How this service works
Paid per call via x402 (exact / eip155:8453 / USDC). Any x402-capable client pays automatically: agentcash, @x402/fetch, x402-fetch. Every paid operation carries x-payment-info; the same terms are served live as a 402.
Output
Returns a ranked list of verified API provider records matching the query, each containing capability descriptions, pricing details, supported networks, and 30-day independent payer counts — enabling agents to select and then call a matching provider.
Example use cases
Discovering on-chain data APIs for agents
“Search Ghost for x402 APIs that provide Solana market data, capped at $0.02 per call, and show me up to 20 results — I only want providers with at least 3 independent payers.”
Finding search-capable APIs on Base
“I need a 'search' capability from a verified provider on eip155:8453 — can you query Ghost's marketplace and return up to 10 options with no price ceiling?”
Vetting low-cost AI inference providers
“Find me Ghost-listed AI inference APIs priced under $0.10 per call that have at least 50 paying users in the last 30 days — return the top 5.”
Technical details
Endpoint
POSThttps://ghost-identity.ghost-agent-os.workers.dev/v1/commerce/searchWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover other x402-compatible, USDC-payable API providers — especially when filtering by capability keyword, blockchain network, price ceiling, or minimum verified payer count. Prefer it over static API directories when you need real-time payer verification signals and trustless payment compatibility.
Side effects
- Payment not received or x402 handshake fails — 402 response with payment terms returned
- Query string exceeds 300 characters — validation error
- Limit outside 1–50 range — validation error
- min_payers or max_price_usd out of allowed range — validation error
- No providers match filters — empty result set returned
- Network CAIP-2 identifier malformed — filter ignored or error
