Pay-per-call API gateway for AI agents. 10 services available via x402 — no API keys, no subscriptions.
Frames Registry
Pay-per-call API gateway for AI agents. 10 services available via the x402 payment protocol. No API keys, no subscriptions — just pay per request with crypto.
Base URL
https://registry.frames.ag
Prerequisites
A crypto wallet funded with USDC is required to use paid endpoints. Two options:
AgentWallet (recommended for agents) — server-side wallet that handles 402 detection, payment signing, and retries automatically via a single POST /x402/fetch call. No private key management needed on your side.
Self-managed wallet — any EVM wallet (Base) or Solana wallet with USDC. You sign x402 payment headers directly.
Quick Start
Set up a wallet — create an AgentWallet or fund your own wallet with USDC
Discover services: GET https://registry.frames.ag/api/services
Read service docs: GET https://registry.frames.ag/api/service/{slug}/skill.md
Check pricing: GET https://registry.frames.ag/api/pricing
Make a paid request — via AgentWallet's /x402/fetch or directly with x402 headers (see Payment Protocol below)

Payment Protocol (x402)
All paid endpoints use the x402 payment protocol. No API keys needed.
Flow:
Call any paid endpoint without a payment header
Receive 402 Payment Required with a PAYMENT-REQUIRED header (Base64 JSON with price, network, payTo address)
Sign a payment for the requested amount on your chosen network
Retry the same request with the PAYMENT-SIGNATURE header
Receive the response plus a PAYMENT-RESPONSE confirmation header
Failed requests are automatically refunded.

Agent Integration
With AgentWallet (recommended)
AgentWallet is a server-side wallet for AI agents. It manages keys, balances, and x402 payment signing so agents don't need to handle crypto directly.
Authenticate with AgentWallet (email OTP → API token)
Fund your wallet with USDC on Base or Solana
Call any Frames Registry endpoint through AgentWallet's proxy:
POST https://frames.ag/x402/fetch
{
"url": "https://registry.frames.ag/api/service/twitter/api/search-tweets",
"method": "POST",
"body": { "query": "AI agents" }
}
AgentWallet detects the 402 response, signs payment, and retries automatically.
Direct x402 (self-managed wallet)
Requires an EVM or Solana wallet with USDC and the ability to sign EIP-3009 or SPL transfers.
Make the request to the paid endpoint
Parse the PAYMENT-REQUIRED header from the 402 response (Base64 JSON with price, network, payTo)
Sign a payment authorization for the exact amount
Retry with the PAYMENT-SIGNATURE headerdon't have the plugin yet? install it then click "run inline in claude" again.
