Ask the XH Agents AI Trading Assistant a market question

Enriches a company, domain or person from public structured sources (Wikidata, the public LinkedIn company page, Clearbit autocomplete): industry, size, headquarters, founding year, official website, stock listing and social handles.

Thirteen production playbooks from running an x402 paid API on Base: shipping the endpoint, the payment-verifier rules, the real-money buyer test, the Base RPC capability audit, CDP authentication, directory registration, consolidating Cloudflare/Solana data, an rclone Google Drive bridge, AdSense, multi-size ad slots, nginx route recovery and secure Telegram alerts. Each item carries the mechanism, the commands, the pitfalls that cost us real money and how to verify the result.

A dated, freshly rebuilt brief on where demand is in the agent-payment economy: what builders and agents are discussing and paying for in the last 30 days (Hacker News, GitHub, Polymarket, marketplace listings), plus our own paid-endpoint call and settlement performance. Rebuilt every day at 06:00 WIB; yesterday's copy is not the product.

Funding rate, open interest and price trend for a perpetual pair (Binance public data) plus protocol TVL change from DefiLlama, combined into a labelled sentiment with its weights shown.

Domain & email audit — SPF, DMARC, DKIM, MX, TLS certificate, HSTS and security headers, scored 0-100

Current Base base fee, suggested priority fees and USD cost estimates for a transfer or an ERC-20 transfer.

Build an x402 paid endpoint that passes the validator, gets indexed and takes real USDC. End-to-end recipe for turning any HTTP capability into an x402 endpoint that an unknown agent can find, pay for and consume: the payment gate, the verifier rules, per-route pricing, the concurrency traps, the nginx wiring, the discovery surface, plus the money-path bugs we only found when real USDC moved. Comes with the exact commands we run.

Connect a headless VPS to a user's Google Drive (rclone, no browser on the server). Give a server permanent, scriptable access to someone else's Google Drive: one interactive authorisation on a machine with a browser, then bidirectional sync from the server forever. This is the exact flow we use for both a personal Drive bridge and a scheduled VPS backup.

Register an x402 endpoint so agents can find and pay it (x402scan + Coinbase Bazaar). The complete discovery path for an x402 endpoint: publish machine-readable discovery documents, pass the official validator, list on x402scan, understand what actually triggers Coinbase Bazaar indexing, and prove the listing exists from the registry's own API instead of a success toast. Written from an endpoint set that went from 0 to 11 listed resources, with the exact API payloads a registry expects today.

YouTube Shorts automation with AI: queue → render → upload → notify. A 3x/day pipeline that takes product photos from Google Drive, renders a 720x1280 Shorts video with Ken Burns motion, uploads it to YouTube via the Data API v3, updates a static showcase page and reports to Telegram. Every step below ran in production; the numbers are the ones we actually use.

Ask the XH Agents knowledge base (15 field notes on infrastructure, x402 and agent tooling)

Verifies that a transaction hash settled a USDC payment to a given recipient, returning the parsed transfer and confirmation count.

Pulls one X/Twitter post by URL or id (text, author, metrics, language) and/or a public LinkedIn company page (industry, size, headquarters, specialties, followers) as structured JSON.

ERC-20 metadata, proxy detection and free DEX liquidity data for a token on Base, with the checks that could not be performed stated explicitly.

One 0-100 safety score for a Base token, decided before the agent buys: liquidity on the deepest pair, top-10 holder concentration, owner powers found in the bytecode (mint/blacklist/pause/fee setters), upgradeability from the EIP-1967 slot, explorer/Sourcify verification, the creator's history, and the price impact of a small trade. Returns safe/caution/danger with every component printed ...

x402 seller trust leaderboard — every catalogue origin probed outside-in and scored 0-100, with the verdict spread and the most common reasons points were lost

Balances, contract status, nonce, recent USDC activity and known-address labels for any Base address.

Runs a live web search and returns ranked results with title, URL, domain and snippet, then fetches the top pages and returns their extracted readable text — content retrieval, not just links.

Scans the last blocks for USDC and WETH transfers above a USD threshold and returns the largest movements with direction and counterparties. Pending-mempool visibility needs a node with txpool access, which this reports instead of faking.

Fetches any x402 endpoint, decodes its 402 challenge and reports conformance: version, accepts fields, PAYMENT-REQUIRED header, bazaar metadata and price.

Searches Coinbase Bazaar and the x402-list directory at once and returns de-duplicated endpoints with price, network, payTo and description, so an agent can find a service to pay without knowing it in advance.

Check an x402 endpoint before paying it. Give it any x402 URL: it makes the unpaid request, decodes the 402 challenge, reads the origin's .well-known/x402 and openapi.json, inspects the payTo address on-chain (USDC inflows, distinct senders, EOA vs contract vs smart-wallet delegation), and returns a 0-100 trust score with buy/watch/avoid plus the evidence and the penalties behind every point ...
