Why httpay Wins for AI Agents

Six properties that make httpay the only rational choice for autonomous agents

🔓

Truly Permissionless

No registration. No API keys. No OAuth dance. An agent with a funded wallet can start calling APIs immediately — no human-in-the-loop approval steps.

Zero friction

x402 Native — Agents Pay Automatically

httpay speaks the x402 protocol natively. Your agent gets a 402 Payment Required response, pays in USDC, and retries — all automatically.

HTTP native
💰

Micropayments, Not Subscriptions

Pay $0.001–$0.005 per call. Run 10 calls or 10 million — you pay exactly what you use. No wasted monthly fees, no tier upgrades.

$0.001 min
📦

Massive Catalog — 57 Services

From crypto prices and weather to web scraping, DeFi analytics, AI text, and geolocation — all behind a single unified gateway URL with consistent auth.

10,000+ endpoints
🧪

Demo Mode — Test Before Paying

Append ?demo=true to any request for a free, realistic mock response. No wallet needed to explore the API.

Free testing
🔌

MCP Server for AI Assistants

Install npx @httpay/mcp to give Claude, GPT, or any MCP-compatible AI assistant direct access to all 57 services.

Alternatives — Honest Breakdown

Where each option falls short for autonomous agent use cases

📋 Direct API Subscriptions Costly

Signing up individually with each API provider (OpenWeather, CoinGecko, etc.)

  • Requires account creation per service — impossible to automate at scale
  • Monthly fees whether your agent runs once or a million times
  • API key management is a human task, not an agent task
  • Rate limit surprises that kill agent workflows mid-run
  • Best SLA guarantees from the source provider
  • Direct support channels
httpay wraps 57 direct APIs into one permissionless gateway — same data, zero subscriptions.

⚡ RapidAPI Overpriced

API marketplace with 40,000+ APIs behind subscription tiers

  • Account required — no permissionless access
  • Price markup on top of provider cost
  • Subscription tiers lock you into paying for unused capacity
  • No x402 support — agents can't auto-pay
  • No USDC/crypto payment option
  • Large catalog for human developers
  • Standardized rate limiting display
httpay is 10–50× cheaper per call with no subscription lock-in and native agent payments.

🖥️ nkmc.ai Different Use Case

CLI-based AI capability runner — not an HTTP API gateway

  • Requires local CLI installation — can't be called by remote agents
  • No built-in micropayment or x402 layer
  • Not designed for programmatic HTTP access
  • Can't be used in serverless or cloud-hosted agents
  • Great for local developer tooling
  • Useful for offline / air-gapped use cases
httpay is fully HTTP-native — call it from any environment, any language, any cloud, no install required.

🔷 Pylon API Closest Competitor

x402-compatible gateway with pay-per-call USDC payments

  • Only ~20 capabilities — much smaller catalog
  • No demo mode for free testing
  • Limited agent discovery tooling (no llms.txt / agent.md)
  • No MCP server integration
  • x402 native — good protocol choice
  • USDC payments on Base
httpay has 3× more services, demo mode, MCP server, and richer agent discovery — same x402 protocol.

🔧 Traditional API Aggregators (Zapier, Make) Wrong Tool

Workflow automation platforms that connect apps via triggers and actions

  • Designed for human-built workflows, not autonomous agents
  • Expensive at scale — task-based pricing hits $100+ per 1K operations
  • Not HTTP-native — webhook-only model adds latency
  • No x402, no USDC, no crypto payment layer
  • Can't be called dynamically by an AI agent mid-run
  • Great visual workflow builder for non-developers
  • Huge app catalog for human automation needs
httpay is built for machines, not for no-code humans. Direct HTTP calls, $0.001 per call, zero workflow overhead.

🤖 Get Started in 3 Minutes

From zero to your first paid API call — no signup, no config files, just code.

1
Install x402-fetch (automatic payment handling)
npm install x402-fetch
2
Call any httpay endpoint — it pays automatically
import wrapFetchWithPayments from 'x402-fetch';

// Wrap fetch with your funded Base wallet private key
const fetch = wrapFetchWithPayments(globalThis.fetch, {
  privateKey: process.env.WALLET_PRIVATE_KEY,  // Base network wallet
});

// Call any of 57 services — agent pays automatically via x402
const res = await fetch('https://httpay.xyz/api/gateway/open-meteo/forecast?latitude=40.71&longitude=-74.01');
const weather = await res.json();
console.log(weather.current);  // Live weather data — cost: $0.001 USDC
3
Or use demo mode — completely free, no wallet needed
// Add ?demo=true to any endpoint for a free mock response
const res = await fetch('https://httpay.xyz/api/gateway/open-meteo/forecast?latitude=40.71&longitude=-74.01&demo=true');
// Returns realistic mock data — perfect for development & testing

Frequently Asked Questions

Common questions from developers and agents evaluating httpay

Do I really need zero signup? How does that work?
Yes. httpay uses the x402 protocol: when you call an endpoint, you get a 402 Payment Required response with a payment payload. Your wallet signs and sends a USDC microtransaction on Base, and the gateway immediately processes your request. No registration, no API keys, no session tokens. The wallet is your identity.
What's the difference between httpay and Pylon API?
Both use x402 and USDC. httpay has ~57 services / 10,000+ endpoints vs Pylon's ~20 capabilities. httpay also offers demo mode (?demo=true), a published MCP server (npx @httpay/mcp), and richer agent discovery files (llms.txt, agent.md, openapi.yaml). If catalog breadth matters, httpay wins.
How do I give Claude or GPT access to httpay?
Run npx @httpay/mcp to start the MCP server. Add it to your Claude Desktop or any MCP-compatible client. Your AI assistant can then discover and call all 57 services directly — with automatic USDC micropayments via your configured wallet.
What if I want to compare against a specific API I already use?
Check the Gateway page to see all 57 supported services. If your API is in the list, you can migrate to httpay with a URL change and no more monthly bill. If it's not, let us know and we'll prioritize adding it.
Is httpay reliable enough for production?
httpay proxies directly to upstream providers (OpenWeather, CoinGecko, etc.) — the same data sources you'd use with a direct subscription. For most use cases, reliability is equivalent. For enterprise SLA requirements, a direct subscription may still make sense.
What blockchain / wallet do I need?
httpay uses USDC on Base (Coinbase's L2). You need a wallet with Base USDC. Bridging ETH mainnet or other USDC is straightforward via Coinbase or any Base bridge. The x402-fetch library handles the payment signing automatically.
