Gate402
https://gate402.app/v1/proxyPay-per-call tools for AI agents, paid in USDC over HTTP 402 (x402) with no signup: Base on-chain and DEX data, token risk checks, news, SEC filings, web pages as Markdown, and $1 file tools. LLM calls on open models are relayed to openrouter.ai (a hosted model API) and priced per token. Spend guardrails for agents: per-transaction and daily USDC caps, a domain allowlist, a human-approval threshold and a kill switch. GPU owners can list an OpenAI-compatible endpoint and be paid per call. No GPUs are online yet. Also an MCP server: npx -y gate402-mcp.

https://gate402.app/v1/proxy
Fetch any public URL, render client-side JS, strip nav/ads, return clean LLM-ready Markdown.
https://gate402.app/v1/proxy/stealth
Anti-bot fetch for Cloudflare / JS-heavy protected pages: routed through rotating residential proxies with automatic JS rendering and CAPTCHA solving, returned as clean LLM-ready Markdown. Best-effort on the hardest targets.
https://gate402.app/v1/minify
Compress text before an LLM reads it: strip filler, collapse JSON, densify prose. The response reports estimated input and output tokens (from character and word counts, not a model tokenizer) and the percent saved on your own text.
https://gate402.app/v1/onchain
On-chain wallet & token intelligence on Base: native + ERC-20 balances, EOA/contract detection, tx count, and token metadata. From public RPC.
https://gate402.app/v1/dex
Live DEX price, liquidity, and 24h volume for a Base token across its trading pairs.
https://gate402.app/v1/token-risk
Rug/tradeability risk verdict for a Base token: a 0-100 score and SAFE/CAUTION/AVOID call from liquidity depth, 24h volume, DEX diversity, pool age, ERC-20 validity, holder concentration, and a live honeypot/sell-tax simulation. Judgment for trading agents, not raw data.
https://gate402.app/v1/launches
Radar of the freshest Base token launches (newest DEX pools), lightly pre-screened by liquidity/age/flow with quickFlags for obvious junk. Top-of-funnel discovery for trading agents; feeds token-risk / momentum / best-swap. From GeckoTerminal.
https://gate402.app/v1/best-swap
Best-execution intel for a Base token: which DEX pool to trade on and the estimated price impact + total cost for a given trade size, ranked across pools with a split suggestion. Constant-product estimate for trading agents: the execution plan, not a firm quote.
https://gate402.app/v1/momentum
Factual momentum + order-flow signal for a Base token: price trend (5m-24h), buy/sell pressure, volume trend, classified RISING/FALLING/FLAT + ACCUMULATION/DISTRIBUTION and gated by a live honeypot check. The read for trading agents, not a prediction.
https://gate402.app/v1/news
Recent news headlines + heuristic bull/bear sentiment for a ticker or topic.
https://gate402.app/v1/edgar
Latest SEC EDGAR filings (10-K/10-Q/8-K) for a US ticker or CIK, with document links.
https://gate402.app/v1/infer
Chat completions on open models, relayed to openrouter.ai (a hosted model API); gate402 runs no GPUs for this. The 402 quote prices your prompt plus max_tokens, and you pay that quote: unused tokens are not refunded. Per 1M tokens, input / output: llama-3.1-8b $0.08 / $0.128, llama-3.1-70b $0.64 / $
https://gate402.app/v1/dedup
Cache for repeated queries: an exact match first, then the closest stored text at 0.88 cosine similarity or higher. It hashes words and character trigrams rather than running a model, so the same question in other words is a miss. The response reports the similarity and the lookup time.
https://gate402.app/v1/demand
