFacilitatorClient({ url: "https://agentresolver.vercel.app", timeoutMs: 10_000 });
Standard facilitator surface:
GET /supported
POST /verify POST /settle
Verification is read-only and may use an explicitly configured secondary. Settlement is submitted to exactly one upstream facilitator; ambiguous timeout/5xx outcomes are marked non-retry-safe instead of being blindly failed over. Full integration guide: x402 Reliability Router.
Run the public-service check on your own GitHub schedule. No AgentResolver account, API key, wallet, or secret is required.

The free Action reports current machine-readiness, optional live MCP initialize + tools/list compatibility, and optional GET-safe x402 payment-contract health. The hosted managed monitor is the $19 / 30-day option when you want AgentResolver to own the recurring schedule and durable status.
Full setup: free GitHub monitoring.
AgentResolver Guard remains the pre-sign safety check for autonomous x402 payments. Before a target wallet signs, Guard reads the live payment challenge, validates the payment contract, and returns a fail-closed decision plus evidence the caller can bind to its own policy.
Guard performs one bounded HTTPS preflight against the target and verifies the live x402 contract before the caller authorizes spend:
PAYMENT-REQUIRED structuremaxPriceUsd ceilingpayTo recipientexpectedPayTo and expectedNetwork assertionsGuard blocks private/reserved network targets, does not follow redirects, uses bounded timeouts, and fails closed when required evidence is missing or mismatched.
Guard never receives the target-payment private key, signs the target payment, authorizes the target spend, or custodies/forwards target funds. The calling runtime keeps spending authority.
Canonical Guard:
POST or GET https://agentresolver.vercel.app/api/x402-payment-preflight
$0.001 USDC per successful Guard check Base or Solana where advertised
The compatibility alias /api/payment-guard uses the same Guard product. A Coinbase-CDP-specific Base route is available at /api/cdp-payment-guard for $0.002 USDC because that rail has a higher observed settlement floor.
target request
-> target returns 402 -> AgentResolver Guard -> validate amount / asset / network / payTo / scheme / resource binding -> Guard returns eligible or blocked + evidence -> caller policy decides -> caller-owned wallet may sign the target payment
Guard is evidence for a payment decision, not permission to spend.
The official x402 client exposes onBeforePaymentCreation. Use two x402 clients: one hooked client for the target payment and one hook-free client dedicated to the separate Guard payment. This prevents recursive Guard payments.
The framework-neutral client package now exports the reusable pre-sign hook directly:
import { createAgentResolverX402GuardHook } from "agentresolver-client";
targetClient.onBeforePaymentCreation( createAgentResolverX402GuardHook({ maxTargetPriceUsd: 0.05, guardFetch // separate payment-enabled fetch used only for the Guard fee }) );
Until registry publication, build packages/agentresolver-client directly from this repository. The hook fails closed and binds AgentResolver evidence back to the exact selected scheme, network, asset, amount, payee, x402 version, and resource before the x402 client can proceed to signing.
Three maintained integration guides:
npx skills add waxsway/agentresolver --skill agentresolver-payment-guard
Direct skill source:
https://agentresolver.vercel.app/.well-known/agent-skills/agentresolver-payment-guard/SKILL.md
The skill tells a wallet-capable agent to run Guard before each unfamiliar or changed autonomous x402 spend.
Guard supports a target URL plus optional caller assertions:
{
"url": "https://target.example/api", "method": "GET", "maxPriceUsd": 1.00, "expectedPayTo": "0x...", "expectedNetwork": "eip155:8453" }
The unpaid request returns AgentResolver's own x402 challenge. After the caller authorizes and settles the Guard fee, the response contains the observed target-payment terms, reason codes, eligibility decision, and evidence receipt.
Guard is a transaction-path control for x402 buyers. It is designed to answer a narrow question immediately before signing:
Does the live payment challenge still match the payment contract my agent is willing to authorize?
Guard does not claim that a provider is honest, that a wallet has a particular legal owner, or that future fulfillment is guaranteed. It validates live payment-contract evidence and caller-supplied policy assertions.
Wallet-risk, reputation, AML, and other third-party evidence can be added later through explicit evidence-provider interfaces if real users require them. They are not bundled into Guard by default.
AgentResolver still exposes supporting infrastructure used by integrations, testing, and open-world fallback workflows. These surfaces are not the primary product:
procure / resolve capability discoveryhttps://agentresolver.vercel.app/mcp/controlNew utility endpoints, passive directory submissions, and speculative marketplace-specific builds are not product strategy. Agent Commerce Health monitoring is the primary commercial product; Guard and the reliability router remain supporting buyer-side/payment infrastructure.
