  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• health

  Free. Liveness and the settled-call counters per route.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• receipt

  Free. Look up a signed delivery receipt by id (returned with every paid call) and its verification key.

  Parameters:

  • id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• same_stock

  Use this when you need the same stock from every issuer on Base in one call: send a ticker (NVDA, AAPL, TSLA) and get, per issuer — ST0x (wtNVDA) and Coinbase tokenized stocks (NVDAc, B20) — the genuine contract verified against the issuer's own registry, live price, premium/discount vs the real share in bps, pool depth and 24h volume, the ST0x-vs-Coinbase spread, any direct cross-issuer pool, and every impostor token using the same symbol. xStocks flagged as not on Base. Costs $0.05 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/tokenized-equities/same-stock/{ticker}

  Parameters:

  • ticker (required) — string — stock ticker (NVDA), ST0x symbol (wtNVDA) or Coinbase symbol (NVDAc)

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• st0x_premium

  Use this when the question is whether an ST0x tokenized stock on Base trades above or below the real share: send a ticker (NVDA, wtAAPL, FGI) and get the premium/discount in basis points from the deepest USDC pool (live) and the last Raindex fill vs the exchange quote, corrected for the ERC-4626 wrapper rate, with market session, age of every leg, pool depth, any cross-issuer pool (wtNVDA vs Coinbase NVDAc), and a one-sentence read. Unknown ticker -> 404, no charge. Costs $0.02 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/tokenized-equities/st0x/premium/{ticker}

  Parameters:

  • ticker (required) — string — stock ticker (NVDA), ST0x symbol (wtNVDA) or Coinbase symbol (NVDAc)

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• st0x_pulse

  Use this when you want to know what is actually trading in tokenized stocks on Base right now: the last 24 hours on ST0x's own DEX (Raindex) per token — USDC volume, trade count, last on-chain price and time — plus each token's issued vault supply and ERC-4626 wrapper rate, sorted by volume, with platform totals. Read straight from the public subgraphs and RPC; refreshed every 5 minutes. Costs $0.01 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/tokenized-equities/st0x/pulse

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• st0x_registry

  Use this when you need to resolve a stock ticker to its ST0x on-chain token, or check whether a contract is a genuine ST0x tokenized share: the complete issuer registry for all 54-56 names on each of four chains (Base, Ethereum, HyperEVM, Robinhood Chain) — wrapped (wtNVDA, ERC-4626) and unwrapped (tNVDA, ERC-20) addresses, the ERC-1155 receipt vault, ISIN, TradingView symbol, listed flag. Versioned from the issuer's own registry; refreshed hourly. Costs $0.001 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/tokenized-equities/st0x/registry

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• solana_token_verdict

  Use this when an agent or a human asks 'is this Solana token safe, a joke, or a rug?': send one mint address, get a graded verdict (BASED / MID / COOKED / RADIOACTIVE), a one-liner, a short roast, and the facts behind the grade: price, liquidity, 24h volume, FDV, pair age, holder count, top-10 concentration, mint and freeze authority, LP lock, rugcheck risk flags, launchpad. Grade is rule-based and reproducible from the facts. Entertainment, not trading advice. Costs $0.02 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/solana/token-verdict/{mint}

  Parameters:

  • mint (required) — string — Solana token mint address (base58)

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• ai_progress_latest

  Use this when you need the current state of AI progress in one call: the latest reading of 129 public series (frontier benchmark scores GPQA/HLE/ARC-AGI/METR, Epoch compute trends, AGI odds on Polymarket/Manifold/Kalshi, model pricing, AI stocks and crypto, energy, space, robotics, biomed, research output). One JSON row per series: latest and previous value with dates, % change, signal quality, source URL. Free 3-row sample at /preview. Costs $0.005 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/ai-progress/latest

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• ai_progress_as_of

  Use this when you need AI progress as it stood on a past date: the reading of the same 129 series (benchmarks, compute, AGI prediction-market odds, model pricing, AI stocks, energy, space, robotics, research output) taken on YYYY-MM-DD. Dated ids are listed free at /. Same per-series shape as /ai-progress/latest, so you can diff dates yourself; /ai-progress/what-changed does the diff for you. Unknown id -> 404. Costs $0.005 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/ai-progress/as-of/{id}

  Parameters:

  • id (required) — string — reading date YYYY-MM-DD, from the free menu

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• ai_progress_what_changed

  Use this when the question is what moved in AI progress between two dates: the acceleration between two readings of 129 series (benchmarks, compute, AGI odds, model pricing, AI stocks and crypto, energy, space, robotics, research output). Per series: from/to value and date, absolute and % change, and whether a new observation landed. Dates are YYYY-MM-DD ids from the free menu at /. Costs $0.01 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/ai-progress/what-changed/{from}/{to}

  Parameters:

  • from (required) — string — earlier reading id
  • to (required) — string — later reading id
