How this service works
$0.01 USDC required (x402 / Base) Paid 0.01 USDC. Detected plan, price, and billing-period changes for one catalog slug, newest first, with a paging cursor. Empty array means nothing has been recorded yet, not that the vendor’s price has been stable forever. Check free lastChangeAt first. No API key needed. Pay with any x402-compatible wallet that holds USDC on Base. If your agent does not yet have a funded wallet, set one up via Coinbase Agentic Wallet or Base MCP — then standard x402 clients will pay and retry automatically.
Output
A JSON array of change records for the DeepSeek catalog slug, ordered newest first. Each record describes a detected change in plan name, price, or billing period. The response also includes a nextBefore opaque cursor for fetching the next (older) page, and a lastChangeAt field indicating when the most recent change was recorded. An empty array means no changes have been recorded yet, not that pricing has been stable forever.
Example use cases
Audit DeepSeek price history
“Have there been any recorded changes to DeepSeek's pricing plans or billing periods? Show me the 20 most recent ones, newest first.”
Paginate older DeepSeek price changes
“I already pulled the first page of DeepSeek price changes — now get me the next page of older records using the cursor from that last response.”
Detect recent DeepSeek price hikes
“Check if DeepSeek has changed any of its API pricing or billing tiers in the Pricing State API and let me know what changed most recently.”
Technical details
Endpoint
GEThttps://pricing-state-api.replit.app/api/monitors/deepseek/changes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the historical change log for DeepSeek pricing — not just the current snapshot. Prefer it over the snapshot endpoint when you need to audit when prices changed, detect recent price hikes or cuts, or page through a timeline of plan/billing-period changes. It is the right choice if your agent needs to answer 'what changed and when' rather than 'what is the price right now'.
Side effects
- Empty array returned — no changes have been recorded yet for DeepSeek (not necessarily stable pricing)
- Invalid or expired cursor passed in 'before' parameter — API may return an error or unexpected page
- Payment failure — x402 wallet not funded with USDC on Base, blocking access
- Rate limiting or quota errors if the endpoint is called too frequently
- Stale data — the service may not have crawled DeepSeek's pricing page recently
