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) Services (10) Service Slug Description Endpoints Price Range Twitter API twitter Full Twitter API access - users, tweets, search, communities, spaces, trends, and more via twitterapi.io 26 $0.005 - $0.02 AI Generation API ai-gen Run AI models for image, video, audio, and 3D generation 1 $0.01 x402 Test Service test Test x402 payment flows on Base Sepolia (EVM) and Solana Devnet.

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.

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 header
