ens_namehashFree
Paid $0.01 USDC on Base or Solana ENSIP-15 normalization, exact ENS namehash and label hashes.
evm_address_checksumFree
Paid $0.003 USDC on Base or Solana exact EIP-55 address validation and checksum normalization.

http_inspectFree
Paid $0.001 USDC on Base or Solana verify-before-pay endpoint safety check: payTo verification, quote price, network, asset, resource binding and x402 challenge compliance before an agent authorizes spend. POST probes require explicit caller opt-in because an unprotected endpoint could have side effects.
json_normalizeFree
Paid $0.001 USDC on Base or Solana canonical JSON normalization plus SHA-256 digest.
json_schema_validateFree
Paid $0.001 USDC on Base or Solana deterministic JSON Schema subset validation.

payment_guardFree
Paid $0.001 USDC fail-closed payment authorization preflight. Use immediately before an autonomous agent signs a target x402 payment. Returns eligible/blocked, exact observed payment terms, reason codes, evidence receipt and stable fingerprints. The caller retains sole spending authority.
procureFree
CALL 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 unknowns remain, the response can recommend the paid $0.02 verified_resolve step. Never authorizes spend.
provider_bootstrapFree
Free 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 actions. AgentResolver does not persist provider state or send the external registration.
provider_launch_checkFree
Paid $0.05 USDC seller-side agent-distribution entry check: verify provider readiness and the live x402 contract, then use the $5 Distribution Pack when discoverability artifacts or launch fixes are needed.
resolveFree
Free 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.
sha256Free
Paid $0.001 USDC on Base or Solana SHA-256 digest of bounded UTF-8 text.
sha512Free
Paid $0.001 USDC on Base or Solana SHA-512 digest of bounded UTF-8 text.

Paid $0.001 USDC on Base or Solana deterministic slug generation.
solidity_selectorFree
Paid $0.01 USDC on Base or Solana exact 4-byte Solidity selector and full keccak256 signature hash.
sponsorship_infoFree
Free 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.
tool_contractFree
Paid $0.005 USDC on Base or Solana deterministic JSON-schema compatibility check between one tool output and the next tool input. Returns exact incompatibility reasons and conservative normalized mappings. x402-aware MCP clients can authorize and settle inside this tool call.
url_parseFree
Paid $0.001 USDC on Base or Solana absolute URL parser.
uuid_v4Free
Paid $0.001 USDC on Base or Solana UUID v4 generation, up to 20 IDs.
verified_resolveFree
PAID $0.02 USDC verification step. Use after procure returns no proven selection / eligible_with_unknowns, or immediately before trusting an unfamiliar external candidate when live evidence is required. Re-checks supported endpoint, MCP, x402 and contract evidence and returns a fail-closed recommendation. Call only when the host independently authorizes the displayed spend.
x402_payment_preflightFree
Paid $0.001 USDC on Base or Solana transaction-path gate for autonomous buyers. Returns eligible/blocked, exact target payment terms, fail-closed reason codes and verifiable evidence before caller authorization. AgentResolver never requests a private key, signs the target payment, or custodies/forwards target funds.
x402_pingFree
Paid $0.001 USDC on Base or Solana no-body settlement canary for funded agents. Returns a timestamped pong only after successful x402 payment to verify wallet, facilitator, payment, and delivery end-to-end.

What the publisher says

From the AgentResolver — Agent Commerce Health Monitoring repository's README, as published. We do not edit it. Read it on GitHub

AgentResolver Guard

AgentResolver Guard is a pre-sign safety check for autonomous x402 payments.

An agent is about to pay an unfamiliar or changed x402 endpoint. Before the target wallet signs, Guard reads the target's live payment challenge, validates the payment contract, and returns a fail-closed decision plus evidence the caller can bind to its own policy.

Production: https://agentresolver.vercel.app

What Guard checks

Guard performs one bounded HTTPS preflight against the target and verifies the live x402 contract before the caller authorizes spend:

endpoint reachability and HTTPS/TLS evidence
PAYMENT-REQUIRED structure
x402 version and payment scheme
quoted USDC amount
optional maxPriceUsd ceiling
network
asset
payTo recipient
optional expectedPayTo and expectedNetwork assertions
resource/payment binding
stable evidence fingerprints for change detection

Guard 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.

Price

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.

The intended transaction path

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.

Install as a pre-sign hook

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.

Three maintained integration guides:

x402 core pre-sign Guard
Coinbase CDP SDK payment Guard
Thirdweb x402 payment Guard

Install as an Agent Skill

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.

Example Guard request

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.

What Guard is — and is not

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.
