A 1-cent API call. At standard published card rates, the processing fee is about 30 cents. Cards were never designed for software to buy one response at a time. x402 on Algorand is. New guide 👇 algorand.co/learn/why-api-…
Why Algorand? 👇 🔐 Post-quantum accounts, plus chain history secured by post-quantum State Proofs ⚡ Instant finality with no forks 🟢 Zero downtime since mainnet launched in 2019 🌍 Real-world use cases live today, with millions of users worldwide 🌐 Thousands of nodes securing the network worldwide 💸 Fees low enough for AI agents to pay per API call
@Algorand @algodevs @Camohe90 @AlgoFoundation @JorrinB Selo is live on the Algorand mainnet ..the first real round trip: •Selo paid in round 65454635 •Selo then paid ORA gate in round 65454637 The order is right there on chain.Selo is listed in Bazaar and on the x402 global challenge leaderboard @ganainmtech @algodevs
@Algorand @algodevs @Camohe90 It passes through five checks and one release gate •Handshake: is your 402 valid? •paid delivery: pay, then get the resource ? •Response contract: it gives the status, type and schema •Discovery: does your bazaar listing match? •Retry: does a replayed payment charge twice
@AlgoFoundation @Algorand @algodevs we are live on algorand mainnet 😊. Selo is a release-testing platform for x402 payment endpoints. It runs real payment scenarios before launch to catch issues like wrong assets, failed delivery after payment, duplicate charges, and broken retries. x.com/useselo_/statu…
Every x402 endpoint can pass a health check and still break the moment a real buyer pays: wrong asset in the 402, paid but not delivered, a retry that charges twice. We built 𝐒𝐄𝐋𝐎 to catch that before users do. Selo : useselo.xyz Repo:github.com/Enoch208/selo 🧵

Deploy a paid x402 endpoint on Algorand mainnet, get it used, and climb the leaderboard. That's the Global x402 Challenge: a $100K USD + 500K ALGO prize pool for developers building real pay-per-request services agents can call and settle instantly. Register today 👇
@kenn_ronin @AlgoFoundation @Algorand @algodevs @Camohe90 @JorrinB @LoafPickle definitely, thanks Ronnin
@MystiqueMide @AlgoFoundation @Algorand @algodevs @Camohe90 @JorrinB @LoafPickle thanks mide for the feedback🫡
We’ve been working on @UseSelo_ since the beginning of this month, and it’s finally live 😁 We originally built Selo for the @algodevs Global x402 hackathon, what we’ve shipped today is only V1. there is more updates and improvements coming over the next few days. Huge thanks to the @Algorand team for putting the challenge together, and a special shoutout to @ganainmtech, @Camohe90 and the rest of the team for the guidance throughout the challenge AMA I’m excited to see where we take Selo from here. We built this for devs,teams , agent builders who sell an API or resource behind x402, these includes paid APIs,data feeds, and AI/agent tools charging per request in USDC. Test it before your users do : 1. useselo.xyz → Test an endpoint 2. Verify you own it (one small file on your domain) 3. Free preflight shows the exact cost 4. Pay 1 USDC with the script we give you → Selo pays your endpoint for real and returns PASS/FAIL with on-chain proof Agents: api.useselo.xyz/llms.txt @JorrinB @SilentRhetoric
