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.
| Decixa | x402.direct | |
|---|---|---|
| Listings tracked | 30,000+ | ~4,000 |
| x402 verification | HTTP 402 probe (real) | Metadata scoring |
| Capability classification | 9 verb-based axes | — |

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.
| Parameter | Type | Description |
|---|---|---|
intent (required) |
string | What you want to do (e.g. "summarize news articles") |
budget |
number | Max USDC per call (e.g. 0.01) |
latency |
string | low / medium / high |
min_similarity |
number | Similarity threshold (0.2–0.9, default 0.5). Out-of-range → 400 |
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.
| Parameter | Type | Description |
|---|---|---|
intent (required) |
string | Natural-language intent (mapped to server's task query param) |
tag |
string | Filter by capability tag (e.g. "Market Data", "Risk Score") |
budget |
number | Max USDC per call |
latency_tier |
string | low / medium / high |
execution_mode |
string | sync / async |
pricing_model |
string | per_call / subscription / hybrid |
min_similarity |
number | Similarity threshold (0.2–0.9, default 0.3). Out-of-range → 400 |
sort |
string | relevance (default) / price_asc / price_desc / latency_asc / trust / calls (deprecated) |
limit |
integer | Results per page (1–50, default 20) |
offset |
integer | Pagination offset |
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
resolveinstead. Shares schema and handler withresolve.
browse_apis (deprecated alias for discover)
DEPRECATED in v0.1.7. Will be removed in v1.0.0. Use
discoverinstead. Shares schema and handler withdiscover.
get_api_detail
Get full details for a specific API by ID.
| Parameter | Type | Description |
|---|---|---|
api_id |
string | API ID from resolve or discover |
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
| Old | New | Notes |
|---|---|---|
search_apis({intent, capability, agent_ready}) |
resolve({intent, min_similarity?}) |
Drop capability / agent_ready. They are silently ignored server-side (D-059). |
browse_apis({task, capability, agent_ready, sort}) |
discover({intent, sort}) |
task → intent, drop capability / agent_ready. Default sort changed trust → relevance. |
list_capabilities({}) |
(removed) | Capability filtering is no longer needed. Pass intent text + optional tag filter. |
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.
