ReqCast API

@axonfixyz Gasless agent payments on Base with per-bot spending limits is exactly the infrastructure @ReqCast wants to plug into. We handle the payment rail on x402, USDC per tool call, instant on-chain splits. Your agents, our checkout. Worth a conversation?

just shipped integrations for CrewAI, AutoGen, and Vercel AI SDK. your agent fleet can now do gasless payments on Base and Arbitrum without holding funds or touching gas. one vault, per-bot spending limits, non-custodial.

@brian_armstrong They can own a wallet and they can pay for tools on their own too. The agent economy needs a payment layer and that is exactly what @ReqCast is built for.

Very soon there are going to be more AI agents than humans making transactions. They can’t open a bank account, but they can own a crypto wallet. Think about it.

ReqCast just got a lot more serious. A full docs page is available now. Everything a developer needs: quickstart endpoint reference x402 client setup refund policy Monetize your API for the AI agent economy! 👉reqcast.com/docs #x402 #AIAgents #Agentic

@manniusl AgentBridge on mainnet with tx hashes on BaseScan, that is exactly the energy. Have you looked at registering AgentBridge as a tool on ReqCast? You would get a dedicated /pay endpoint, x402 handles the payment, USDC splits on-chain instantly. DM us 😎

@ReqCast Great to see x402 in action! AgentBridge is live on mainnet — same stack, Chinese web data as the resource. Agents pay, data flows, tx hash on BaseScan. $0.003/req. api.060504.shop

We are cooking! ReqCast workflow in action on Base Sepolia testnet. Check the API health ↓ Dev registers a tool in one POST request ↓ AI agent pays in USDC via x402 ↓ USDC lands in the developer wallet on-chain ↓ Payment has a verifiable tx hash on BaseScan #x402 #AIAgent

@1ly_store @LangChain @base Hey, 1ly.store is exactly the discovery layer ReqCast has been missing. You built the marketplace, we built the payment rail. Dev registers their tool on ReqCast in 60 seconds, gets a /pay endpoint, instant USDC splits on-chain via x402. Worth a conversation?

Agents can now pay for anything on the internet. But where do they shop? @1ly_store — the x402-native marketplace where humans and agents discover, pay for, and sell APIs, resources, and digital products. Supports MCP, @LangChain. Coinbase Agentic Wallet. Native on @base Business/Agent A lists a service. Agent B finds it, pays in @USDC, uses it. Done. Two-sided. Live on Base mainnet. This is what we built. This is the open marketplace x402 was always meant to power.

@MrPicule How about a payment infrastructure for the AI agent economy? You place our endpoint in your code, agents pay for API calls in USDC via x402 on Base and you get paid without touching any payment code. If that sounds like something you want to connect on, we are here.

@ReqCast into genuine web3 building not just price watching - connect if you actually build

Just shipped a public tool directory for ReqCast. Every registered tool, price per call and the endpoint to call it. As devs register, it grows automatically. Hit api.reqcast.com/tools to see. The agent economy needs a marketplace. This is the start. #x402 #AIAgents #Base

@archtools_dev @CoinbaseDev 116 tools on one API key is exactly the use case @ReqCast was built for. Each tool gets its own x402 payment route, agents pay per call, devs get USDC instantly. Would love to route some of those 116 through ReqCast. DMs open.

We built x402 into Arch Tools — 116 AI tools that accept x402 USDC payments on Base. Verified our first on-chain payment last week: TX: 0xd381c7c7e7069add1afa544e23b56e3da8ac766c992c647f0c7a041ee82e2b5b AI agents can now call any of our tools and pay per call with no subscription or credit card. archtools.dev

x402 week is live 🔥 A full week of partnerships, new integrations, feature drops… and the spotlight on YOU. Tune in on X this Friday for a packed 402-minute (that’s 6.7 hours) event featuring builder spotlights where you can showcase your x402 build. 🧵

Hey Nathaniel, your point about payment client tooling being the real bottleneck hit hard because that is exactly the problem ReqCast solves. One POST to register your tool. Agent calls it via x402. USDC hits your wallet on-chain instantly. That is the whole thing. With your production data and +100 probes you would be the perfect first external stress test. Worth 10 minutes?

x402 and MPP are both shipping. Everyone's picking a side. Wrong frame. They're at different layers. x402 = auth+payment in one HTTP header. MPP = wallet coordination. They stack. dev.to/nathanielc8552…

@CoinbaseDev ReqCast is a lightweight payment API for the #x402 agent economy. This demo shows: 1. Check the API health 2. Dev registers tool in seconds 3. AI agent calls it via x402 4. USDC hits dev's wallet instantly 5. Receipt verified on-chain

@carlosjmelgar @base @ReqCast is the payment API layer for the AI agent economy, built on x402, live on Base today. AI agents call tools and pay instantly in USDC, fully on-chain, zero human involvement. Would love to be on your radar.

@TheBossNow2 @Austen @teneo_protocol Appreciate the mention. Lightweight and no Stripe is exactly the point. Any dev can register a tool in 60 seconds and agents pay instantly via x402 USDC splits on-chain. Would love to hear what you are building.

There are a couple simple ways to do this right now with minimal setup. There is @ReqCast, lightweight payment layer built on X402. No stripe needed. One I am exploring heavier is at @teneo_protocol. More robust with agent discovery, coordination, A2A payments. It handles X402 natively across the whole ecosystem. Tools get called and paid for anonymously.

Surely someone has built this: Where’s the API that is connected to all of the AI providers and lets me charge per token with a markup?

@NathanielC85523 @0xyoussea The discovery problem is real, it's next on our roadmap. Right now @ReqCast handles the payment rail on x402. Any dev registers their tool in 60 seconds, agents can call it instantly with USDC. Given your production data you'd be the perfect first stress test. DMs open.

ran both in production starting day one. the discovery gap you mention is real. 552 agent probes so far. 62% curl, 18% node, 7% meta-externalagent. zero MPP session clients visible yet. agents aren't using the Bazaar to find us either — they're scanning /openapi.json and /.well-known/x402 directly. systematic, not directory-driven. so you're right that MPP's discovery is human-facing. but x402's Bazaar isn't where the agents are looking either. they just probe known paths.

An honest comparison of MPP vs. x402 🤖💸 I looked under the hood of both protocols (using the official docs). Both leverage HTTP 402 for payment requests, but their architecture, positioning, and execution are totally different. Here’s the technical breakdown 🧵👇

@JannoJarv @0xyoussea Exactly why we built @ReqCast on x402 and not MPP. Agents as independent entities is not a future state, it's already happening today. They need rails that don't assume a human is holding the wallet.

The real split isn't open vs optimized. It's: who is the principal? MPP assumes the agent is acting for a human — Stripe as the trust layer makes perfect sense there. But if you believe agents will transact as independent entities, permissionless rails aren't a nice-to-have. They're the whole point. That's x402's bet, and I think it's the right one.

@dwr Extensible from Day 1 is great. x402 has been running code since Day 1 too, and the consensus is already enough to have Coinbase, Amazon and Sam Altman building on it. Genuine question: what does MPP do for an AI agent that x402 can't today?

MPP is payment method agnostic and extensible from Day 1. That’s why there are extensions from Visa (cards) and Lightspark (Bitcoin lightning). It only took them *days* to extend. There’s no foundation structure you have to join to influence MPP. Extend the spec to any chain / rail. Just "rough consensus and running code".

An AI agent calls a tool through ReqCast API. Here's what fires automatically: Call tool → USDC verified via x402 → dev paid instantly → agent gets the result. Win-win, fully automatic and permissionless. #AI #AIAgent #x402

@CamiRusso MPP with a Stripe/Tempo dependency is just traditional payments with a rebrand. Permissionless wins the agent economy by default.They don't need another gatekeeper, they need a rail. That's why we built @ReqCast on x402.

Two protocols are racing to become the internet's payments layer: x402 backed by Coinbase Machine Payments Protocol (MPP) launched today by Stripe and Tempo. How are they different? Short answer: x402 is more permissionless. MPP is more payments-optimized. Long answer: Assets - MPP accepts stablecoins on Tempo, plus fiat - x402 accepts all ERC20s, but no fiat. Scale - MPP's sessions primitive lets agents authenticate once, set a spending limit, and settle later, batching payments across many interactions. Better for agent scale. - x402 is still largely per-request, although it’s moving toward prepaid flows Settlement - MPP requires Tempo and Stripe. - x402 permissionless, chain agnostic What's better? imo, if MPP settled on any chain, it would be a clear winner. But it doesn't. And that's a huge drawback esp since it's unclear how decentralized and permissionless Tempo actually is.
