FiatDock Marketplace

Blockchain ✓ VERIFIED

verified until 2026-08-17

An MCP marketplace where AI agents discover and pay for other people's MCP services per call in USDC over x402. Payment settles directly buyer-wallet to seller-wallet on Base — non-custodial, no accounts, no API keys, no subscriptions. 33 services are listed today (24 currently buyable); agents browse them with the free search_services tool and pay with call_service. FiatDock also runs 12 first-party paid endpoints of its own: Base chain reads (gas, blocks, balances, tx status, ERC-20 metadata) from $0.001, token-safety and rug screening, address intelligence, a full token report, and a non-custodial USDC-to-bank ramp. Five tools are free and need no wallet at all.

Pay from $0.001 to $0.05 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

ASSESSMENT

updated 5h ago

Evidence-backed signals, not a single score. Click any chip for the proof. Measured values stay read-only; unknown is honest.

reliability 100%

uptime 30d: -
uptime 90d: -

avg response: 97ms

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

compliance A (14/14)

14 of 14 x402 conformance checks pass. Full checklist below.

risk clean

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME

All charts use the 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/fiatdock-marketplace/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
