How this service works
Pay once for a cited answer synthesized from independent publishers on Tenjin. POST a question; a question the catalog cannot answer returns a free MISS and is never charged.
Output
A synthesized prose answer to the submitted question, accompanied by citations identifying the independent publishers whose content was used. If the catalog cannot answer the question, the API returns a free MISS response with no charge and no answer content.
Example use cases
DeFi market event research
“What did BitMEX announce about its exchange closure, and which tokenized fund launches happened around the same time? I need cited sources from independent publishers.”
x402 payment protocol guidance
“Ask Tenjin for a cited explanation of how x402 sellers on CDP Bazaar should handle settlement correctly — I want sourced publisher answers, not just guesses.”
Stablecoin market snapshot
“What's the latest on stablecoin float and BTC price movement near $64,000? Get me a cited synthesis from Tenjin with publisher references.”
Technical details
Endpoint
POSThttps://tenjin.blog/api/answerWhen to prefer
Choose this endpoint when you need a cited, synthesized answer drawn from curated independent publishers rather than a raw web search or LLM hallucination. It is especially well-suited for questions about crypto markets, DeFi events, and emerging web3 topics covered by Tenjin's publisher catalog. The pay-on-hit model makes it cost-efficient: unanswerable questions cost nothing, so it can be used speculatively. Prefer it over general search when source provenance and citation quality matter.
Side effects
- MISS response when the question falls outside the catalog — returned free with no charge
- Ambiguous or overly broad questions may yield partial answers or a MISS
- Payment failure via x402 protocol if wallet has insufficient USDC
- Network or service errors returning non-200 HTTP status
- Question phrasing too vague to match catalog entries
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| maxPrice | string | Optional ceiling on the flat answer price, in atomic USDC units as a digit string ("10000" = $0.01). Below the quoted price the request is refused with `max_price_below_quote` rather than degraded; it never narrows which pieces the answer draws on. |
| question | string | The question to answer, 1 to 512 characters. Leading and trailing whitespace is trimmed before the length check, so an all-whitespace value is rejected. |
| freshWithin | string | Optional recency window as an ISO 8601 duration, P<n> followed by D, W, M or Y (for example "P30D"). n must be nonzero. |
