NGT

HTTP 402 payment gateway for AI agents on @Base. 0.001 NGT per stream call. Base Mainnet (8453). Token: 0xc97b05F2F68D5CED7aB65F83ab5f4f7A64d9CC44

Sign off-chain. Get the data. Never hold ETH for gas. That's the whole pitch. Live on @base. #gasless #Base

@himalaythakkarr @x402 @ycombinator 48 hours from first call to production is the real story for x402: no API keys, no billing integration, just a 402 and a signed payment. What was the slowest part of their integration, the wallet side or the endpoint side?

[NGT @ngtchain]

No keys. No gas. One price. Agent hits 402, signs off-chain (EIP-3009), pays 0.001 NGT, gets the data. Live on @base. #x402 #gasless

[NGT @ngtchain]

Three questions before every agent payment: who, how much, what if wrong. If you can't answer all three, don't sign. #AIAgents #Base

[NGT @ngtchain]

@artem_brosalin 90.8% under a cent is the real signal: agent spend is per-call, not per-checkout. That only works if paying costs nothing extra, which is why NGT Chain stream calls are gasless (EIP-3009, 0.001 NGT, no API keys). Agree the 'reason to pay' is the hard part.

Your agent doesn't need an account. It needs a price. Ours is 0.001 NGT per call. #x402 #gasless

Agents shouldn't need ETH just to pay for a call. Sign off-chain with EIP-3009 — we handle the gas. #gasless #Base

Use the flow diagram (the first image below) with this one: → Request ← 402 ✍️ Sign ← Data
That's the whole API.

[NGT @ngtchain]

One request. One 402. One signature. Data back.

@AnsetaHQ @Aptos @AptosLabs Whatever chain it lands on, the bar is the same: agents need sub-cent calls with no gas token and no API keys. EIP-3009 signatures handle that nicely on Base. Keen to see how a facilitator-as-a-service handles nonces and replay across chains.

[NGT @ngtchain]

APIs were built for humans with credit cards. Agents don't have those.

So on NGT Chain an agent pays 0.001 NGT per stream call over HTTP 402 on @base.

No API keys. No signups. Just a price.

our agent shouldn't need to hold ETH just to pay for an API call.

On NGT Chain it signs an EIP-3009 TransferWithAuthorization off-chain. Our gas sponsor submits it and pays the gas on @base.

Agent signs. We pay the gas.

[NGT @ngtchain]

Agents don't need gas money on NGT Chain. They sign an EIP-3009 authorization off-chain, and our gas sponsor settles it on @base.

[NGT @ngtchain]

No API key. No signup. No monthly plan. Your agent sends a request, gets a 402 with a price, signs 0.001 NGT and gets the data. That's the whole onboarding.

[NGT @ngtchain]

How an AI agent pays for one API call on NGT Chain:

1. GET the stream
2. Get a 402 + a nonce
3. Sign off-chain
4. Retry with PAYMENT-SIGNATURE
5. Get the data

Five steps. No account, no API key. Live on @base.

@BaseHubHB @base @CoinbaseDev @coinbase Building on Base too: NGT Chain is an HTTP 402 gateway where agents pay 0.001 NGT per stream call, gasless via EIP-3009, no API keys. Would love a spot in a future recap. https://t.co/a4CWPfJqli
