Output
Returns a JSON object with: (1) embedding object containing the model name and input cost in micros per million tokens (e.g. a typical 75-token fact costs ~10 micros); (2) dreaming object keyed by model name, each with input and output micros per million tokens for server-managed memory consolidation; (3) free_operations array listing which operations cost nothing (e.g. recall, expand); (4) pricing_notes string explaining the prepaid refundable escrow model where write margins fund free reads and permanent encrypted storage.
Example use cases
Check memory costs before depositing
“Before I deposit any USDC into my memory balance, can you pull the current pricing rates for memory.withzero.xyz so I know exactly what embedding and dreaming operations will cost me?”
Audit agent memory spend
“I want to audit how much my agent has been spending on memory operations — can you fetch the latest rates for embedding and dreaming from memory.withzero.xyz, including which operations are free, so I can estimate the total cost?”
Compare dreaming model prices
“What dreaming models are currently available on memory.withzero.xyz and how do their input and output costs compare, so I can pick the most cost-effective one for large-scale memory consolidation?”
Technical details
Endpoint
GEThttps://memory.withzero.xyz/api/v1/ratesWhen to prefer
Use this endpoint before depositing USDC or calling remember() to understand current costs and avoid unexpected charges. Prefer this over hardcoded assumptions about pricing, especially before large-scale memory write operations or when auditing agent spend. This is the canonical source of truth for all memory.withzero.xyz operation costs.
Side effects
- Service unavailable (5xx) if the memory backend is down
- Unexpected response structure if the pricing schema changes without notice
- Rate structure may be empty or partial if new models are being onboarded
