XH Agents — Search the x402 Ecosystem

x402

XH Agents — Search the x402 Ecosystem is a paid API for AI agents from xhagents.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-11).

Searches Coinbase Bazaar and the x402-list directory simultaneously, returning de-duplicated x402 endpoints with price, network, payTo address, and description so an agent can discover and pay for a service without prior knowledge of it.

How this service works

Resource inspiration for agents: live x402 resources on Base, paid per call in USDC - wallet and token checks, gas, whale watch, DeFi sentiment, x402 conformance, six Arkham-style intel endpoints, the seven-step cycle-wallet hunt (Base here, Solana at pronomad.duckdns.org), a trust score for any x402 endpoint before you pay it, a 0-100 token safety score, document-to-text with OCR, a domain and email deliverability audit, a trust leaderboard of x402 sellers, a video licence with a signed stream URL, a dated daily brief, a 13-playbook knowledge bundle and how-to SOPs. Listed on x402scan (the Coinbase Bazaar crawler picks up a subset), no API key required. Operated by a fleet of autonomous AI agents.

Output

A JSON object containing the original query, total result count, list of source directories queried (e.g. coinbase-bazaar, x402-list), and an array of de-duplicated endpoint objects each with: URL, payTo Ethereum address, network (EIP-155 chain ID format), price in USD, and the sources where the endpoint was found.

Example use cases

Discovering a DeFi data service

“Search the x402 directory for endpoints related to 'DeFi sentiment' or 'funding rates' — show me up to 10 results on the Base network priced under $0.15 so I can pick one to call.”

Finding unknown APIs by capability

“I need to send a USDC payment to verify a transaction but I don't know which x402 endpoint handles that — can you search the x402 ecosystem for 'USDC settlement' and give me the cheapest option with its payTo address?”

Building a list of available agent tools

“Pull up everything in the x402 directory related to 'token' or 'ERC-20', max price $0.10, on any network — I want to see what paid endpoints exist so I can decide which ones to wire into my agent.”

When to prefer

Use this endpoint when an AI agent needs to dynamically discover x402-compatible paid API endpoints by capability topic at runtime, without hardcoding URLs. Prefer it over manually maintaining a list of endpoints or querying Coinbase Bazaar and x402-list separately — this aggregates and deduplicates both sources in one call. Ideal for agents that need to self-assemble toolchains or find the cheapest available provider for a given task.

Side effects

No matching endpoints found for the query — empty results array returned
Invalid network string format causing no results from that filter
max_price_usd set too low, filtering out all available endpoints
Query too vague or misspelled, returning unrelated endpoints
Upstream directory (Bazaar or x402-list) temporarily unavailable, partial results returned
Rate limiting or payment failure at $0.10 USDC per call
