How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns an array of sampled price points representing the price curve of the Limitless prediction market, showing how price changes incrementally as USD is stepped out from zero up to the specified maxUsd, with resolution determined by the samples parameter.
Example use cases
Evaluate price impact before trading
“Before I put $1000 into this Limitless prediction market 0xabc123, can you pull the price curve with 50 samples so I can see how much the price will move against me?”
Visualize bonding curve for a market
“I want to chart the full price curve for Limitless market 0xdef456 — get me 100 sample points up to $2000 so I can plot how the AMM price changes as capital flows in.”
Compare market liquidity depth
“Can you get the price curves for Limitless market 0x789abc with default samples and a max of $500, so I can understand how deep the liquidity is and whether it's worth trading there?”
Technical details
Endpoint
POSThttps://chat.sperax.io/api/x402/tools/limitless/getPriceCurve?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to understand the price dynamics or liquidity depth of a specific Limitless prediction market before executing a trade, or when building visualizations of AMM bonding curves. Prefer this over generic DeFi price APIs when working specifically with Limitless markets and needing sampled curve data rather than a single spot price.
Side effects
- Invalid or non-existent marketId returns an error or empty response
- Payment failure via x402 protocol if USDC balance is insufficient
- Malformed request body (missing marketId) results in a validation error
- Network or RPC timeout if the underlying Limitless protocol is unresponsive
- Extremely large sample counts may cause slow responses or timeouts
