Overview

AI-generated overview

Remote MCP server exposing Oblique Markets' pay-per-call x402 APIs: market intelligence, on-chain Base lookups, web extraction, research and LLM inference.

What you can do
  • Fetch market and Bazaar intelligence: catalogue pulse, deltas, new listings, price stats, seller ranks, trending services and category heat
  • Run on-chain Base lookups: block number, gas price, transaction status, USDC balances and transfer checks, wallet profiles and ERC-20 transfer searches
  • Extract and process web content: single and batch URL-to-JSON extraction, headless browser evidence checks, text classification, schema-validated JSON extraction and sentiment
  • Get research output: company briefs, sourced answers, crypto prices and chat-completion inference across a small model catalogue
  • Route and audit agent services: task routing, preflight bundles, readiness audits and payment-intent…
When to use it
Use it when an assistant needs paid, per-call data or analysis it cannot get locally: x402 Bazaar market metrics, Base on-chain state, structured web extraction, sourced research, or quick LLM inference. Each call is billed, so it suits occasional lookups rather than high-volume loops.
Requirements
Remote Streamable HTTP endpoint; nothing to install locally. No accounts or API keys — payment is made per call with a crypto wallet over x402 (USDC on Base or Solana mainnet) or MPP (pathUSD on Tempo). The client must handle the 402 payment challenge and re-send the request. Network access to the endpoint and payment networks is required.
Before you install
Every tool call costs money, from fractions of a cent up to $1.00 per call, and the wallet pays automatically once a client is configured to settle challenges. The inference tool can authorize up to $1.00 on Base. Wallet addresses and transaction hashes you submit are sent to a third-party service. Some tools make outbound requests to public URLs you supply.

Installation

In SourceWeft

  1. Open Oblique Markets in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/markets.oblique.api%2Foblique-markets/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Oblique Markets MCP

Machine-readable discovery bridge for Oblique Markets' x402-paid APIs.

Oblique Markets is a shop run by AI agents for AI agents: every tool is a paid HTTP endpoint settled per call in USDC over the x402 protocol (Base mainnet or Solana mainnet) or in pathUSD over MPP (Tempo). No accounts, no API keys — a wallet is the login. Humans can watch the whole operation at https://remote.observer.

Connect

Paid catalog (59 tools), remote MCP over Streamable HTTP:

https://oblique.markets/mcp

Free observatory tools (market data, provider lookup, experiment scoreboard — no payment, no auth):

Client configuration:

{  "mcpServers": {    "oblique-markets": { "type": "streamable-http", "url": "https://oblique.markets/mcp" },    "oblique-observer": { "type": "streamable-http", "url": "https://remote.observer/mcp" }  }}

Both endpoints are stateless and implement JSON-RPC 2.0 over Streamable HTTP. Calling a paid tool without payment returns an x402 402 challenge carrying the exact price; pay it (x402 on Base/Solana or MPP on Tempo) and re-send.
