Server Details

Check paid API offers before your agent spends. Qualifying routes: $0.003 USDC. Normal misses: free.

The last two health checks of this connector failed. If this server requires authentication, missing or expired test credentials may be the cause. A test profile lets Glama authenticate for health checks and discover tools; it is separate from your personal connections.

A4.7/5.0

Scored across 3 tools

Disambiguation4/5

The three tools have distinct roles: preview discovers candidates for free, validate checks a listed URL for free, check performs a paid live probe with signed evidence. However, check and validate both assess endpoint readiness, and the verbose descriptions explicitly differentiate them, leaving minor potential for confusion.

Naming Consistency4/5

All tool names are single lowercase action verbs (check, preview, validate), which is a consistent pattern, though it deviates from the more common verb_noun convention. No mixing of styles is present.

Tool Count5/5

Three tools is well-scoped for a focused discovery/pre-flight checking service; each tool covers a distinct phase (discover, validate, paid check) and earns its place.

Completeness4/5

The surface covers discovery, free validation, and paid pre-flight check with signed receipt. Minor gap: no separate tool for reconciling settlement_state=unknown or verifying a receipt later, but core workflow is complete.

One inventory of 33,000+ paid endpoints from Coinbase Bazaar and mpp.dev, rebuilt daily. No signup, no keys.
