How this service works
Payment-gated AI and browser automation API using the x402 protocol. All /v1/* endpoints require USDC payment on Base (eip155:8453) via x402 v2 exact scheme.
Output
A confirmation response indicating whether the key-value pair was successfully written to the store. May include the key name, a success status, and metadata about the write operation. Payment of $0.003 USDC on Base (eip155:8453) via x402 v2 is required before the write is processed.
Example use cases
Agent state checkpoint storage
“Save the current agent state by storing the value 'step3_complete' under the key 'workflow_checkpoint' in Tanship's KV store using my USDC wallet on Base.”
Feature flag persistence
“Set the key 'feature_dark_mode' to 'enabled' in the Tanship KV store so my app can retrieve it later.”
Session token caching
“Write the token 'tok_abc123' under the key 'user_session_42' to Tanship's remote key-value store — I need it persisted for a few hours.”
Technical details
Endpoint
POSThttps://x402.tanship.dev/v1/kv/set?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use remote key-value write operation and are already operating within the x402 micropayment ecosystem on Base. Ideal for AI agents that need to persist small state values, flags, or tokens without managing a full database, especially when cost-per-write accountability via USDC is desired. Not suited for bulk storage, large payloads, or use cases requiring free or subscription-based storage.
Side effects
- Payment not provided or insufficient USDC — returns HTTP 402 with x402 payment requirements

- Key or value exceeds allowed size limits — returns HTTP 413 or 400
- Authentication or wallet verification failure — returns HTTP 401
