The price layer for autonomous agents.
The price check an agent runs before it spends. One call returns a current price and a live link to act on — so an agent can act on a price it can verify.
Price anything. Right now.
Type a product, a coin, or a generic drug. We route it to the right oracle and show the genuine best price — the same call your agent makes. A few free looks per visitor; grab a key for unlimited.
Connect your agent in one line.
Drop AgentsPrice into your agent to fetch the best available price across major sellers — one MCP line, or one API call. Free to start.
Stores we compare.
Top retailers we track and compare across. Live, ranked prices are in the comparison below.
Best price across major sellers.
Genuine prices pulled live, ranked cheapest-first, with the spread you save versus the worst venue. Every row links to a real place to buy.
| Item | Best price | Best seller | Sellers | You save |
|---|
An example transaction, run live.
Exactly what your agent would do: compare every seller, verify the match, act on the genuine best price. Driven by a real deal on steep discount right now — never a staged number.
Built for automated buyers.
An agent acts directly on the field you return, with no person to catch an error. Every response is structured to be verified and acted on without review.
Real and sourced
Every price comes from a named source. If an upstream fails you get clearly flagged stale data or an error — not an estimate.
Actionable
Each result carries a live buy link, the winning venue, and how many sellers were compared — so the price can be acted on directly.
Decision-ready
We return the ranked answer — cheapest verified price, who has it, the savings — not a raw dump your agent has to clean and sort.
Predictable contract
Stable JSON schema, typed fields, explicit units, deterministic 401 / 429 / 404 errors, and your remaining quota in every single response.
Standing queries soon
Subscribe an agent to a condition — "anything over 75% off near 06010" — and get matches pushed the moment they appear, instead of polling.
Discoverable
An OpenAPI spec, an MCP server, and llms.txt so an agent — or the dev wiring one — can find and call you correctly on the first try.
The Colosseum — list free, ranked by real savings.
An open listings marketplace where a deal has to earn its place. Anyone lists for free; every listing carries a live-market verdict — beats, at, or above the current market — checked against the same price engine. Agents query the arena with a plan key; ranking is by measured savings, and placement isn't for sale.
GET /api/colosseum · post a want: /api/wants/submit
Categories and live status.
Source-agnostic adapters under one schema. Live where a source is wired, clearly badged where it isn't — same rule for every category.
One endpoint. One header. An answer you can act on.
Authenticate with a bearer key, name a category, read the ranked deals. Metering and quota come back in the response — no second call.
Metered access. Transparent pricing.
Keys are hashed, never stored raw. Every plan is rate-limited per minute and capped per month, enforced on the billable endpoint.
