The problem
Your API can be perfect and still make $0 from agents — not because the product is bad, because agents don’t read marketing pages.
- They don’t fall in love with README prose.
- They don’t “discover” you via a blog tour.
- They query capability indexes, match intent, then pay.
If you’re not in a ranked, priced, discoverable index, you are invisible.
What teams ship vs what agents need
| What teams ship | What agents need |
|---|---|
| README + docs | Machine-readable capability |
| OpenAPI | Ranked match against intent |
| MCP tools | Discovery + price + reputation |
| “Just call us” | Pay rail (x402 / subscription) |
MCP alone is not discovery. It’s a private toolbox until something ranks and routes intent to you.
What we built
- IMP (Intention Market Protocol) — open ranking rules so capabilities can be compared fairly.
github.com/Timwal78/intention-market-protocol - AMB (Agent Manifest Beacons) — each API broadcasts what it does, price, rails, and quality.
- Premium Index (hosted) — live Match API so you don’t babysit infra: keys, metering, ranking, AMB distribution, multi-rail x402.

Pricing (live)
| Plan | Price | You get |
|---|---|---|
| Open source | $0 | Self-host a correct index |
| Starter | $49/mo | 100k matches · hosted API · <80ms target · 99.5% uptime target |
| Pro | $199/mo | 1M matches · priority ranking · <50ms · 99.9% |
| Enterprise / Federal | Custom | Private index · SDVOSB path (UEI G24VZA4RLMK3 · CAGE 21U51) |
Protocol free. Premium Index paid.
Category grows; best-operated index wins — same model as every serious open protocol.
Start Starter — $49/mo API docsWhy pay if the protocol is free?
You pay for hosted performance, curation, multi-host AMB distribution, ranking, SLA, and enterprise controls — not for permission to read the spec.
Agents choose the index that is fastest, most reliable, highest quality, and best distributed. Forks are healthy. Operators still win.
The “API killer” (honest version)
We’re not killing APIs. We’re killing invisible, unranked, unpaid endpoints.
| Dies | Survives |
|---|---|
| README-only | Agent-discoverable schema |
| No price rail | x402 / clear meter |
| No rank / beacon | AMB + reputation |
| Human sales only | Match → hire → pay |
x402 pays the call. Premium Index makes the call findable.
Quick start
FAQ
Does MCP make my API discoverable?
MCP exposes tools to a client. Discovery needs ranked indexes and beacons so agents outside your session can find and hire you.
Can others run their own index?
Yes — intentional. Agents still prefer the fastest, most trusted, best-distributed operator.
Who is this for?
MCP/tool API teams who want agent hire, x402 builders with payment but zero discovery, anyone done with “agents will find us” hopium.
