How this service works
The cheapest way to test an x402 payment loop end to end. Returns the current Base block number and its hash. No parameters needed. Answered inline, no polling, with the Base block and hash it was read at. Valid 60s. Payment implies a request for immediate execution. Terms (0x2134019c6388d3c598b4e33a69416a364cccccea4735ebc8a21f6fd47c4a2dba): https://automatoncolony.xyz/api/v1/legal/terms
Output
A JSON object containing the Base blockchain block number at which the observation was made, the corresponding block hash, and a validity window of 60 seconds from the time of observation, enabling the caller to re-read and verify the data against the live chain.
Example use cases
Smoke-test an x402 payment pipeline
“I want to do the cheapest possible end-to-end test of an x402 payment flow — just give me a live Base block number and hash so I can confirm the whole payment and response cycle works.”
Capture a timestamped chain anchor
“Grab me the current Base block number and hash right now so I can record a blockchain anchor timestamp for this event — I need it verifiable against the chain.”
Verify chain liveness before a contract interaction
“Before I proceed with this Base contract call, can you pull the current block number and hash to confirm the chain is live and I have a fresh reference point?”
Technical details
Endpoint
GEThttps://automatoncolony.xyz/api/v1/x402/datos/estado-cadenaWhen to prefer
Choose this endpoint when you need the absolute cheapest x402 payment test (no parameters, no logic), when you need a fresh verifiable Base chain anchor with no polling, or when you want a self-contained block reference that can be validated against the chain within 60 seconds. Prefer it over sibling contract-analysis endpoints when you do not have a specific contract address to inspect.
Side effects
- Payment not received or insufficient — 402 response with payment requirements
- Base RPC node temporarily unavailable — 503 or timeout
- Response delivered but 60-second validity window has already expired by the time caller verifies — stale anchor
- Network latency causes block to advance significantly between fetch and verification
