Radicle × x402 API

A pay-per-call HTTP wrapper around a Radicle seed node. Each request to /api/* is gated by an x402 micropayment in USDC — no accounts, no API keys.

\n\n \n \n \n \n \n \n \n \n \n \n \n

Endpoint	Description	Price
`GET /api/projects`	List repos on the seed	$0.001
`GET /api/projects/:rid`	Repo metadata	$0.005
`GET /api/projects/:rid/issues`	Repo issues	$0.005
`GET /api/projects/:rid/patches`	Repo patches	$0.005
`GET /api/projects/:rid/commits`	Repo commits	$0.005

\n\n

Without a payment, these routes return 402 Payment Required with a PAYMENT-REQUIRED header. An x402-aware client (or AI agent) signs a USDC payment and retries automatically.

GET /health is free.

Until this is set, the paywall is disabled and `/api/*` returns `503`.\n- `X402_NETWORK` — defaults to `base-sepolia` (testnet). Use `base` for mainnet.\n- `FACILITATOR_URL` — defaults to `https://x402.org/facilitator`. Use the Coinbase CDP facilitator for Base mainnet.\n- `RADICLE_SEED` — the seed node API base. Defaults to `https://seed.radicle.garden/api/v1`.\n\n## Calling it\n\nAny x402-aware client works. With the TypeScript SDK:\n\n```ts\nimport { wrapFetchWithPayment } from \"x402-fetch\";\nimport { createWalletClient, http } from \"viem\";\n// ...build a wallet client, then:\nconst fetchWithPay = wrapFetchWithPayment(fetch, wallet);\nconst res = await fetchWithPay(\"https://.web.val.run/api/projects\");\n```\n\nA plain `fetch` (no payment) just returns `402` with the payment requirements in the `PAYMENT-REQUIRED` header.\n\n## Files\n\n- `main.ts` — Hono app, x402 paywall middleware, route definitions\n- `radicle.ts` — thin client for the Radicle seed node HTTP API\n- `landing.html` — landing page\n",[],[190],["D",1781196151409],["D",1789497655664],{"_11":12,"_123":68},{"_11":12,"_118":119,"_67":68,"_30":66,"_120":121,"_122":24},{"_38":109,"_13":16,"_32":35,"_110":70,"_111":-5,"_112":-5,"_113":-5,"_114":-5,"_115":-5,"_116":14,"_117":12},"ctx",{"_52":-5,"_142":235,"_236":237,"_238":239,"_240":24,"_241":24,"_242":24,"_243":83,"_244":-5,"_245":-7,"_246":-7,"_247":26,"_248":24,"_249":24,"_250":-5,"_251":24,"_252":24,"_253":24,"_254":-5},"ENV",{"_206":207,"_208":209,"_210":16,"_211":212,"_213":214,"_215":216,"_217":218,"_219":220,"_221":222,"_223":224,"_225":226,"_227":228,"_229":230,"_231":232,"_233":234},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
