api.myceliasignal.com
Mycelia Signal is a paid oracle API serving agents and smart contracts that need cryptographically verifiable market data or real-time network fee estimates. It covers a narrow but precise set of outputs: one signed price pair (ETH/EUR), one signed macro stress index, and three chain-specific gas oracles. It is not a general-purpose price feed or DEX aggregator — its value is in attestation quality and multi-source aggregation rather than breadth of coverage.
Capabilities
Signed Price Oracles
Provides cryptographically signed, verifiable price and market-condition data suitable for on-chain oracle feeds or agent risk logic. Outputs include Ed25519 signatures, public keys, and canonical payloads.

EVM Gas Oracles
Returns current gas price data (Gwei, base fee, estimated USD cost) for three EVM networks — Base, Arbitrum, and Polygon — aggregated from multiple RPC sources to support transaction cost estimation and submission decisions.

Workflows
Pre-Transaction Cost and Stress Check
Use when an agent needs to decide whether to submit a transaction on Base, Arbitrum, or Polygon under current market conditions — combining network fee data with a macro stress reading to gate execution.
- 1fetch-market-stress-indexRetrieve the signed MSSI stress score and regime classification to determine whether market conditions are within acceptable risk thresholds for execution.
- 2fetch-base-gas-oracleIf targeting Base, fetch current gas price and estimated USD transaction cost to confirm fees are within budget before submitting.
ETH/EUR Oracle Feed with Stress Context
Use when an agent needs to price ETH in EUR for a smart contract or risk model and also wants a macro stress signal to contextualize the price reading.
- 1fetch-eth-eur-oracle-priceFetch the signed ETH/EUR price attestation for use in oracle ingestion or contract feed.
- 2fetch-market-stress-indexFetch the signed MSSI to provide regime context (e.g., high volatility, stablecoin peg deviation) alongside the price data.

Own api.myceliasignal.com? List it with your agent
Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
- 21 of 76 routes have never been scored — the audition tests them for the first time.
- 4 routes are scoring below 50 — likely broken, mispriced, or returning the wrong shape.
- 5 routes are in the 50–74 band — working, but with room to climb.
- 6 routes are flagged by the verifier as failing or inconclusive.

Make my x402 API at https://api.myceliasignal.com discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://api.myceliasignal.com --json`. Heads up: 21 routes have never been scored and 4 routes are scoring below 50 — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
