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 last block at or before the requested timestamp on the specified chain (block number, hash, and timestamp), plus the immediately following block — giving a two-block window bracketing the requested moment.
Example use cases
Anchor historical DeFi event to block
“I need to know which Ethereum block was active at the moment of the USDC depeg on March 11 2023 at 17:00 UTC — give me the last block at or before that time and the next one.”
Sync off-chain timestamp to Base block
“We recorded a trade at Unix timestamp 1700000000 on Base — what block does that correspond to? I need the block at or before that time and the following block.”
Set snapshot block for governance vote
“We're taking a governance snapshot for our DAO on Ethereum at 2024-06-15T12:00:00Z noon UTC — what block should we use as the cutoff? Give me the block at or before that time and the next block.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/chain/block-at?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to map a wall-clock time (Unix seconds or ISO 8601 datetime) to a specific on-chain block number on Ethereum or Base. It is the right choice for anchoring historical events, setting snapshot blocks for governance, or correlating off-chain timestamps to on-chain state. Prefer it over general blockchain RPC calls when you need a simple, pay-per-call REST API without setting up a full node or SDK.
Side effects
- Invalid chain value (not 'ethereum' or 'base') returns a validation error
- Timestamp out of supported range (future or before genesis) returns an error
- Malformed ISO 8601 or non-numeric string timestamp causes a parse error
- Network or RPC unavailability may cause a 5xx response
- Payment not provided or insufficient causes an HTTP 402 response
