How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
Returns the latest answer from the specified Chainlink price feed, including the price value, round ID, on-chain update timestamp, and a boolean staleness flag indicating whether the feed has exceeded its expected heartbeat interval.
Example use cases
DeFi liquidation staleness check
“Check the Chainlink BTC/USD price feed on Ethereum and tell me if it's gone stale — I need the round ID and last update time too.”
Cross-chain price comparison
“Fetch the Chainlink cbETH/ETH price on Base and the stETH/USD price on Ethereum so I can compare the two liquid staking token valuations right now.”
Portfolio valuation snapshot
“Give me the latest Chainlink oracle prices for ETH/USD and LINK/USD on Base, including when each feed was last updated.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/chain/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a verifiable, manipulation-resistant Chainlink oracle price rather than a DEX spot price. It is ideal for DeFi applications requiring on-chain price provenance, staleness detection, and round-level auditability. Prefer it over DEX-derived prices when you need to match the exact price source used by Chainlink-integrated smart contracts on Ethereum or Base.
Side effects
- Unsupported pair/chain combination (e.g. stETH/USD on Base) returns an error
- Feed temporarily unavailable or RPC node unreachable
- Staleness flag is true if the feed hasn't updated within its heartbeat window
- Invalid enum value for pair or chain returns a validation error
- Payment failure via x402 protocol results in 402 response
