Payout address changes
The address this service asks to be paid at changed. This listing switches to a new address once the live 402 response has asked for it on every check for 24 hours from the same host, or after an admin review. Volume paid to the previous address stays with this service; volume paid to the new address counts from the date of the change, and daily totals include that whole day.

How the score works
What the score read on this service: status online, 98% uptime 30d, 851ms response p95, x402 compliance 14 of 14, $0.01 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.
The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.
Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.
It is a score inside AI, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 222 listings, this one among them: the same 222 the position above is counted against. When the two differ, the field is the wider one, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.
Settled via coinbase ($90.01, 4,853 tx). Traction is a conservative undercount; first settlement seen 2026-07-27.
All measured facts
What it does
Pay-per-request LLM inference over x402. 263 models on Venice AI supply, including uncensored lines. OpenAI-compatible chat and images plus Anthropic messages. Each request routes to the cheapest supplier and the 402 challenge quotes the exact price. Overpayment banks as reusable credit for the paying wallet.
Gondola is a listed x402 AI API. Captured payment terms name Base. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.
Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Concentrated volume is one rule applied to every listed service: the 3 largest paying addresses hold at least 90% of 30d volume, with at least $10 of volume and 50 settlements in the same 30 days. While it applies, this service's volume counts as 0 in the Recommended and Highest volume sorts of the services list. The label says where the payments came from, not why.
Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.
