SuperUzerAI sells IT and DevOps eBooks, an Automate Passive Income kit, and Instagram automation apps.
Pay each call in USDC on Solana or Base. An unpaid request returns HTTP 402 before the body is accepted, including an empty or invalid body. The PAYMENT-REQUIRED header lists both networks. Amounts are USDC atomic units (6 decimals, so $0.01 is 10000).
GET /api/health is free. It returns {"status":"ok","uptimeSeconds":number} for a liveness check. Do not send a payment.
Solana solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp pays DDBuNmddRxuJ5Kh9wfqhyzXZ7VvsuC5wuNvAMUi2hvMk. Base eip155:8453 pays 0x843c449C79fCB0eF37C4cef3dD6762018835c20E.
AgentCash discovery pays Solana mainnet (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp) and Base (eip155:8453). Tempo (eip155:4217) is listed as a testnet and is only used when MPP is enabled. Solana devnet and Base Sepolia are for local 402 tests, not AgentCash wallets.
GET /api/guides/search?q= costs $0.005 (5000 atomic units). It returns short snippets and a buy URL. Full chapter markdown is not sold here; the eBook files are not part of this API.
POST /api/automate-wealth/playbook costs $0.25 (250000 atomic units). JSON body: { "niche"?: string, "audience"?: string }. Returns a 6-hour launch playbook.
POST /api/instagram/reel-script costs $0.10 (100000 atomic units). JSON body: { "topic": string, "angle"?: string }. Returns hook, script lines, caption, and hashtags. It does not render or upload video.
A human-readable catalog with prices, curl examples, and the x402 flow is at /agents.
Schemas, decimal USD prices, and per-network atomic accepts are in /openapi.json.
Headless bots pay with @x402/fetch wrapFetchWithPayment. The example is scripts/bot-pay-example.mjs (Solana and Base). Set SOLANA_RPC_URL for the Solana transaction builder. The default is https://solana-rpc.publicnode.com. Do not use https://api.mainnet-beta.solana.com; it returns HTTP 403 to many clients. The 402 omits recentBlockhash because a cached hash expires; fetch a new one immediately before signing. Do not pay from the Solana payout wallet.
This API does not call a Solana RPC. Verify and settle are HTTP requests to the PayAI facilitator. Solana extra.feePayer on the 402 comes from that facilitator's /supported response.
POST /api/video/caption downloads a public video, transcribes it with local faster-whisper tiny int8 (1 CPU thread), and burns word-level captions. JSON body: { "url": string, "language"?: string, "style"?: "karaoke" | "bold" | "minimal" }. Price is $0.08 per started minute. The maximum input is 60 seconds and 50000000 bytes, so the maximum charge is $0.08.
POST /api/video/ffmpeg runs one local ffmpeg operation. thumbnail costs $0.02. trim, reframe (9:16), and audio (mode replace or add) cost $0.03. concat of 2 to 5 videos costs $0.05. Each source must be at most 60 seconds and 50000000 bytes.
After payment the caption and ffmpeg routes return HTTP 202 with jobId, statusUrl, queuePosition, and estimatedWaitSeconds. Jobs run one at a time in a FIFO queue of 20. Poll GET /api/video/jobs/{id} (free, no payment header) until status is done. outputs.mp4Url, outputs.srtUrl, or outputs.imageUrl appears on that poll when the job is done. Do not pay again for the status URL or the signed file URL. Links expire.
When the queue is full the route returns HTTP 503 and Retry-After before any payment is settled, including an unpaid request. A request that is not rejected returns HTTP 402 until it is paid. These tools do not call Google, Gemini, Veo, OpenAI, or a paid speech API.
Base settlement uses https://facilitator.payai.network and does not need a Coinbase API key. Coinbase Bazaar catalog discovery is not available in this mode.
