What you can do

resolve({ intent: "get real-time BTC price" })
→ Returns top recommendation + up to 2 alternatives, ranked by Phase 3 vector + scoring

resolve({ intent: "summarize Reddit posts", budget: 0.005 })
→ Filters by cost, returns trust_evidence and latency tier

discover({ intent: "transcribe audio", budget: 0.01, sort: "price_asc" })
→ Returns multiple x402-verified candidates so the agent can choose

Why Decixa

Unlike x402.direct, Decixa verifies x402 compliance by actually probing each endpoint — not just metadata analysis.

Tools

resolve (recommended, replaces search_apis)

Find the best API for a task using natural language. Returns top recommendation + up to 2 alternatives. Decixa uses Phase 3 vector + scoring (vector 0.70 + latency 0.05 + price 0.05 + tiebreak 0.20). When no candidate clears the similarity threshold, returns recommendation_status='no_match' with up to 2 suggestions.

Response includes recommendation_status ("resolved" or "no_match").

discover (recommended, replaces browse_apis)

List APIs ranked by intent. Returns multiple candidates so the agent can choose. Verified-x402 only.

Response includes search_mode, min_similarity_applied, no_match_reason, top_candidates_below_threshold.

search_apis (deprecated alias for resolve)

DEPRECATED in v0.1.7. Will be removed in v1.0.0. Use resolve instead. Shares schema and handler with resolve.

browse_apis (deprecated alias for discover)

DEPRECATED in v0.1.7. Will be removed in v1.0.0. Use discover instead. Shares schema and handler with discover.

get_api_detail

Get full details for a specific API by ID.

Returns: endpoint URL, pricing, capability, tags, agent_compatibility, schema info, use_cases, trust_evidence (score / uptime_7d / p95_latency_ms / payment_req_parsed / last_checked / last_probed_at), provider, and verified_live flag. Prefer trust_evidence.score over legacy trust_score for new clients.

get_index

Entry point for agents new to Decixa. Returns platform overview, endpoints, and usage guidance.

No parameters required.

Migration from v0.1.6

Strict MCP clients note: if your MCP client validates additionalProperties: false, it will reject capability / agent_ready arguments at the client side. Tolerant clients let them through, but Decixa silently ignores them server-side. Either way, remove them.
