Tarnak x402 Toolkit

Endpoints (13 live)

• GET /v1/gpu/prices — Compare GPU rental prices and find the cheapest H100, A100 or RTX rental per hour: a GPU rental comparison across DePIN networks covering decentralized GPU rental, H100 vs A100 cost, GPU cloud pricing and AI compute cost per hour. Use before renting AI compute or choosing the cheapest A100/H100. GET ?model=H100, no API key. $0.01 per call in USDC on Base via x402. (0.01 USDC on Base)
• GET /v1/markdown — URL to markdown: fetch a public URL (or raw HTML) and convert it to clean markdown, title and meta for LLM ingestion, RAG pipelines and agent browsing. GET with ?url= so an agent can call it mid-task without a request body. $0.004 per call in USDC on Base via x402, no API key. (0.004 USDC on Base)
• GET /v1/token/risk — Focused rug-pull and honeypot risk report for a token contract: is it a honeypot, can holders sell, mintable/hidden owner flags, buy and sell tax, top-10 holder concentration, blockers and warnings. No API key, no account. $0.004 per call in USDC on Base via x402 (eip155:8453). (0.004 USDC on Base)
• GET /v1/providers/rank — Compare DePIN compute providers and DePIN compute cost: a GPU provider comparison ranking H100/A100/RTX rental providers by uptime, price and network. Use when choosing a reliable DePIN GPU provider or comparing decentralized GPU rental options; for latency-sensitive placement, compare provider uptime and network before renting. $0.01 per call in USDC on Base via x402, no API key. (0.01 USDC on Base)
• GET /v1/gas — Get the current gas price on Base mainnet: base fee, priority fee and suggested max fee in gwei from a live RPC. Use when an agent needs a Base gas estimate before sending a transaction. $0.002 per call in USDC on Base via x402, no API key. (0.002 USDC on Base)
• GET /v1/util/hash — sha256 hash, slugify, base64 and uuid generation for one string. (0.001 USDC on Base)
• GET /v1/services — Find x402-payable DePIN and data services by task: an x402 service directory to list DePIN services and agent-buyable APIs with price, network and category. Use when an agent needs a service catalog or a cheaper data source. $0.002 per call in USDC on Base via x402, no API key. (0.002 USDC on Base)
• GET /v1/gpu/report — Decision-ready GPU rental cost report for 24-720 GPU-hours. Avoid paying $30 more for a 24h H100 rental. Compare spreads, uptime, and get a rent/hold decision. Returns cheapest and recommended A100/H100/RTX offers, price spread, estimated cost at your hours, 7-day history and a rent/don't-rent call - not just a price list. GET ?model=A100&hours=24, optional compare=H100 and format=markdown; $0.10 per call in USDC on Base via x402, no API key. (0.1 USDC on Base)
• GET /v1/token/verdict — Should your agent buy this token? Keyless token risk verdict: honeypot check, mintable, hidden owner, buy/sell tax, top-10 holder concentration (GoPlus) plus price, liquidity and 24h volume (DexScreener) -> avoid|caution|ok|unknown. Rug-check a memecoin or new token before trading it. Free sample: GET /v1/token/verdict/free (10 calls per IP per day). $0.02 per call in USDC on Base via x402 (eip155:8453). (0.006 USDC on Base)
• POST /v1/text — Text statistics, keyword extraction, sentiment and chunk count for RAG pipelines. (0.003 USDC on Base)
• GET /v1/gpu/report — Decision-ready GPU rental cost report: cheapest A100, H100 or RTX offer, price spread, uptime proxy, estimated cost for your GPU-hours, 7-day price history and a rent/don't-rent recommendation. Use when an agent must choose a GPU provider or budget AI compute, not just list prices. GET ?model=A100&hours=24, optional compare=H100 and format=markdown; $0.10 per call in USDC on Base via x402, no API key. (0.1 USDC on Base)
• POST /v1/repair — Repair and validate malformed JSON from LLM output; return the parsed value. (0.005 USDC on Base)
• POST /v1/extract — Turn a URL or raw HTML into clean markdown, title and meta for LLM ingestion. (0.004 USDC on Base)
