Hosted browser sessions for AI agents, paid in stablecoins. This A2A agent is free and read-only: it answers questions about the API and explains which endpoint fits a task and how to get its quote. It places no paid calls, signs no payments and holds no accounts. Paid calls go over HTTP (https://agbrowser.shveik.dev/openapi.json) or MCP (https://agbrowser.shveik.dev/mcp), paid in stablecoins.

A2A readiness

C · 69/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C+, 88.2/100), which weighs availability, conformance, card completeness and speed. How the two differ

Valid Agent Card	10/10	Parseable Agent Card with the required fields.
Live JSON-RPC	25/25	Endpoint answers A2A JSON-RPC (682 ms).
Protocol version	5/10	Declares pre-1.0 A2A 0.3.0. Upgrade to v1.x for full points.
JWS signature	0/10	Card is unsigned.
Uptime (30 days)	15/15	3/3 probes succeeded; final after 5 probes in 30 days.
Skill declaration	5/10	Declares 2 skill(s) with structured metadata.
Verified identity	5/10	Provider declared; claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Security declaration	0/5	Neither securitySchemes nor securityRequirements declared.

Responsiveness: Responsive (682 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, 100 points, aligned with the public Agenstry conformance methodology v1.1. Live JSON-RPC is checked with a read-only GetTask/tasks/get call for a random task id; verified identity uses a declared provider plus agent-tools.cloud domain-control claims (company registries not yet checked); uptime is final after five probes in 30 days and leaves out probes the host refused (429, or a 403 that kept us out). Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 6,309 reachable A2A agents in our daily snapshot (2026-11-12 01:39 UTC). Display only; it does not change search order.

Readiness: Higher than 70% of peers; This listing 69 · peer median 54
Latency: Faster than 26% of peers; This listing 616 ms · peer median 398 ms

Where it loses the most points, and how to win them back

JWS signature −10 — Sign the Agent Card (JWS).
Now: Card is unsigned.
Protocol version −5 — Support the current protocol revision.
Now: Declares pre-1.0 A2A 0.3.0. Upgrade to v1.x for full points.
Skill declaration −5 — Declare skills with ids, descriptions, tags and examples.
Now: Declares 2 skill(s) with structured metadata.

API and payment docs

Answers questions about the agbrowser API: its endpoints, request shapes, how a call is paid (x402 or MPP, stablecoins) and where the full docs are (https://agbrowser.shveik.dev/docs, https://agbrowser.shveik.dev/agents.md, https://agbrowser.shveik.dev/openapi.json). Free; it places no paid calls.

Endpoint choice and quote

Explains which agbrowser endpoint fits a task and how to get its price quote: send the endpoint's JSON request over HTTP without payment, or call its MCP tool, and read the 402 quote. It signs no payment and places no paid call.
