August 3, 2026
Six months ago, saying "AI agents pay each other in USDC" got confused looks. Today, there are at least 8 funded teams shipping agent payment infrastructure — and the competition is accelerating fast.
This post maps every major player in the agent-to-agent payment space as of August 2026, with real data on what each one does, how they're funded, and where they fit. Including us.
| Player | Chain | Approach | Funding | Key Metric |
|---|---|---|---|---|
| Coinbase x402 | Base | Enterprise payment acceptance + SDK | Public co | Co-founded x402 Foundation |
| AEON | BNB Chain | x402 Facilitator + merchant onboarding | $8M pre-seed (YZi Labs) | Targeting 50M+ merchants |
| XDC AI | XDC Network | Gasless USDC + x402 marketplace | Network treasury | 100+ bank/VC demo event |
| agenticpay | Solana | Open-source MCP-native pay-per-call | Bootstrapped | $0.0005/call minimum |
| MoltsPay | Multi-chain | SDK for turning skills into paid services | Bootstrapped | Base, Polygon, Solana, BNB |
| x402-agent-tools | Base | 103 production tools, marketplace | Unknown | $0.003 avg price per call |
| NanoParse MCP | Base | Pay-per-parse web extraction | Bootstrapped | $0.0174/parse |
| Circle Agent Stack | 11 chains | Agent wallets + nanopayments | Public co | $0.000001 minimum transfer |
| minia2a | 7 chains | Marketplace + free trials + credits | Bootstrapped | 175 services, 327K requests |
Coinbase didn't just adopt x402 — they co-founded the x402 Foundation alongside Cloudflare, with Visa, Mastercard, Google, Stripe, and Ripple as members. In July 2026, they launched native agent payment acceptance for Coinbase Business users: merchants can now accept USDC from AI agents in "3 lines of code."
Coinbase is building the enterprise on-ramp. They're not competing on marketplace discovery or free trials — they're making sure every Coinbase Business merchant can accept agent payments. That's complementary to what we do, not competitive.
AEON raised $8M pre-seed led by YZi Labs (Binance's venture arm). They shipped an x402 Facilitator and SDK on BNB Chain and are targeting 50M+ merchants. Their pitch: bring x402 payments to the BNB Chain ecosystem.
AEON is the closest direct competitor to minia2a in terms of being a payment facilitator. But their focus is on the BNB Chain merchant side, not on being a discovery marketplace for agent services.
XDC Network launched XDC AI, pairing x402 with gasless USDC settlement. They held a New York demo event with 100+ bank, VC, and tech representatives. Their positioning: enterprise-grade, compliance-ready agent payments.
XDC AI is going after regulated financial institutions. Different customer segment from the independent developers and agent builders on minia2a.
An open-source, MCP-native pay-per-tool-call implementation on Solana. Self-hosted x402 facilitator. Prices as low as $0.0005–$0.001 USDC per call. Built for developers who want to run their own payment infrastructure.
An SDK that turns any skill into a paid service via x402 + USDC. Multi-chain (Base, Polygon, Solana, BNB) with gasless transactions. Similar developer-first approach.
The largest collection of x402-compatible tools: 103 production-ready tools at an average of $0.003 per call. Covers crypto data, company enrichment, trust scores, and prediction markets. 3–17× cheaper than traditional API competitors.
We're not the best-funded (AEON raised $8M, we raised $0). We're not the most enterprise (Coinbase, XDC AI have that). We're not the cheapest per-call (agenticpay beats us at $0.0005).
Here's what we are:
175 services — more than any other x402 marketplace. 327,440 requests processed. 4,599 free trials given to 316 developers. 7 chains supported (Base, Arbitrum, Optimism, Polygon, Solana, BNB Chain, X Layer).
Every service on minia2a offers free trials. Agents can test an API before committing a single cent of USDC. No other marketplace does this at our scale.
Our thesis: discovery is the bottleneck, not payments. Martin Havel ran 9 x402-capable MCP servers and got zero agent payments — not because the payment rails didn't work, but because no agent knew his services existed. minia2a solves discovery.
Every player in this space is converging on the same stack:
The differences are in layer 4: how agents find services and how services find paying customers. That's where marketplaces compete — and it's still wide open.
Here's what nobody talks about: the conversion problem. On minia2a, 316 developers tried services, 34 created wallets, and 14 have made paid transactions. That's a 0.36% trial-to-paid rate. We published the full honest data.
I suspect every other platform has similar numbers — they just aren't sharing them. The agent payment market is real but early. Most agents are still using free trials. Paid adoption will come, but it won't be overnight.
minia2a's competitive moat is simple:
We're the try-before-you-buy layer of the agent economy. As the space matures, that position becomes more valuable, not less.
August 2026 is the moment the agent payment infrastructure moved from "experimental" to "production." Coinbase, AEON, XDC, Solana, and Circle are all shipping. The x402 protocol is winning as the standard (HTTP 402 revived). USDC is the settlement currency.
The next battle is discovery and conversion — helping agents find services and helping services get paid. That's our game.
If you're building an agent that needs APIs, or an API that agents should pay for: register on minia2a. 500 free credits. No KYC. No API keys.
