The Graph
Where the record is kept. Spend history you can verify, and pricing that refuses to guess.
The Graph does two things here. It records settled payments so your spend history can be checked against the chain rather than trusted from our database, and it prices purchases in dollars when you set a dollar limit.
Two price sources, deliberately
A single price source is a single thing to manipulate. If your agent's ceiling is set in dollars, then whoever controls the price controls the ceiling.
So Pocket asks two independent sources and requires them to agree.
Source one
price lookup
Source two
pool-derived price
Compare
agree within tolerance?
Result
a price, or nothing
Two independent sources are compared; disagreement means no price at all
It refuses rather than guesses
When the two disagree beyond tolerance, or either is unavailable, there is no price. Pocket does not fall back to one source and does not use a stale figure.
Your dollar limit then refuses the purchase.
This is deliberate. Setting a limit in dollars means dollars matter. Ignoring the limit because a price feed was down would be the wrong reading, and guessing would be worse.
Limits set in tokens keep working throughout. Only the dollar rule is affected.
Spend history you can check
Your payments screen reads from an index of settled transfers, so the totals can be verified against what actually happened on the chain rather than only against our own records. If the two ever diverge, that is a fact worth surfacing rather than papering over.
The spend summary tells you which source answered:
{ "periodSpend": "15.27", "currency": "USDC", "source": "the-graph" }When the index is unreachable it falls back to reading our database directly and
reports source: "ledger". Same numbers, weaker guarantee, and it says which
you got.
