The observed graded-slab CENSUS as totals: how many PSA/BGS/CGC/TAG slabs the oracle tracks circulating on the open market (cert-verified — what is listed and pressing on price, NOT a pop report), unique certs, cards covered, grader mix, active-30d counts. FREE, daily, census leaves committed on-chain. The per-card census with median asks is the paid /api/v1/census ($0.05). Use this when: sizing supply behind a grade, or judging how thin a slab market is before trusting an ask.
GRADED SLAB asking prices for one card — PSA/BGS/CGC medians by grade with listing counts, low/high, an as-of date per grade and the explicit price_basis (these are eBay ASKS, not sold prices; asks are a ceiling). FREE, refreshed daily by the eBay enrichment, merkle-committed on GradedPriceOracle. The LIVE value layer while the USD raw-card panel is frozen — and the basis the graded- slab loan terms are built on. product_id = TCGplayer id from search.

The JAPANESE card market today, as numbers — no card names or prices. How many cards the dealer panel priced this morning (365K+ across 24 games, ~167K carrying BOTH an ask and a buyback bid), the dealer bid as a share of ask at each price band (a bulk floor under ~¥300, a real quote above), depth per game, how much of the board actually moved since yesterday and a week ago, and the day's Merkle root with both chain txs. FREE, refreshes once per ingest day. The only Japanese panel that is LIVE while the USD panel is frozen. Use this when: "what did the Japanese market do today?", "is the dea…

Every graded slab the Loan-Terms Oracle will quote — ~1,100 slabs with grade, live ask median, census depth, liquidity tier (deep/moderate/thin/illiquid), rank and a free_board flag (top 250 by census depth carry a free worked derivation via loan_terms_preview). FREE. v2 (2026-09-12): graded slabs only — raw-card quotes are no longer issued because the USD level froze 2026-09-07. Use this when: an agent needs a product_id + grade to ask for terms, or wants to know which collateral is deep enough to lend against at all.
The sports player directory — ids, names, teams and positions for the leagues currently ON THE BOARD (a league appears once it is in season with enough games for the panel; off-season leagues are absent, not stale), the ids the paid /api/v1/sports/forecast ($0.05) and the fantasy league key on. FREE. Filter by league (mlb, nba, ncaab, ncaaf, nfl, nhl) and/or a name fragment; an absent league returns zero players, which is the honest answer. Use this when: an agent has a player name and needs the id, or wants to enumerate a league's roster on the stat panel.
