Pricing

SingIt vs BlockRun: per-request prices.

One reference question, priced live on both sides: SingIt's own 402 ceilings against BlockRun's published per-token price plus their flat fee. No invented numbers — every figure below is read straight from each side's own pricing at page load.

The reference question.

USDC on Base, for the reference request above. **SingIt upto** is the pay-as-you-go (upto) price: the ceiling the reference request would be asked to authorize; a real answer normally settles for less once it comes back. **SingIt exact** is the flat exact-scheme ceiling, charged in full with no metering; for Claude Opus it carries room for the model's thinking tokens, so sign upto there. **BlockRun** is their published per-token price for the same request, plus their flat per-request fee, from the snapshot dated … (source: blockrun.ai/api/v1/models).

"Difference" is BlockRun's price for the reference request minus SingIt's upto price for the same request; a positive amount is what SingIt would save. Matched by BlockRun's model id (after the provider prefix) against SingIt's own model id. SingIt's side: ask.singitai.app/pricing.json, free, no payment, computed from the same code the 402 challenge uses. BlockRun's side: a committed snapshot of blockrun.ai/api/v1/models (scripts/blockrun-prices-snapshot.mjs), since the page cannot call blockrun.ai directly from the browser.
