Paid ($0.01 USDC via x402). Returns the top 20 active opportunity cards by score as TEASERS — { id, slug, title, category, score, signalCount, lastSeen } only. No evidence and no productAngle (buy GET /v1/opportunity for the full card). While the index is still warming and no active cards exist yet, you get a no-charge 503 corpus_warming (never an empty charged list) — poll the free GET /v1/categories to see when cards go live. Compute-first / settle-after — you are not charged on any error. Response carries fetchedAt.

Paid ($0.02 USDC via x402). Returns up to 50 active opportunity cards in a category, each as a teaser ({ id, slug, title, category, score, signalCount, lastSeen }) plus its summary. Requires ?category=; ?minScore= optionally filters. A missing or unknown category returns a no-charge 400 that lists the valid categories; a valid category with no active cards yet (index still warming) returns a no-charge 503 corpus_warming instead of an empty charged list. Compute-first / settle-after — you are not charged on any error. Response carries fetchedAt.

Paid ($0.05 USDC via x402). Returns one full opportunity card by ?id= or ?slug= (exactly one required, else a no-charge 400): all score components (freqScore, intensityScore, wtpScore), productAngle, summary, evidence[] (verbatim quotes with subreddit, upvotes, permalink), builderMomentum, firstSeen, lastSeen, signalCount, distinctAuthors. Compute-first / settle-after — you are not charged when the id/slug is missing, ambiguous, or not found. Response carries fetchedAt.

Whole-job market brief for agents. One payment returns current trending demand signals, the top 10 highest-scored open opportunities (optionally filtered by category), and per-category counts — equivalent to several separate paid calls. Pass ?category= to restrict the opportunities section to one category slug (an unknown slug returns a no-charge 400 listing the known categories). While the index is still warming and there are no trending signals and no open opportunities, you get a no-charge 503 corpus_warming instead of an empty charged brief. Compute-first / settle-after — you are not charged on any error. Response carries generatedAt plus per-section timestamps.

Paid ($0.03 USDC via x402). POST { "query": "...", "category"?: "..." } to get a demand verdict for any physical-product query. Answers are cached 7 days by normalized query; on a cache miss Demandex matches the query against the mined corpus (signals and cards by keyword) and runs one LLM synthesis call. query must be 3..200 chars. Reads the JSON body first, falling back to ?query=. Verdict shape: { query, verdictScore (0-100), demandTemperature (cold|warm|hot), rationale, topEvidence[] (≤5, each { quote, permalink, upvotes }), relatedOpportunities[] (≤5, each { slug, score }), cache (hit|miss), fetchedAt }. A zero-match query is a real cold verdict (chargeable), not an error. If the LLM is unavailable you get a 503 and are not charged. Compute-first / settle-after.

Paid ($0.10 USDC via x402). Same body as /v1/gauge — POST { "query": "...", "category"?: "..." } (query 3..200 chars; body-first, ?query= fallback). Combines the mined corpus with a LIVE Reddit search run at request time (up to 50 posts, subreddits unrestricted) and one LLM synthesis call. Total compute budget is 45 seconds; on timeout you get a 504 and are not charged. Returns the same verdict shape as /v1/gauge (cache is always miss). A zero-match, empty-search query is a real cold verdict (chargeable), not an error. If the LLM is unavailable you get a 503 and are not charged. Compute-first / settle-after.
