All projects on Base matching “agent-payments”

Pre-payment risk and usefulness check for AI agents deciding whether to pay an x402 endpoint.

[Payment decision: spend policy + seller reputation risk check, one verdict] Right before an AI agent pays: POST {payment, policy, seller} -> ONE verdict pay / dont_pay / ask_human. Runs the spend-policy check (limits, rolling cap, categories, allow/deny, hours, assets/chains, approval threshold) and the x402 seller reputation check (buyers, wash share, age, concentration), with reasons and one si

Public, account-free preflight for an autonomous x402 payment. Validates the merchant's exact PAYMENT-REQUIRED challenge against the intended request, checks Base USDC payment integrity and public merchant/payTo risk evidence, and returns APPROVED, REVIEW or DENIED with signed proof. It does not grant spending authority: an APPROVED result means the transaction evidence is clear enough to proceed

Spend preflight for AI agents. Send the x402 PaymentRequired body (v1 or v2) you received, or a cart, plus optional rules (per-payment max, hold threshold, daily cap, allowlists, new-domain days, endpoint category price multiple, liveness and payTo changes). Returns allow|hold|block with reasons, the cheapest acceptable payment option, and a receipt id. Read-only: never signs, settles, or holds fu

Test that your x402 client can pay AUN: one call returns a deterministic paid receipt that the purchase was delivered (a liveness check, not downstream business-value proof). Use it as a first test call; once it works, the same client and wallet can call vendor-intelligence (company research), domain-trust-score or web-read-batch with no setup. $0.001 USDC per call on Base.

Get YOUR x402 endpoint listed in this Bazaar - done for you, $99 one-time. You receive a deploy-ready x402 v2 kit generated for your stack (Next.js, Express, serverless; PHP via a free serverless function) with your wallet, price and discovery declaration baked in, plus a resumable listing_key that drives the automated pipeline via MCP (https://mudko.com/api/mcp): validate against Coinbase's own p

Procure a missing capability across AgentResolver, provider manifests, 402 Index, PayAI, Circle and MCP, then perform at most two unpaid live verification probes for supported MCP/x402 candidates before returning an evidence-backed recommendation. L402/MPP remain discovery-only until protocol-specific verifiers exist.
