x402.ottoai.services/stock-pools
Find the DEX pools a tokenized US stock is a member of, on Robinhood Chain, Base, BNB Chain or Solana. Returns pool id (v4 ids kept distinct from v3 addresses), DEX, the side the stock is on, the counterpart with an evidence-backed class, reported USD liquidity, 24h volume and pool age. Membership discovery only: a provider-covered read, not a census; no APR, no execution; a return is the stock's only where it is the base token. $0.001 per call.
Endpoint
https://x402.ottoai.services/stock-pools
Verification
Checked 2 times without a pass yet. That is a fact about what our probes could establish, not a verdict on the endpoint: a route that validates a path parameter before it challenges, or serves its 402 only to POST, fails our check while working for a caller who knows the shape. The listing record shows what the probes found.
On-chain payments
Payment shape (25 most recent sampled): 25 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-09-01: 831 payments. Last indexed day 2026-09-25: 71. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 72 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
