x402
Mycelia Signal ETH Same-Day Price Distribution Oracle is a paid API for AI agents from api.myceliasignal.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).
Returns ETH same-day price distribution statistics (median, p10–p90 quantiles, entropy) derived from Polymarket prediction markets, delivered as an Ed25519-signed attestation

How this service works
ETH same-day price distribution from Polymarket — median, quantiles (p10-p90), entropy — Ed25519 signed attestation
Output
Returns a structured payload containing: the median ETH price implied by Polymarket same-day prediction markets, quantile estimates from p10 through p90 (showing the probability-weighted price range), a Shannon entropy value indicating market uncertainty, and the full dataset signed with an Ed25519 private key for cryptographic attestation and tamper-proofing.
Example use cases
ETH options strategy calibration
“I'm setting ETH options strikes for today's expiry — can you get me the Polymarket-derived price distribution for ETH including the median, p10, and p90 quantiles so I can calibrate my range?”
Crypto trading bot uncertainty gate
“Before my bot places any ETH trade today, I want it to check the prediction market entropy on ETH price — if uncertainty is too high, it should hold. Can you fetch the signed ETH price distribution from Polymarket?”
Verified ETH market signal for audit trail
“I need a cryptographically verifiable snapshot of where Polymarket thinks ETH will close today — median, quantiles, and entropy — with an Ed25519 signature so I can store it as a tamper-proof record.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/prediction/eth/priceWhen to prefer
Choose this endpoint when you need a probabilistic, crowd-sourced view of ETH's same-day price rather than a single spot price — especially when you need cryptographic attestation for auditability, want quantile-based uncertainty bounds (p10–p90) rather than a point estimate, or are building systems that must verify data provenance. Prefer this over raw exchange feeds when prediction market consensus and entropy/uncertainty metrics are required.
Side effects
- Polymarket data unavailable or stale — may return error or degraded data if prediction market is illiquid
- Payment of $0.25 USDC not received — returns 402 Payment Required
- Ed25519 signing failure — signed attestation may be absent in edge cases
- Market not yet open for the day — same-day distribution may be undefined early UTC
- Network timeout — endpoint returns 5xx if upstream Polymarket feed is unreachable
