opendexter
Use OpenDexter to search, price-check, and pay for any x402 API. Trigger whenever the user wants to find paid APIs, call an x402 endpoint, check pricing, see wallet info, or interact with the x402 marketplace.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/branchmanager69/opendexterOpenDexter — x402 API Marketplace
OpenDexter gives you access to the x402 API marketplace across Solana and EVM chains (Base, Polygon, Arbitrum, Optimism, Avalanche). Search, preview pricing, and call any endpoint with automatic USDC payment. No API keys or subscriptions needed for the endpoints — you just pay per call.
Tools
x402_search — Find APIs
Search the OpenDexter marketplace. Results are ranked by a composite score (quality, usage, freshness, reputation, reliability).
Each result includes: name, price (USDC), network, qualityScore (0-100), verified status, seller, and call count.
Highlight verified endpoints (qualityScore 75+). Search is fuzzy — typos still find results.
x402_check — Preview Pricing
Probe an endpoint for payment requirements without paying. Returns per-chain pricing options. Always use before x402_fetch so the user knows the cost upfront.
x402_fetch — Call and Pay
Call any x402 endpoint with automatic payment from the configured wallet. The plugin checks USDC balances across all funded chains and picks the best option. Returns the API response data plus a payment receipt.
If the wallet has no funds on any accepted chain, tell the user to fund their wallet.
x402_pay — Alias for x402_fetch
Same tool, alternate name.
x402_wallet — Wallet Status
Shows which wallets are configured (Solana, EVM), the per-call spending limit, and the active network. Use when the user asks about their wallet or setup.
