How this service works
Compute mid price and bid-ask spread in basis points — call when computing mid and bid-ask spread in basis points. Use on caller-supplied ticks/returns when agents need signal prep without a licensed live market feed (ottoai-class demand, first-party transform). Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or med…
Output
A deterministic JSON object containing the computed mid price (average of bid and ask) and the bid-ask spread expressed in basis points, calculated from the provided bid and ask prices.
Example use cases
Spread monitoring for algo trading signals
“I have a bid of 1.0820 and an ask of 1.0835 — what is the mid price and how wide is the spread in basis points?”
Pre-trade signal prep from tick data
“I'm preparing tick data for a model. Bid is 49850.00 and ask is 49862.50 — can you compute the mid price and spread in bps?”
Portfolio liquidity cost estimation
“For my portfolio rebalancing analysis, I need the bid-ask spread in basis points — the bid is 203.10 and the ask is 203.45.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/spread-bpsWhen to prefer
Choose this endpoint when you need a lightweight, stateless, deterministic computation of mid price and bid-ask spread in basis points from your own tick or quote data, without requiring a licensed live market feed. Ideal for signal preprocessing pipelines, backtesting, or any scenario where you supply the bid/ask values yourself and want a cheap, fast, reproducible result.
Side effects
- Missing bid or ask field returns a validation error
- Non-numeric bid or ask values cause a parse or type error
- Ask price lower than bid price may produce a negative or nonsensical spread
- Payment failure via x402 prevents execution and returns a 402 response
