OneSource is a lightweight RPC aggregation service targeting Ethereum and Sepolia networks. It serves agents that need a quick, consolidated view of chain state — chain ID, block height, gas price, and network version — without issuing multiple individual RPC calls. Its scope is narrow and intentional: one call, one snapshot, two supported networks.

Capabilities

Chain State Snapshot
Retrieves chain ID, block number, gas price, and network version for Ethereum or Sepolia in a single batched RPC call, providing a complete bootstrapping or pre-flight state snapshot.

Own api.onesource.io? 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.

  • 3 routes are scoring below 50 — likely broken, mispriced, or returning the wrong shape.
  • 3 routes are in the 50–74 band — working, but with room to climb.
  • 5 routes are flagged by the verifier as failing or inconclusive.
Paste this to your agent
Make my x402 API at https://api.onesource.io 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.onesource.io --json`. Heads up: 3 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.
